What could cause the the laser to fire using the fire button but with the same power setting it doesn’t fire when started (iE starting a cut / engrave). I can see the PWM pulses on a oscope and there exactly the same amplitude and width if using fire button on the move screen or running from start.
It acts like a hardware issue but I can’t seem to be able to track it down. Yes the Output and show are both on. I noticed that this dose not seem to be all the time but intermittent. Resetting the controller and / or restarting lightburn sometimes fixes it.
This may or may not be related but in device settings on the additional settings tab if I read from controller i get 16.7 for x and y mm/sec> where does that come from? It’s not in any of my GRBL settings. BTW I’m using GRBL 1.1 - LPC for 32 bit controller.
Thanks
