- Cleaned up and organized pin mapping concept by @elmom.
- pin_map.h allows for user-supplied pin mapping and port vector
definitions in a centralized file. With more processor types, more
definitions could be added.
- **NON-FUNCTIONAL**
- Contains an old draft of separating the stepper driver direct access
to the planner buffer. This is designed to keep the stepper and planner
modules independent and prevent overwriting or other complications. In
this way, feedrate override should be able to be installed as well.
- A number of planner optimizations are installed too.
- Not sure where the bugs are. Either in the new planner optimizations,
new stepper module updates, or in both. Or it just could be that the
Arduino AVR is choking with the new things it has to do.
- Increased g-code parser line buffer from 50 to 70 characters. Should
fix most all issues with long arc statements, provided that they are 8
digits(float) long only.
- Added a line buffer overflow feedback error to let the user know when
it encounters this problem. Resets the line whenever this occurs.
(Thanks @BHSPitMonkey!)
- Increased g-code parser line buffer to 70 characters (from 50) to
prevent some long arc commands from getting truncated.
- Decreased planner buffer from 18 to 17 blocks to free up memory for
line buffer.
- Added a line buffer overflow feedback error (Thanks @BHSPitMonkey!)
- WARNING: Completely untested. Will later when there is time. Settings
WILL be overwritten, as there are new settings.
- Soft limits installed. Homing must be enabled for soft limits to work
correctly. Errors out much like a hard limit, locking out everything
and bringing up the alarm mode. Only difference is it forces a feed
hold before doing so. Position is not lost.
- IMPORTANT: Homing had to be updated so that soft limits work better
with less CPU overhead. When homing completes, all axes are assumed to
exist in negative space. If your limit switch is other side, the homing
cycle with set this axis location to the max travel value, rather than
zero.
- Update mc_line() to accept an array, rather than individual variables.
- Added an mc_auto_cycle_start() function handle this feature.
Organization only.
-
Removed inline from all functions.
If this is really needed is there another way that we can get
around using it? (The Arduino IDE does not recognize it)
- Changed up mc_line to accept an array rather than individual x,y,z
coordinates. Makes some of the position data handling more effective,
especially for a 4th-axis later on.
- Changed up some soft limits variable names.
These changes include a path separator fix and the removal of --gc-sections which causes ld failures, and is not needed on a pc.
This patch also changes how a compiler is selected. The makefile will now select the system compiler , which should work fine
under mingw and linux.
