Hi Railroader,

thanks for the reply.

I am using this one: [350 Watt 48 V 7.3A 115/230 V Schaltnetzteil Schrittmotor CNC Router Kits - S-350-48 STEPPERONLINE (omc-stepperonline.com)](https://www.omc-stepperonline.com/de/350-watt-48-v-7-3a-115-230-v-schaltnetzteil-schrittmotor-cnc-router-kits-s-350-48)

I measured the voltage which is exactly 48 V.

The needed torque I have to get of this motor would be 6 Nm with a speed of 150 1/min.  
P = 2 \* Pi \* M \* n = 94,25 W. So the Motor (in theory) would need 1,96 A. The measured ampere is 1.526 A. (Please correct me if I am wrong). But I didn't apply the torque on testing. So this is the ampere without load

But as mentioned, on the Arduino Uno the motor is way smoother than on the ESP. Any Idea on that?

Best regards,  
Daniel
