[new] Added a default configuration for the parking override control
upon a reset or power-up. By default, parking is enabled, but this may
be disabled via a config.h option.
[fix] Parking override control should be checking if the command word
is passed, rather than the value.
[ver] v1.1f update due to tweaks to interface from new parking override
control.
[new] Parking motion override control via new `M56 P0` and `M56 P1`
command, which disables and enables the parking motion, respectively.
Requires ENABLE_PARKING_OVERRIDE_CONTROL and PARKING_ENABLE enabled in
config.h. Primarily for OEMs.
[new] `M56` appears in the $G report when enabled.
[new] Five new build info identification letters. Some were missing and
a couple are new. Updated the CSV and documentation to reflect these
new items.
[new] Spindle enable pin configuration option to alter its behavior
based on how certain lasers work. By default, Grbl treats the enable
pin separately and leaves it on when S is 0. The new option turns the
enable pin on and off with S>0 and S=0. This only is in effect when a
user enables the USE_SPINDLE_DIR_AS_ENABLE_PIN option.
[fix] M4 is now allowed to work when USE_SPINDLE_DIR_AS_ENABLE_PIN is
enabled. Previously this was blocked and was problematic for laser
folks using M4.
[fix] Properly declared system variables as extern. Not sure how that
went unnoticed or why it worked up until now but it has.
[fix] EXTREMELY RARE. When AMASS is intentionally disabled and sent a
motion command that is _one step_ in length, Grbl would not actuate the
step due to numerical round-off. Applied a fix to prevent the round-off
issue.
[fix] Added a compile-time check for AMASS settings to make sure that
the numerical round-off issue doesn’t effect it. This would only happen
if someone set AMASS max levels to zero. It does not effect AMASS with
its current defaults.
[fix] Wrapped the mc_parking_motion() function in an ifdef for porting
purposes.
[fix] Fixed an issue when in inverse time mode and G0’s would require a
F word. This was not correct.
[fix] Added a note in the defaults.h file that MAX_TRAVEL values must
be positive. Some users were setting this negative and it was causing
issues.
- [bug] Fixed a homing fail issue, where the alarm was not being set
right, not cleared correctly. It would report the wrong code and enter
an infinite alarm loop. This was due to how alarm codes were altered a
while back. Now updated and fixed to show the right codes.
- [feature] Re-installed optional software debouncing for hard limit
switches. By request.
- [fix] Spindle PWM minimum value had some typos. Fixed the macros to
compile correctly. Only effects users that enable SPINDLE_MINIMUM_PWM.
The name changed to SPINDLE_PWM_MIN_VALUE for consistency sake.
- Updated the laser documentation.
- [config] Permanently removed classic GUI interface support. This
unintentionally created a problem where some users/GUI devs used this
compatibility mode and did not update to the new interface. So, there
were two interfaces in use, rather than just one like it was intended.
This removal should help everyone by forcing all GUIs to update and
updated GUI not having to support yet another interface.
- Fixed typo with line number support in jog mode.
- [laser] Tested a working version and pushed the wrong one for the
last! 20161203 was pausing upon every spindle speed change. That’s not
right. Fixed so nearly all motions are passed through and does not stop.
- Minimum spindle speed override lower from 50% to 10%. Lasers could
use the lower speeds.
- Fixed a very minor bug related to G80 error checking. Allowed no
error with non-modal motions with axis words. Not correct and fixed.
- Fixed a compile error when disabling VARIABLE_SPINDLE
- [doc] Updated some obsolete documentation.
- [doc] Started a “Laser Mode” document that summarizes how Grbl’s new
laser mode works.
- Increment to v1.1e due to new laser features.
- After several discussions with some prominent laser people, a few
tweaks to the new laser mode has been installed.
- LASER: M3 behaves in a constant power mode.
- LASER: M4 behaves in a dynamic power mode, where the laser power is
automatically adjusted based on how fast Grbl is moving relative to the
programmed feed rate. This is the same as the CONSTANT_POWER_PER_RATE
config.h option in the last version. NOTE: When not in motion in M4,
Grbl automatically turns off the laser. Again, it only operates while
moving!
- LASER: Only G1, G2, and G3 motion modes will turn on the laser. So,
this means that G0, G80 motion modes will always keep the laser
disabled. No matter if M3/M4 are active!
- LASER: A spindle stop override is automatically invoked when a laser
is put in a feed hold. This behavior may be disabled by a config.h
option.
- Lots of little tweaks to the g-code parser to help streamline it a
bit. It should no effect how it operates. Generally just added a parser
flag to track and execute certain scenarios a little more clearly.
- Jog motions now allow line numbers to be passed to it and will be
displayed in the status reports.
- Fixed a CoreXY homing bug.
- Fixed an issue when $13 is changed, WCO isn’t sent immediately.
- Altered how spindle PWM is set in the stepper ISR. Updated on a step
segment basis now. May need to change this back if there are any
oddities from doing this.
- Updated some documentation. Clarified why M0 no longer showing up in
$G and why a `1.` floating point values are shown with no decimals,
like so `1`.
