Hello, I am new on this forum but I hope you will able to help me.
I also have problem with A4988. I was running two Z mottors in series and they were working fine for a couple of minutes. Then both just started vibrating. I checked voltage on output pins when motors were iddle and there are 3 pins with over 12 volts and single pin with only 2.8V. The current on this pin is also much lower. Has anybody encountered similar problem and is it possible that A4988 just burned?
I tested this stepstick with single motor earlier and it was working pretty well.
Sorry for my english and thanks for any help!
