Yeah. I guess I'm missing something. Rack and pinion is good for linear motion, but what is keeping it in a straight line as it's moving at 100 IPM with the attached Y axis simultaneously throwing a cutting spindle back and forth. Also, what stops the machine lifting off the rack as you plunge a 1/2" cutter into your material.
I'm not trying to run your idea down. I'm merely pointing out the fact that rack and pinion drive will still need some kind of linear guide.
If I've missed something, then perhaps a picture or drawing of your idea would be of benefit.
I, like many others on here, have been looking for a cheap linear guide system. So far the pipe and skate bearing combo looks about the most reasonable "cheap" system. I'm working on a design, based along the lines of the pipe and skate bearing combo. Still a little way to go with it, but it's looking good so far.
