Duet3D_6HC_How to redefine M3 (m code) function?

jimmychiu

I want to change M3 function to run M118 S"XXXX" to run BLDC drive.
Is it possible?

Two options:

Modify the firmware source to do that.
Use a GCode post-processor to replace M3 commands either directly by that M118 command, or by a macro call that can then be defined to send that command.

In future I may prove a facility to flag particular commands to call macros, but that will be much more useful when macro parameters have been implemented.
