- Re-organized source code files into a ‘grbl’ directory to lessen one
step in compiling Grbl through the Arduino IDE.
- Added an ‘examples’ directory with an upload .INO sketch to further
simplify compiling and uploading Grbl via the Arduino IDE.
- Updated the Makefile with regard to the source code no longer being
in the root directory. All files generated by compiling is placed in a
separate ‘build’ directory to keep things tidy. The makefile should
operate in the same way as it did before.
- 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.
- 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.
