By BB controller died. I considered just buying another BB unit, but have decided to go another route. I did pick up a Blackbox control for a laser build, and dont want to use another all in one unit. I have some stepper drives and power supplies. I picked up some inductive sensors and bought a low cost Mach3 USB breakout board. Will be putting this all together sometime after the holidays. I considered Buying hardware and going the Acorn route, which I may still do down the road. But I am familiar with Mach3 & thought this would be my best solution in the short term. Anyone else that has gone the Mach3 route feel free to chime in.
