Firmware settings using Gcode.

[infamous-panda]

Is there a way to change GRBL firmware settings within a Gcode program? An example would be a job using both a router and laser engraver where $32 laser mode can be changed mid job. Also interested in changing acceleration values for specific jobs.

Iosender seems to ignore $ commands in Gcode. Is this a firmware or sender limitation?

I would like to second a M-Code to switch between laser and Spindle. Setting $32=1 is a flash write and I would prefer to limit what my "Default Config" is and just switch between laser mode and spindle mode

It is a sender limitation. Perhaps I should allow $ commands, I have to think about that as $ commands in gcode programs may result in an error beeing raised.

Does LinuxCNC have a definition for one? I am not too keen to add non-standard M-codes to the core, but adding them to plugin code is ok.

Please note that this repo is going to be archived soon.

A mini plugin for switching between Modbus VDF spindle and PWM output has been added to the Spindle plugin, currently it uses M104 to switch between them: M104P0 for PWM (laser) and M104P1 for VFD.
Available when #define DUAL_SPINDLE is uncommented in my_machine.h for drivers that has support,

Also interested in changing acceleration values for specific jobs.

The OpenPNP plugin adds a M-code for that.
