I am building a camera slider that is powered by a Stepper with Arduino Nano and A4988 driver. Everything works. But, somehow there is a loose connection in the breadboard. Sometimes the stepper stops, and for a long time it drew very little current and the stepper had almost zero torque.
- Could the low torque be caused by a bad connection?
- Is Breadboard known for beeing unrealiable?
- Am I doing something wrong? This is the second time this happened with steppers and drivers and I used two different breadboards.
- Please cheer me up. Troubleshoothing sucks with random behaviour.
