In building (planning) a plasma table, where is the line at which a stepper is too big. Not considering cost, only performance. I have read a lot about gearing down for torque and not having enough acceleration to make good details, so to me using a 1200oz stepper would be a great idea. but what are the issues with going overkill on the stepper.Is it juts the added weight? Is it harder on the power source/drivers? Maybe it breaks pinion teeth? or is it just the cost that keeps most from using it?
Also I have gotten the impresion that if you have athc, then the accuaracy of the table (flatness) is much less important. is this correct?
Thanks
