Drive Systems for Dummies (eg. me!)
OK, so i've been doing a bit of reading and can't really get my head around why one drive system is better than another.To put things in context I am looking at building a oxy/acet table to cut a sheet approx 900x1200.
Firstly i'll start on the gantry. Initially I thought a rack & pinion would be good way to go, but I am sure I read somewhere that this will be a bit noisy. Is that true? I watched Apple's test run of the road runner print and it didn't seem that noisy to me. But what about belt drives? Assuming I can come up with a design that protects the belt from slag during cutting is there anything else to consider? How do they compare in terms of cost & accuracy?
Cheers,
