these things are supposed to be the bee's knees for shop vacs. there are some pre-built kits and some DIY type plans. a guy who can put a CNC laser engraver together should be able to figure it out

Hello Yuri,
I have a similar project... well ok sort of similar, Monarch 10e-nc with dead controls. have every thing I needed to get it together but looking at the break out board I orders is is limited to 10 khz. (i really wanted and optical isolated bb) I'm thinking that is not fast enough for step and direction to the gecko drives. I was original planning to go Mach3 EMC => parallel port=> breakout board=> gecko drives

How did you do yours? The breakout board is simple enough that i could replace the slow optos with faster ones on the step and dir channels.

That's essentially how mine is set up. I use a C32 breakout board from CNC4PC and Keling's digital drivers. I really like the drivers, but the C32 board is perhaps not the best if you're using true parallel ports rather than the USB Smoothstepper board. There are some weird voltage issues that I'm working with Arturo of CNC4PC to solve. I wanted maximum flexibility, but I have (as usual) overcomplicated things by using a board with so many additional features.

I'm almost positive that Geckodrives are already opto isolated. You're duplicating effort to isolate step/dir on the breakout board.
