Hi!
I am thinking of making a gantry for plasma cutting. I will probably use something like Bosch Rexroth modular aluminium frame for the travelling sections. I understand the difference between steppers and servos, and will most likely be using servos to achieve a more dynamic movement on thinner materials. However, I would like to ask for your advice on choosing a motion system however. The table will be designed to take standard sheet metal sizes, which means that a travel of approximately 1.5m by 2.5m is required. With the gantry being made from inherently light materials and only spanning 1.5m, it shouldn't weigh very much at all. As I see it, I have a few options available. Lead screws, timing belts or rack and pinion. I imagine lead screws are the first to go, but what would you recommend I look at for the drive topology?
