Hello, I currently have an openbuilds "mill" which was slightly upgraded with new table and was added y2 slave c-beam and motor, it now runs 2 separate leadscrews driving Y table. I want to go back and use a single motor and ballscrew and move it with a 4.2A 23he45-4204s motor which I happen to have, anti backlash nut is not my favourite solution to be honest. Would it be too much for one driver? Can I connect the y and y2 outputs to a single motor to move it and give it extra juice so it wont overheat if it will ? I run machine sometimes for 4-8 hours a day with some pauses. As far as I could find it's up to 4A peaks per driver ? I can see that I can go external driver route connecting to pins but for now I would probably just jump to 3a motor if 4.2a is too much.
Depends on all the electrical and mechanical specs, but essentially the 4.2A rating is the motor's "MAX" (the don't give the motor any more than that, the coils will melt) not the recommended setting anyway. Whether running that motor at a setpoint of say 2.8A will deliver the torque the mechanics needs, is the real question. No you can't use two drivers to feed one motor. Motor inductance and resistance (voltage) are more telling of how they'll feel (3-6v coil rating - higher will feel slow on acceleration, and 1-2mH of inductance, much higher will limit top speed) A single leadscrew is almost always more troublesome mechanically than dual Y's (racking and other issues)
