- 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.
- Returned the max step rate to 30kHz. The new arc algorithm works uses
so much less CPU overhead, because the segments are longer, that the
planner has no problem computing through them.
- Fixed an issue with the acceleration independence scaling. Should now
work with accelerations above 400mm/sec^2 or so.
- Updated README
- Arc mm_per_segment parameter was removed and replaced with an
arc_tolerance parameter, which scales all arc segments automatically to
radius, such that the line segment error doesn't exceed the tolerance.
Significantly improves arc performance through larger radius arc,
because the segments are much longer and the planner buffer has more to
work with.
- Moved n_arc correction from the settings to config.h. Mathematically
this doesn't need to be a setting anymore, as the default config value
will work for all known CNC applications. The error does not accumulate
as much anymore, since the small angle approximation used by the arc
generation has been updated to a third-order approximation and how the
line segment length scale with radius and tolerance now. Left in
config.h for extraneous circumstances.
- Corrected the st.ramp_count variable (acceleration tick counter) to a
8-bit vs. 32-bit variable. Should make the stepper algorithm just a
touch faster overall.
- Fixed an issue (hopefully) with slow trailing steps after a
triangular velocity profile move. Sets the trapezoid tick cycle counter
to the correct value for an accurate reproduction of the deceleration
curve. Keeps it from arriving too early to the target position, which
causes the slow trailing steps.
- Added Zen Toolworks 7x7 to default settings.
- Updated readme with new edge build.
