May be there is some information about this problem, but I can’t find it.
So, I try to use this Sketch, but have problems with the motors movement.
When the power supply to the motors is ON, they stay calm.
When I power on the arduino, the first motor starts to “pulsing”… It stays on place, but when I take it in hand I can feel its pulsing - every second.
The sketch have test (go home) movement for both motors. The first ones moves steps by steps (a couple of steps every time), the second one moves almost smoothly.
I believe that something in the sketch (or in the libraries) is wrong, but have not enough knowliges to find the problem.
The guy that have published this sketch do not respond.
I hope, someone will help me.
