Hi I'm new here and looking at building my own CNC... my problem is I'm on a Mac and there is no software out there it seems.... SO.. in my search for a solution I have come across a USB controller that will handle 4 stepper motors.. I think it was just recently developed and sells for about $75 it accpets code from alot.. and I mean alot of programming options including action script from flash.... which BTW lets you create graphics in 3D I will post a lonk to have alook at...but here are some of the specs... can someone tell me if I've stumbled upon something good here,,,,or if I'm just chasing rainbows...keep in mind I know just the newbie basics about DIY CNC's I'll keep my fingers crossed...lol
