Commit history, logo license, full-arc fix.

- Commit history added to repo, as an easier way for people to see view
the changes over time.

- Grbl logo copyright license added. All rights reserved with regards
to the Grbl logo.

- G2/3 full circles would sometime not execute. The problem was due to
numerical round-off of a trig calculation. Added a machine epsilon
define to help detect and correct for this problem. Tested and should
not effect general operation of arcs.

Author: Sonny Jeon
Subject: Fix bug with premature step end. Refactored _delay_ms() and square() for better portability.
- Fixed a premature step end bug dating back to Simen's 0.7b edge
version is fixed, from which this code is forked from. Caused by Timer2
constantly overflowing calling the Step Reset Interrupt every 128usec.
Now Timer2 is always disabled after a step end and should free up some
cycles for the main program. Could be more than one way to fix this
problem. I'm open to suggestions.
- _delay_ms() refactored to accept only constants to comply with
current compilers. square() removed since not available with some
compilers.

Subject: Extended position reporting with both home and work coordinates. Home position now retained after reset. Other minor changes/fixes.
- Grbl now tracks both home and work (G92) coordinate systems and does
live updates when G92 is called.
- Rudimentary home and work position status reporting. Works but still
under major construction.
- Updated the main streaming script. Has a disabled periodic timer for
querying status reports, disabled only because the Python timer doesn't
consistently restart after the script exits. Add here only for user
testing.
- Fixed a bug to prevent an endless serial_write loop during status
reports.
- Refactored the planner variables to make it more clear what they are
and make it easier for clear them.

Subject: Position reporting, refactored system variables, serial print fixes, updated streaming scripts.
- Added machine position reporting to status queries. This will be
further developed with part positioning/offsets and maintaining
location upon reset.
- System variables refactored into a global struct for better
readability.
- Removed old obsolete Ruby streaming scripts. These were no longer
compatible. Updated Python streaming scripts.
- Fixed printFloat() and other printing functions.
- Decreased planner buffer back to 18 blocks and increased TX serial
buffer to 64 bytes. Need the memory space for future developments.
- Begun adding run-time modes to grbl, where block delete toggle, mm/in
reporting modes, jog modes, etc can be set during runtime. Will be
fleshed out and placed into EEPROM when everything is added.

Subject: Initial v0.8 ALPHA commit. Features multi-tasking run-time command execution (feed hold, cycle start, reset, status query). Extensive re-structuring of code for future features.
- ALPHA status. - Multitasking ability with run-time command executions
for real-time control and feedback. - Decelerating feed hold and resume
during operation. - System abort/reset, which immediately kills all
movement and re-initializes grbl. - Re-structured grbl to easily allow
for new features: Status reporting, jogging, backlash compensation. (To
be completed in the following releases.) - Resized TX/RX serial buffers
(32/128 bytes) - Increased planner buffer size to 20 blocks. - Updated
documentation.

Author: Sonny Jeon
Subject: Third time's a charm! No more deceleration issues! Updated grbl version and settings. General cleanup.
- Fleshed out the original idea to completely remove the long slope at
the end of deceleration issue. This third time should absolutely
eliminate it.
- Changed the acceleration setting to kept as mm/min^2 internally,
since this was creating unneccessary additional computation in the
planner. Human readable value kept at mm/sec^2.
- Updated grbl version 0.7d and settings version to 4. NOTE: Please
check settings after update. These may have changed, but shouldn't.
- Before updating the new features (pause, e-stop, federate override,
etc), the edge branch will soon be merged with the master, barring any
immediate issues that people may have, and the edge branch will be the
testing ground for the new grbl version 0.8.

Subject: Forgot something! Comments on what the last change does.
----------------
Date: 2011-10-06
Author: Sonny Jeon
Subject: Minor update to further eliminate the ole long slope deceleration issue. New update note!
- Added another way to further ensure the long slope deceleration issue
is eliminated. If the stepper rate change is too great near zero, the
stepper rate is adjusted at half increments to the end of travel,
creating a smooth transition. - If the new STEPPER_IDLE_LOCK_TIME is
set as zero, this delay is not compiled at compile-time. - NOTE: The
next update is likely going to be major, involving a full re-write of
the stepper.c program to integrate a simple way to apply pauses,
jogging, e-stop, and feedrate overrides. The interface should be
flexible enough to be easily modified for use with either hardware
switches or software commands. Coming soon.
----------------
Date: 2011-09-29
Author: Sonny Jeon
Subject: Added complete stop delay at the end of all motion. Moved grbl preprocessor script into a new repository.
Added a very short (25 ms) user-definable delay before the steppers are
disabled at the motors are disabled and grbl goes idle. This ensures
any residual inertia at the end of the last motion does not cause the
axes to drift and grbl to lose its position when manually entering
g-code or when performing a tool change and starting the next
operation.

Subject: Updated some comments and fixed a bug in the new stepper logic.
- The stepper logic was not initiating the decelerations for certain
cases. Just re-arranged the logic to fix it.
----------------
Date: 2011-09-24
Author: Sonny Jeon
Subject: Fixed long slope at deceleration issue. Moved things into config.h. New MINIMUM_PLANNER_SPEED parameter.
- The long standing issue of a long slope at deceleration is likely
fixed. The stepper program was not tracking and timing the end of
acceleration and start of deceleration exactly and now is fixed to
start and stop on time. Also, to ensure a better acceleration curve fit
used by the planner, the stepper program delays the start of the
accelerations by a half trapezoid tick to employ the midpoint rule. -
Settings version 3 migration (not fully tested, but should work) -
Added a MINIMUM_PLANNER_SPEED user-defined parameter to planner to let
a user change this if problems arise for some reason. - Moved all
user-definable #define parameters into config.h with clear comments on
what they do and recommendations of how to change them. - Minor
housekeeping.
----------------

Author: Sonny J
Subject: Fixed minor bugs in planner. Increased max dwell time. Long slope bug stop-gap solution note.
- Fixed the planner TODO regarding minimum nominal speeds. Re-arranged
calculations to be both more efficient and guaranteed to be greater
than zero. - Missed a parenthesis location on the rate_delta
calculation. Should fix a nearly in-perceptible issue with incorrect
acceleration ramping in diagonal directions. - Increased maximum dwell
time from 6.5sec to an 18hour max. A crazy amount more, but that's how
the math works out. - Converted the internal feedrate values to mm/min
only, as it was switching between mm/min to mm/sec and back to mm/min.
Also added a feedrate > 0 check in gcode.c. - Identified the long slope
at the end of rapid de/ac-celerations noted by stephanix. Problem with
the numerical integration truncation error between the exact solution
of estimate_acceleration_distance and how grbl actually performs the
acceleration ramps discretely. Increasing the
ACCELERATION_TICKS_PER_SECOND in config.h helps fix this problem.
Investigating further.

Subject: More '%' modulo opertor removals and some housecleaning.
- Serial functions contained quite a few modulo operations that would
be executed with high frequency when streaming. AVR processors are very
slow when operating these. In one test on the Arduino forums, it showed
about a 15x slow down compared to a simple if-then statement. -
Clarified some variable names and types and comments.

Subject: Further planner improvements and misc minor bug fixes. Memory savings and increased buffer size.
- Update grbl version and settings version to automatically reset
eeprom. FYI, this will reset your grbl settings. - Saved
3*BLOCK_BUFFER_SIZE doubles in static memory by removing obsolete
variables: speed_x, speed_y, and speed_z. - Increased buffer size
conservatively to 18 from 16. (Probably can do 20). - Removed expensive!
modulo operator from block indexing function. Reduces significant
computational overhead. - Re-organized some sqrt() calls to be more
efficient during time critical planning cases, rather than non-time
critical. - Minor bug fix in planner max junction velocity logic. -
Simplified arc logic and removed need to multiply for CW or CCW
direction.
----------------
Date: 2011-09-06
Author: Sonny J
Subject: Optimized planner re-write. Significantly faster. Full arc support enabled by rotation matrix approach.
- Significant improvements in the planner. Removed or reordered
repetitive and expensive calculations by order of importance:
recalculating unchanged blocks, trig functions [sin(), cos(), tan()],
sqrt(), divides, and multiplications. Blocks long enough for nominal
speed to be guaranteed to be reached ignored by planner. Done by
introducing two uint8_t flags per block. Reduced computational overhead
by an order of magnitude. - Arc motion generation completely
re-written and optimized. Now runs with acceleration planner. Removed
all but one trig function (atan2) from initialization. Streamlined
computations. Segment target locations generated by vector
transformation and small angle approximation. Arc path correction
implemented for accumulated error of approximation and single precision
calculation of Arduino. Bug fix in message passing.
----------------

Author: Sonny J
Subject: Minor update for memory savings in ring buffer and fleshed out commenting.
No changes in functionality. Path vectors moved from ring buffer to
local planner static variables to save 3*(BUFFER_SIZE - 1) doubles in
memory. Detailed comments. Really need to stop micro-updating. Should be
the last until a planner optimization (ala Jens Geisler) has been
completed.

Author: Sonny J
Subject: More minor bug fixes in planner.
Reverse planner was over-writing the initial/buffer tail entry speed,
which reset the forward planner and caused it to lose track of its
speed. Should now accelerate into short linear segments much nicer now.

Subject: Add G02/03 arc conversion/pre-processor script and example streaming script
Beta pre-processor script used to clean and streamline g-code for
streaming and converts G02/03 arcs into linear segments. Allows for full
acceleration support if the pre-processed g-code is then streamed to
grill, sans G02/03 arcs. Added a simple example streaming script for
Python users.
----------------

Author: Sonny J
Subject: Significantly improved junction control and fixed computation bugs in planner
- Junction jerk now re-defined as junction_deviation. The distance from
the junction to the edge of a circle tangent to both previous and
current path lines. The circle radii is used to compute the maximum
junction velocity by centripetal acceleration. More robust and
simplified way to compute jerk. - Fixed bugs related to entry and exit
factors. They were computed based on the current nominal speeds but not
when computing exit factors for neighboring blocks. Removed factors and
replaced with entry speeds only. Factors now only computed for stepper
trapezoid rate conversions. - Misc: Added min(), next_block_index,
prev_block_index functions for clarity.

Subject: Moved comment and block delete handling into protocol.c from gcode.c. Fixes bug when comment and block delete are not isolated. Blank lines ignored.
Comments, block delete characters, and blank lines are no longer passed
to the gcode parser and should free up some memory by ignoring these
characters. Gcode parser now expects clean gcode only. There was a bug
if there were block deletes or comments not in the first character (i.e.
spindle on/off for proofing geode without turning it on, or a NXX
followed by a comment). This should fix it by bypassing the problem.
Left a commented line for easily turning on and off block deletes for a
later feature, if desired.

Subject: Homing search sequence now compile-time option. New defaults.h file. Tidying up.
- The homing sequence is now a compile-time option, where a user can
choose which axes(s) move in sequence during the search phase. Up to 3
sequences. Works with the locating phase and the pull-off maneuver.
- New defaults.h file to store user generated default settings for
different machines. Mainly to be used as a central repo, but each set
may be select to be compiled in as a config.h define.

Subject: Added Grbl state in status report. Removed switch support.
- Added Grbl state (Idle, Running, Queued, Hold, etc) to the real-time
status reporting feature as feedback to the user of what Grbl is doing.
Updated the help message to reflect this change.
- Removed switches (dry run, block delete, single block mode). To keep
Grbl simple and not muddled up from things that can easily be taken
care of by an external interface, these were removed.
- Check g-code mode was retained, but the command was moved to '$C'
from '$S0'.

Subject: Re-factored system states and alarm management. Serial baud support greater than 57600.
- Refactored system states to be more clear and concise. Alarm locks
processes when position is unknown to indicate to user something has
gone wrong.
- Changed mc_alarm to mc_reset, which now manages the system reset
function. Centralizes it.
- Renamed '$X' kill homing lock to kill alarm lock.
- Created an alarm error reporting method to clear up what is an alarm:
message vs a status error: message. For GUIs mainly. Alarm codes are
negative. Status codes are positive.
- Serial baud support upto 115200. Previous baudrate calc was unstable
for 57600 and above.
- Alarm state locks out all g-code blocks, including startup scripts,
but allows user to access settings and internal commands. For example,
to disable hard limits, if they are problematic.
- Hard limits do not respond in an alarm state.
- Fixed a problem with the hard limit interrupt during the homing
cycle. The interrupt register is still active during the homing cycle
and still signal the interrupt to trigger when re-enabled. Instead,
just disabled the register.
- Homing rate adjusted. All axes move at homing seek rate, regardless
of how many axes move at the same time. This is unlike how the stepper
module does it as a point to point rate.
- New config.h settings to disable the homing rate adjustment and the
force homing upon powerup.
- Reduced the number of startup lines back down to 2 from 3. This
discourages users from placing motion block in there, which can be very
dangerous.
- Startup blocks now run only after an alarm-free reset or after a
homing cycle. Does not run when $X kill is called. For satefy reasons

than 'dry run'.
- Trimmed all of Grbl's messages from help, status, feedback to
settings. Saved 0.6KB+ of flash space that could be used for v0.9
features.

Subject: Tweaks and bug fixes. Increase to 3 startup blocks. Remove purge/added unlock command
- Increased the number of startup blocks to 3 for no good reason other
than it doesn't increase the flash size.
- Removed the purge buffer command and replaced with an disable homing
lock command.
- Homing now blocks all g-code commands (not system commands) until the
homing cycle has been performed or the disable homing lock is sent.
Homing is required upon startup or if Grbl loses it position. This is
for safety reasons.
- Cleaned up some of the Grbl states and re-organized it to be little
more cohesive.
- Cleaned up the feedback and status messages to not use so much flash
space, as it's a premium now.
- Check g-code and dry run switches how are mutually exclusive and
can't be enabled when the other is. And automatically resets Grbl when
disabled.
- Some bug fixes and other minor tweaks.

Subject: Tweaked dry run and check g-code switches. Now resets when toggled off.
- To make managing the code easier and to help ensure a user starts
with a fresh reset, the functionality of check g-code and dry run has
been changed to automatically perform a soft reset when toggled off.
Position will not be lost, unless there is a cycle active. Feed hold
before toggling off it needed.
This is mainly a safety issue. If a user dry runs a program and kills
it mid-program, and then restarts it thinking to run it as normal, the
g-code modes that we're set may not be what they expect, and very bad
things can happen.
- NOTE: Grbl is at 83.5% of flash capacity. Not a lot of room left, but
I think we can squeeze in some more!

Subject: Runtime command pinned out! Re-organized coolant pins.
- Pinned out cycle start(A2), feed hold(A1), and reset(A0) runtime
commands. These pins are held high with the internal pull-up resistor
enabled. All you have to do is connect a normally-open switch to the
pin and ground. That's it.
- Moved the coolant control pins to A3 (and the optional mist control
to A4).
- Moved all of the MASK defines into the config.h file to centralize
them.

Subject: Tweaks and minor bug fixes. Added purge buffer command.
- Added a purge buffer (and lock) command. This is an advanced option
to clear any queued blocks in the buffer in the event of system
position being lost or homed. These queued blocks will likely not move
correctly if not purged. In typical use, the purging command releases
the homing axes lock in case a user need to move the axes off their
hard limit switches, but position is not guaranteed. Homing is advised
immediately after.
- Created a system-wide sync current position function. Cleans up some
of the repetitive tasks in various places in the code that do the same
thing.
- Removed the clear all switches command '$S'. Not really needed and
helped clean up a sync call.
- Other minor tweaks. Readme updated slightly..

Subject: New startup script setting. New dry run, check gcode switches. New system state variable. Lots of reorganizing.
(All v0.8 features installed. Still likely buggy, but now thourough
testing will need to start to squash them all. As soon as we're done,
this will be pushed to master and v0.9 development will be started.
Please report ANY issues to us so we can get this rolled out ASAP.)
- User startup script! A user can now save one (up to 5 as compile-time
option) block of g-code in EEPROM memory. This will be run everytime
Grbl resets. Mainly to be used as a way to set your preferences, like
G21, G54, etc.
- New dry run and check g-code switches. Dry run moves ALL motions at
rapids rate ignoring spindle, coolant, and dwell commands. For rapid
physical proofing of your code. The check g-code switch ignores all
motion and provides the user a way to check if there are any errors in
their program that Grbl may not like.
- Program restart! (sort of). Program restart is typically an advanced
feature that allows users to restart a program mid-stream. The check
g-code switch can perform this feature by enabling the switch at the
start of the program, and disabling it at the desired point with some
minimal changes.
- New system state variable. This state variable tracks all of the
different state processes that Grbl performs, i.e. cycle start, feed
hold, homing, etc. This is mainly for making managing of these task
easier and more clear.
- Position lost state variable. Only when homing is enabled, Grbl will
refuse to move until homing is completed and position is known. This is
mainly for safety. Otherwise, it will let users fend for themselves.
- Moved the default settings defines into config.h. The plan is to
eventually create a set of config.h's for particular as-built machines
to help users from doing it themselves.
- Moved around misc defines into .h files. And lots of other little
things.

Subject: Added block delete, opt stop, single block mode. New parser state and parameter feedback. Overhauled '$' command.
NOTE: Another incremental update. Likely buggy, still a ways to go
before everything is installed, such as startup blocks.
- Changed the '$' command to print help. '$$' now prints Grbl settings.
The help now instructs the user of runtime commands, switch toggling,
homing, etc. Jogging will be added to these in v0.9.
- Added switches: block delete, opt stop, and single block mode.
- Now can print the g-code parser state and persistent parameters
(coord sys) to view what Grbl has internally.
- Made the gc struct in the g-code parser global to be able to print
the states. Also moved coordinate system tracking from sys to gc struct.
- Changed up the welcome flag and updated version to v0.8c.
- Removed spindle speed from gcode parser. Not used.

Subject: New report module. 6 persistent work coordinates. New G-codes and settings. README and minor bug updates
(NOTE: This push is likely buggy so proceed with caution. Just
uploading to let people know where we're going.)
- New report.c module. Moved all feedback functions into this module to
centralize these processes. Includes realtime status reports, status
messages, feedback messages.
- Official support 6 work coordinate systems (G54-G59), which are
persistently held in EEPROM memory.
- New g-code support: G28.1, G30.1 stores current machine position as a
home position into EEPROM. G10 L20 Px stores current machine position
into work coordinates without needing to explicitly send XYZ words.
- Homing performed with '$H' command. G28/G30 no longer start the
homing cycle. This is how it's supposed to be.
- New settings: Stepper enable invert and n_arc correction installed.
- Updated and changed up some limits and homing functionality. Pull-off
travel will now move after the homing cycle regardless of hard limits
enabled. Fixed direction of pull-off travel (went wrong way).
- Started on designing an internal Grbl command protocol based on the
'$' settings letter. Commands with non numeric characters after '$'
will perform switch commands, homing cycle, jogging, printing
paramters, etc. Much more to do here.
- Updated README to reflect all of the new features.

Subject: New alarm method. Re(re)organized status messages.
- Installed a new 'alarm' method to centralize motion kills across
alarm or reset events. Right now, this is controlled by system abort
and hard limits. But, in the future, a g-code parser error may call
this too as a safety feature.
- Re(re)organized status messages to just print all errors, regardless
from where it was called. This centralizes them into one place.
- Misc messages method installed for any user feedback that is not a
confirmation or error. Mainly so that there is a place to perform
warnings and such.
- New stuff installed and still made the flash size smaller by saving
flash space from clearing out repeated '\r\n' pgmstrings.
- Fixed a bug where hard limits message would print everytime a system
abort was sent.
----------------
Date: 2012-10-21
Author: Sonny Jeon
Subject: Re-organized status messages to be more coherent and centralized.
- Reorganized all of the status message feedback from both the g-code
parser and settings modules to be centralized into two message modules:
status feedback from executing a line and warnings for misc feedback.
- Pulled out the printPgmString() messages in settings.c and placed it
into the new module. (settings_dump() not moved).
- Some other minor edits. Renaming defines, comment updates, etc.

Subject: Hard limits code minor updates.
- Fixed a bug that would not disable the steppers if a user issues a
system abort during a homing cycle.
- Updated the hard limit interrupt to be more correct and to issue a
shutdown for the right situations when the switch has been triggered.
- Added a status message to indicate to the user what happened and what
to do upon a hard limit trigger.
----------------
Date: 2012-10-16
Author: Sonny Jeon
Subject: Hard limits, homing direction, pull-off limits after homing, status reports in mm or inches, system alarm, and more.
- Thank you statement added for Alden Hart of Synthetos.
- Hard limits option added, which also works with homing by pulling off
the switches to help prevent unintended triggering. Hard limits use a
interrupt to sense a falling edge pin change and immediately go into
alarm mode, which stops everything and forces the user to issue a reset
(Ctrl-x) or reboot.
- Auto cycle start now a configuration option.
- Alarm mode: A new method to kill all Grbl processes in the event of
something catastrophic or potentially catastropic. Just works with hard
limits for now, but will be expanded to include g-code errors (most
likely) and other events.
- Updated status reports to be configurable in inches or mm mode. Much
more to do here, but this is the first step.
- New settings: auto cycle start, hard limit enable, homing direction
mask (which works the same as the stepper mask), homing pulloff
distance (or distance traveled from homed machine zero to prevent
accidental limit trip).
- Minor memory liberation and calculation speed ups.
----------------

Subject: Minor updates, improvements, and bug fixes.
- Allowed status_message function to be called by others. This is to
centralize all feedback into protocol.c.
- Fixed a bug where line number words 'N' were causing the parser to
error out.
- Allowed homing routine feed rates to move slower than the
MINIMUM_STEP_RATE parameter in config.h.
- Homing performs idle lock at the end of the routine.
- Stepper idle lock time will now not disable the steppers when the
value is set at 255. This is accomodate users who prefer to keep their
axes enabled at all times.
- Moved some defines around to where they need to be.

Author: Sonny Jeon
Subject: Improved homing cycle. New settings: homing enable/rates, debounce and step idle lock time.
- Homing cycle will now cycle twice (spec more/less in config) to
improve repeatability and accuracy by decreasing overshoot.
- New Grbl settings added: Enable/disable homing cycles, homing seek
and feed rates, switch debounce delay, and stepper idle lock time.
- Please note that these settings may change upon the next push, since
there will be more added soon. Grbl *should* not re-write your old
settings, just re-write the new ones. So, make sure you keep these
written down somewhere in case they get lost from a code bug.
- Refactored settings migration to be a little smaller and managable
going forward.

Subject: Limit pin internal pull-resistors enabled. Re-wrote read_double() function. Correctly changed all 'double's to 'float's.
- Limit pin internal pull-resistors now enabled. Normal high operation.
This will be the standard going forward.
- Updated all of the 'double' variable types to 'float' to reflect what
happens when compiled for the Arduino. Also done for compatibility
reasons to @jgeisler0303 's Grbl simulator code.
- G-code parser will now ignore 'E' exponent values, since they are
reserved g-code characters for some machines. Thanks @csdexter!
- The read_double() function was re-written and optimized for use in
Grbl. The strtod() avr lib was removed.

axes without exceeding acceleration limits.
- Homing now updates all internal positioning variables to machine zero
after completion.
- "Poor-man's" debounce delay added.
- Updated the delay_us() function to perform faster and more accurate
microsecond delays. Previously, the single increments would add
noticeable time drift for larger delays.

Author: Sonny Jeon
Subject: Added step pulse delay after direction set (Compile-time option only). Updated read me.
Added a compile-time only experimental feature that creates a
user-specified time delay between a step pulse and a direction pin set
(in config.h). This is for users with hardware-specific issues
(opto-couplers) that need more than a few microseconds between events,
which can lead to slowly progressing step drift after many many
direction changes. We suggest to try the hack/fix posted in the Wiki
before using this, as this experimental feature may cause Grbl to take
a performance hit at high step rates and about complex curves.

- A latency issue related to USB-to-serial converters on the Arduino
does not allow for XON/XOFF flow control to work correctly on standard
terminal programs. It seems that only specialized UI's or avoiding the
USB port all together solves this problem. However, XON/XOFF flow
control is added for advanced users only as a compile-time option. This
feature is officially *NOT* supported by grbl, but let us know of any
successes with it!

- G54 work coordinate system support. Up to 6 work coordinate systems
(G54-G59) available as a compile-time option.
- G10 command added to set work coordinate offsets from machine
position.
- G92/G92.1 position offsets and cancellation support. Properly follows
NIST standard rules with other systems.
- G53 absolute override now works correctly with new coordinate systems.
- Revamped g-code parser with robust error checking. Providing user
feedback with bad commands. Follows NIST standards.
- Planner module slightly changed to only expected position movements
in terms of machine coordinates only. This was to simplify coordinate
system handling, which is done solely by the g-code parser.
- Upon grbl system abort, machine position and work positions are
retained, while G92 offsets are reset per NIST standards.
- Compiler compatibility update for _delay_us().
- Updated README.

- Work position is set equal to machine position upon reset, as
according to NIST RS274-NGC guidelines. G92 is disabled.
- Renamed mc_set_current_position() to mc_set_coordinate_offset().

Date: 2015-03-27
Author: Sungeun Jeon
Subject: New compile options and inverse time bug fix.
- Apparently inverse time motion were not working for quite some time.
Goes to show how many people actually use it. The calculation was bad
and is now fixed in this update. It should now work correctly.
- `;` comment type is now supported. This is standard on LinuxCNC and
common on 3d printers. It was previously not supported due to not
existing in the NIST standard, which is out-dated.
- New compile-option to ECHO the line received. This should help users
experiencing very weird problems and help diagnose if there is
something amiss in the communication to Grbl.
- New compile-option to use the spindle direction pin D13 as a spindle
enable pin with PWM spindle speed on D11. This feature has been
requested often from the laser cutter community. Since spindle
direction isnt really of much use, it seemed like good good trade.
Note that M4 spindle enable counter-clock-wise support is removed for
obvious reasons, while M3 and M5 still work.

Subject: Cleaned-up limit pin reporting and comments.
- Cleaned up the limit pin state reporting option to display only the
state per axis, rather than the whole port. Its organized by an XYZ
order, 0(low)-1(high), and generally looks like `Lim:001`.
- Separated the control pin state reporting from limit state reporting
as a new compile option. This stayed the same in terms of showing the
entire port in binary, since its not anticipated that this will be
used much, if at all.
- Updated some of the gcode source comments regarding supported g-codes.

Subject: G91.1 support. Fixed a config.h option.
- G91.1 support added. This g-code sets the arc IJK distance mode to
incremental, which is the default already. This simply helps reduce
parsing errors with certain CAM programs that output this command.
- Max step rate checks werent being compiled in if the option was
enabled. Fixed now.

enabled. Due to unsigned int problem. Changed codes to positive values
since they arent shared with other codes.

Author: Sonny Jeon
Subject: New configuration options.
- New configuration option at compile-time:
- Force alarm upon power-up or hard reset. When homing is enabled,
this is already the default behavior. This simply forces this all of
the time.
- GUI reporting mode. Removes most human-readable strings that GUIs
dont need. This saves nearly 2KB in flash space that can be used for
other features.
- Hard limit force state check: In the hard limit pin change ISR, Grbl
by default sets the hard limit alarm upon any pin change to guarantee
the alarm is set. If this option is set, itll check the state within
the ISR, but cant guarantee the pin will be read correctly if the
switch is bouncing. This option makes hard limit behavior a little less
annoying if you have a good buffered switch circuit that removes
bouncing and electronic noise.
- Software debounce bug fix. It was reading the pin incorrectly for the
setting.
- Re-factored some of the $ settings code.

Subject: Improved homing limit search handling.
- Instead of a single overall max travel for a search distance for the

idle before, but now will exit with an alarm.

----------------
Date: 2015-02-11
Author: Sonny Jeon
Subject: Overhauled state machine. New safety door feature.
- Overhauled the state machine and cleaned up its overall operation.
This involved creating a new suspend state for what all external
commands, except real-time commands, are ignored. All hold type states
enter this suspend state.
- Removed auto cycle start setting from Grbl. This was not used by
users in its intended way and is somewhat redundant, as GUI manage the
cycle start by streaming. It also muddled up how Grbl should interpret
how and when to execute a g-code block. Removing it made everything
much much simpler.
- Fixed a program pause bug when used with other buffer_sync commands.
- New safety door feature for OEMs. Immediately forces a feed hold and
then de-energizes the machine. Resuming is blocked until the door is
closed. When it is, it re-energizes the system and then resumes on the
normal toolpath.
- Safety door input pin is optional and uses the feed hold pin on A1.
Enabled by config.h define.
- Spindle and coolant re-energizing upon a safety door resume has a
programmable delay time to allow for complete spin up to rpm and
turning on the coolant before resuming motion.
- Safety door-style feed holds can be used instead of regular feed hold
(doesnt de-energize the machine) with a @ character. If the safety
door input pin is not enabled, the system can be resumed at any time.

- Critical bug fix for diagonal motions that continue on the same
direction or return in the exact opposite direction. This issue could
cause Grbl to crash intermittently due to a numerical round-off error.
Grbl versions prior to v0.9g shouldnt have this issue.
- Reorganized all of the includes used by Grbl. Centralized it into a
single “grbl.h” include. This will help simplify the compiling and
uploading process through the Arduino IDE.
- Added an example .INO file for users to simply open and run when
compiling and uploading through the IDE. More to come later.

Subject: Limit/control pin state reporting option
- As a setup feature, users can compile-in input pin status reporting.
Doesnt do anything special, just prints the binary for the port. 0s
and 1s indicate low and high signals on the pins. Its a bit cryptic
right now, but its just a start.
- Added a max step rate check when writing step/mm and max rate
settings. Should help avoid people misdiagnosing problems associated
with going over the 30kHz step rate limit. Right now not enabled. Takes
up over 100k of flash. Need that room for other things right now.

- All pins, which include limits, control command, and probe pins, can
now all be configured to trigger as active-low or active-high and
whether the pin has its internal pull-up resistor enabled. This should
allow for just about all types of NO and NC switch configurations.
- The probe pin invert setting hasnt been added to the Grbl settings,
like the others, and will have to wait until v1.0. But for now, its
available as a compile-time option in config.h.

no longer issue an error when typically sent in g-code program header.
- Refactored coolant and spindle state setting into separate functions
for future features.
- Configuration option for fixing homing behavior when there are two
limit switches on the same axis sharing an input pin.
- Created a new “grbl.h” that will eventually be used as the main
include file for Grbl. Also will help simply uploading through the
Arduino IDE
- Separated out the alarms execution flags from the realtime (used be
called runtime) execution flag variable. Now reports exactly what
caused the alarm. Expandable for new alarms later on.
- Refactored the homing cycle to support CoreXY.
- Applied @EliteEng updates to Mega2560 support. Some pins were
reconfigured.
- Created a central step to position and vice versa function. Needed
for non-traditional cartesian machines. Should make it easier later.
- Removed the new CPU map for the Uno. No longer going to used. There
will be only one configuration to keep things uniform.

Subject: Updated variable spindle and new probing. Minor bug fixes.
- Minor bug fix for variable spindle PWM output. Values smaller than
the minimum RPM for the spindle would overflow the PWM value. Thanks
Rob!
- Created an optional minimum spindle PWM low-mark value as a
compile-time option. This is for special circumstances when the PWM has
to be at a certain level to be read by the spindle controller.
- Refactored the new probing commands (G38.3, G38.4, G38.5) code to
work better with the rest of Grbls systems.
- Refactored mc_probe() and mc_arc() to accept the mode of the command,
i.e. clockwise vs counter, toward vs away, etc. This is to make these
functions independent of gcode state variables.
- Removed the pull off motion in the probing cycle. This is not an
official operation and was added for user simplicity, but wrongly did
so. So bye bye.
- Created a configure probe invert mask function to handle the
different probe pin setting and probing cycle modes with a single mask.
- Minor bug fix with reporting motion modes via $G. G38.2 wasnt
showing up. It now does, along with the other new probing commands.
- Refactored some of the new pin configurations for the future of Grbl.

Subject: Minor settings number overflow bug fix.
- The `x` in `$x=val` would overflow when a value larger than 255 was
entered and passed to Grbl. This resulted with unintended parameters
being set by the overflow value. To fix, simply check for values larger
than 255 and error out.
