My extruder stepper motor is “vibrating” (twitching back/forth). When applying pressure to the extruder, I can turn it either way physically when “moving” filament.
I have been using a Bondtech extruder with a MicroSwiss all-metal upgrade (which exponentially helped my prints)…but as of a couple nights ago, it stopped extruding. I hoped for a jam, but the motor doesn’t move even when not connected to the extruder. See gif: http://imgur.com/a/SNUy6an
I visually inspected the driver (seems fine), and the wiring (also seems fine). I am scared to test with a multimeter, as I read you can inadvertently fry the driver by testing. Also, the Maker Ultimate doesn’t have adjustments on the drivers, only a single voltage adjustment on the power supply.
Is there any hope outside of a new mainboard for my printer?
