I'm running a PID loop in HAL to control the temperature (and a few other things like fan speed). I need to be able to update the set values via gcode with minimal impact on overall motion. I'm hoping the G67 works better than M1xx codes, but haven't tested it yet. -- Charles Steinkuehler [email protected]
