- 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.

Subject: Compile-option for inverting spindle enable.
|

|
||
certain electronics boards users have reported needing this.

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 isn’t 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. It’s 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 it’s not anticipated that this will be
|
||
used much, if at all.
|
||
|
||
- Updated some of the gcode source comments regarding supported g-codes.

|
||
|

|
||
|
||
- Added an include in the right spot, if a user tries to compile and
|
||
upload Grbl through the Arduino IDE with the old way.
|
||
|
||
- Fixed a minor bug with homing max travel calculations. It was causing

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 weren’t being compiled in if the option was
|
||
enabled. Fixed now.
|
||
|
||
- Alarm codes were not displaying correctly when GUI reporting mode was
|
||
enabled. Due to unsigned int problem. Changed codes to positive values
|
||
since they aren’t shared with other codes.

|
||
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
|
||
don’t 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, it’ll check the state within
|
||
the ISR, but can’t 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
|
||
homing limit switches. The homing cycle now applies the max travel of
|
||
each axis to the search target. Generally makes more sense this way and
|
||
saved more than a 100bytes of flash too.

|
||
find the limit switch.
|
||
|
||
- Homing cycle bug fix when not finding the limit switch. It would just

idle before, but now will exit with an alarm.

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
|
||
(doesn’t de-energize the machine) with a ‘@‘ character. If the safety
|
||
door input pin is not enabled, the system can be resumed at any time.

- Added an ‘examples’ directory with an upload .INO sketch to further

|
||
|
||
- Updated the Makefile with regard to the source code no longer being
|

separate ‘build’ directory to keep things tidy. The makefile should
|
||
operate in the same way as it did before.

Subject: Bug fix for certain motions. Re-org of includes.
|
||
|
||
- 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 shouldn’t 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.
|
||
Doesn’t do anything special, just prints the binary for the port. 0’s
|
||
and 1’s indicate low and high signals on the pins. It’s a bit cryptic
|
||
right now, but it’s 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 hasn’t been added to the Grbl settings,
|
||
like the others, and will have to wait until v1.0. But for now, it’s
|

available as a compile-time option in config.h.

Subject: Lot of refactoring for the future. CoreXY support.
|
||
|
||
- Rudimentary CoreXY kinematics support. Didn’t test, but homing and
|
||
feed holds should work. See config.h. Please report successes and
|
||
issues as we find bugs.
|
||
|
||
- G40 (disable cutter comp) is now “supported”. Meaning that Grbl will
|
||
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 Grbl’s 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 wasn’t
|
||
showing up. It now does, along with the other new probing commands.
|
||
|

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.
