- Spindle speed updating wasn’t working in the g-code parser due to
some borked up logic on my part. Fixed it and should be operating as
intended for both normal and laser spindle modes.
- Elaborated a little more on the new sleep mode in the documentation.
- New $SLP sleep mode that will disable spindle, coolant, and stepper
enable pins. Allows users to disable their steppers without having to
alter their settings. A reset is required to exit and re-initializes in
alarm state.
- Laser mode wasn’t updating the spindle PWM correctly (effected
spindle speed overrides) and not checking for modal states either.
Fixed both issues.
- While in laser mode, parking motions are ignored, since the power off
delay with the retract motion would burn the material. It will just
turn off and not move. A restore immediately powers up and resumes. No
delays.
- Changing rpm max and min settings did not update the spindle PWM
calculations. Now fixed.
- Increased default planner buffer from 16 to 17 block. It seems to be
stable, but need to monitor this carefully.
- Removed software debounce routine for limit pins. Obsolete.
- Fixed a couple parking motion bugs. One related to restoring
incorrectly and the other the parking rate wasn’t compatible with the
planner structs.
- Fixed a bug caused by refactoring the critical alarms in a recent
push. Soft limits weren’t invoking a critical alarm.
- Updated the documentation with the new sleep feature and added some
more details to the change summary.
- Increment to v1.1b due to status report tweak.
- Tweaked the buffer state status reports to show bytes and blocks
available, rather than in use. This does not require knowing the buffer
sizes beforehand. It’s implicit.
- Also, since buffer states are not used by most devs (after
inquiries), it is no longer enabled by default and a status mask option
was added for this.
- Fixed some typos and updated for the report tweak in the
documentation.
- Wrote a joystick implementation concept in the jogging markdown
document. Outlines how to get a low-latency feel to a joystick (and
other input devices).
- Removed XON/XOFF support. It’s not used by anyone because of its
inherent problems. Remains in older versions for reference.
- Added a compile option on how to handle the probe position during a
check mode.
- Fixed a jogging bug. If G93 is the modal state before a jogging
motion, the feed rate did not get calculated correctly. Fixed the issue.
- Refactored some code to save another 160+ bytes. Included an improved
float vector comparison macro and reducing a few large and repetitive
function calls.
- Fixed a probing bug (existing in v0.9 too) where the target positions
were not set correct and error handling was improper.
- Reverted back the serial RX count function to how it was. The
variable type was unsigned and cause an integer underflow whenever the
calculation produced a negative number. The old way was the correct way.
- Lots of minor edits to the code CSVs and markdown documents.
- Expanded on explaining feedback messages and startup line execution
feedback.
- Created a new settings codes CSV to help GUIs import the values and
meanings.
- Incremented to v1.1a, rather than keep 1.0e. This is because there
are existing v1.0 installations. Don’t want to confuse people further.
- Certain version of the Arduino IDE did not like the `inline` in the
function header. Removed from spindle_control files to fix the problem.
- Tweaked the communication protocol slightly. Added message type
indicators for all `[]`bracketed feedback messages. It’s been
problematic for GUI dev to try to determine the context of a message
and how it should be handled. These indictors should help tremendously
to remove context all together.
- Also altered how `$N` startup lines are presented when executed. They
now start with an open chevron ‘>’ followed by the line and an ‘:ok’ to
indicate it executed. The ‘ok’ is on the same line intentionally so it
doesn’t mess up a streaming protocol counter.
- Managed to save a 100+KB from refactoring parts of report.c. (Thanks
Vasilis!) Freed up room to alter the protocol a little.
- Wrote a markdown document on interface messaging to make it clear how
it’s intended to work. See interface.md in /doc/markdown
- Started to pull in some Wiki pages from the old grbl site and
beginning to update them for v1.1.
- Created new commit log for v1.1.
