[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.
- [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.
- [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.
