Well I was very excited to get my laser hooked up to my MPCNC after seeing some of the nice work being done here but I’ve had a major setback. I finally got my housing design tweaked to where I wanted it, re-tuned my driver and was very happy to get a hint of that burning wood smell that I had been missing, I’m now learning that the USB motion controller that I have is great for wood work and camera intergration but sucks for driving a laser.

I only have one variable output and it’s for driving a VFD spindle which is fine but the problem is a one second delay every time my M03 command is sent with a different S parameter. Obviously this is a deal breaker. I guess I’ll be joining the Marlin / Ramps crowd in the next few days. Watch this heartbreaking video and feel my pain.
