I have a Ramps board laying around and I can always borrow the Mega from my Prusa i3 so it’s not too bad. I’ll use my existing stepper drivers too. It is a bummer but I shouldn’t blame my motion controller board .I’ve been reading and now realize that mach3 has a delay built in to the spindle commands. There’s no practical workaround either.Very disappointing to see commercial software that’ s less flexible than open source. On the bright side, I’ll be able to document all of this in a nice walkthrough guide for a $100 laser option.
