Hi CNC Group;
It's been a few years since I last worked with my steppers and drivers, but I'd like to get back into it. One thing that's changed in that time, is that USB ports are used extensively now, as opposed to the parallel port (do current computers even have these old ports?).
I have a parallel port breakout board, but now I need a decent 4 axis breakout board, USB connected. I will be running a hobby-sized vertical milling machine with a rotary table and using 200 steps/rev. motors of roughly 450 oz-inch. My drivers are from Dan Mauch's Camtronics, the solder-it-yourself-kit, but if those don't prove to be stable, I'll just replace them with Gecko's.
I'll likely go with Art's Mach 3. I haven't done it yet, but I assume that Rhino 3D models can be converted to code for 3 or 4 axis machining? I'd like to stay with Rhino, since I've gotten pretty comfy with it. In fact, I am totally impressed with Rhino and its user-friendliness.
So, back to my subject, assuming that breakout boards can be connected via the USB port, what one would you suggest for my needs?
Thanks for any help, Tom.
