CNC hanging up on z retract (for a tab) mid Arc. Trying to see if gcode or controller board… I have run the gcode from 2 different PC’s with same result. file hangs at same line. Gcode in simulation is fine but machine will lock up and not respond to any more commands. TinyG ends up in odd state (pulsing multiple LEDs very slow) and reports as machine alarmed. Gcode is generated by ESTLcam with GRBL post processor selected. Thoughts?
Only thing I can think of first is upgrade to 1.92 SPJS, although truly if your TinyG is blinking like that it got a Gcode command it doesn’t like probably.
I think I was hitting Soft limits - I added a bit of margin from part an re compiled G code and working now.
