Decided and ordered.

Its gonna be 4 steppers

4x 4amp 4Nm nema23 All round : cnc4you

Does anybody have a realistic number on power needed for those?

I would like to do a dual diy toroidal transformer setup.

So 2 dual 24v transformers , dual rectifier.
dual 68volt circuit.

1 for dual x motors and
1 for the y and z motor.

Is it as simple as 2x4 Amp stepper, so 8 to 10 Amp 400 to 500VA per transformer?

Or will less power be sufficient?

1 kW sounds like a lot and ott.

I gues not many times all 4 steppers are running full throttle all the time...


Anyone?


Grtz Bert.

Also ... is there such a thing as minimum belt length?
