Edit: Added a video of the problem: I just lost an entire weekend trying to get this thing working, and I'm at the end of my rope. My brand new Hemera heats up just fine and is capable of melting manually pushed filament, but when I start a print or use pronterface to extude for me, the gearbox produces a grinding/vibrating sound and I can see the gears moving but not fully rotating. I've tensioned my extruder arm to the recommended alignment, tuned my PID settings, and adjusted the current to my extruder stepper motor. I've done everything that Teaching Tech did in his Hemera Setup video: Couple of notes, when I went to adjust the current to the Hemera's extruder stepper motor, I found the board was outputting 1.8V when I first tested it, way above the recommended .48V. Could this have damaged anything in the Hemera? Secondly, I found someone else on these forums who had similar looking/sounding issue caused by a miswired extruder stepper motor cable (Blue/green were swapped), but I don't think my board has that configuration because I'm using the same Creality v1.1.4 Silent Mainboard as Teaching Tech. Is there any way to rule that out?
You are right, my blue and green cables were swapped, the diagram on the tutorial video I watched was incorrect. Thanks for your reply.
