I'm very new to all of this and I need help figuring out what's wrong with my stepper motor control setup. I've been trying to adjust the current limit on my drivers, but I've been having some trouble. I'm not sure if my difficulty measuring the current limit is an issue with the physical setup of the board or maybe the multimeter itself. After the last adjustment I made, my stepper motor started whirring, but without moving. Any idea why this could be? How can I tell if the wires connecting the board to the motor are oriented correctly?
I'd also appreciate any tips for the setup generally.
I keep having problems with the drivers overheating. How can I tell if any of the components have been damaged by this, tell what's causing this, and prevent it?
A simple solution is to use a fan directed at the stepper drivers.
Unfortunately these small stepper modules don't provide a great thermal solution, and if you run them at the max current limit will likely overheat. Certainly if you have them in an enclosure and run them for a prolonged period you will benefit from some forced air cooling.
Most of the drivers seem to have an internal thermal cutoff, but it may not protect them in all cases. If they are damaged, they probably will just not drive the motor.
