PWM connected to Arduino UNO (B) to control motorspeed of BLDC motor. Voltage 0-5VDC. A separate Arduino UNO (A) is programmed to power a stepmotor NEMO17 via a driver. At a >50% PWM the rotation of the stepper becomes irregular. What is the cause of the unwished induction or voltage leaking?
Details of the installation, including full codes and cicuit are published at Hackster.io visible via key words : fruit, pitting, 2021
Help to taggle this final problem will be appreciated
Problem solved: Both USB sticks connected on one source; PWM can go to 100%
Stepper motors are not controlled using PWM. Stepper motor drivers need to receive a train of step pulses at suitable intervals with a pulse width of about 10 microsecs. The interval between the pulses determines the speed.

Anyhow, many thanks for your swift reply.

Sorry. But I have no intention of going to that much trouble. I will give my limited time to other people with questions who have provided their information here.
