Thanks very much for the input guys.

Looks like the ideal is servos for heavier machines. Been looking at the extra cost to set myself up with these as opposed to just getting a couple of bigger steppers, and I'm looking at 4 or 5 times the price. Gearboxes, new drives, power supply, etc get added to the equation.

SO my question now is does anyone know if dual 1200 oz steppers would suffice for a gantry weighing up to 200 lb and give the required acceleration and speed for plasma cutting. Reduction ratio of 1 stepper revolution = 1 inch of gantry travel.

Thanks,

Keith.
