After using the XY plotter for a while, I ran into a weird issue. It looks like one of the stepper motor drivers has broken. When plugged into the board, its power LED blinks at a steady clip. It does not turn solid and does not respond to any input from the software.
When it is plugged in, it seems to prevent the other stepper driver from initializing as well. When unplugged, the other stepper driver turns solid and acts as normal. I’ve tried swapping out the cables, plug ports, and connected stepper motors, but the issue seems to be located within this stepper driver itself. Any advice? Maybe I need a replacement, but they’re like $20 apiece? That’s kinda steep.
