I'm in the process of Building a rotary axis, so my thinking is to use a large stepper motor nema 34. I'm thinking of driving the motor via a 10 micro stepping Gecko as I've had good results on my router motors. I'm re-using a manual table indexer,
My questions are:
What torque motor do I need?
Do I need a brake or will the holding torque of the motor be enough?
If a brake is needed what do you recommend?
Whats the ideal gear ratio or is it min angle per step?
Anybody who can help or has been there and built one your information would be gratefully received.
Kind regards
