Help select Servo type, conversion from steppers.

[fabhund]

So how will servo's help this problem.!. . I don't understand your logic.? They will if anything make it worse as they spin much faster and don't like resonance which affects the tuning.

Dear Sir. Thank you for your feedback.

The vibration is not coming from the rotation itself but from the steppermotor steps. Especially in low rpm feeds 50-300mm/min. So my logic was to have a "step-less" motor to get a smooter rotation motion.

I'm aware of the problem with MACH3 pulse speed and the quality of the pulses. Currently I'm running 25kHz with good results.
So a ESS smooth stepper (or similar) is a must for servos.

Right now MACH3 is set up to 80 steps/mm (and depending on ballsrew lead that is 800-3200 steps/rev)

So I guess I could invest in an external motion controller, and increase the microsteps, and increase the steps/per. And that might give an overall smooter operation, without loosing speed ?
