I seem to have broken the hot end and stepper motor control on my Taz 3 extruder. I have tracked down the hot end malfunction to a fried heat resistor, but I can’t seem to figure out what happened the stepper motor. When I send a command using the move extruder 1mm command on the LCD, nothing happens.
I checked the fuses on the Rambo and they are all in tact. I have tried connecting another stepper motor from my Flexystruder (which I know should work) and it does not move either. All other stepper motors (X,Y,Z) on the Taz 3 work fine.
I’m not sure what to check next; does anyone have an idea of what may be wrong? Are there any electrical connections I can check to troubleshoot this?
