My past CNC conversions used stepper motors so were inherently slow.
My latest conversion (8x30 Knee mill) with DFU2005 and DFU1605 ballscrews uses 750W ac servos, These are a world different in terms of torque at speed and I can move the table near silently (compared to steppers) and fast, test run at 100IPM is no problem.
I would imagine the forces at the ballscrews are not trivial. So my question is if I want longevity what are good limits to place on acceleration and velocity?
