Hi, we use Arduino UNO to control 2 stepper motors used for rotation at a crystal growth machine. we use another Arduino UNO for a third stepper motor used for a pulling operation in the same machine.
The motors operation shows to be very unstable - when changing parameters such as rotation direction or speed or starting the third motor they stop working, sometimes the program sticks too. till now we don't know why it is not working properly and how to fix it.
