This was my first project that required crimping and I followed some random video tutorials. I'll definitely redo all the connectors at some point. The other 5 drivers work just fine and I've swapped around all of the connections though, so it doesn't seem like my poor craftsmanship is the culprit.
I tossed the fuse away after putting in a new one, but the internal metal piece was in 2 pieces after the sudden shutdown. If it is a short, it doesn't seem to be in my motor or my connectors since they all work fine on the other drivers.
The board was purchased from Filastruder on 01/19/2021.

New Mainboard 6HC replacing a standard old cartesian FDM board. Before printing I verified every stepper connection and tested individual motor movement and it all seemed fine. During my first calibration print though, the error "Motor Phase A/B disconnected on driver 5" popped up before the 15A fuse triggered. I replaced the fuse and everything seems fine, except the same error is still there when I try to test stepper driver 5 (an extruder motor)
I've tested the original motor and wire on another driver and it works fine. I've tested a different motor of the same model as well as a different connector on driver 5 and get the same error so I have ruled out my motor and wire connector.
As a temporary fix I've just swapped the extruder on stepper driver 5 with the extruder on driver 4. Seems to work just fine, no errors so far.
I suspect the driver 5 might have been damaged during that first print, but I would like to see if there is anything I can test other than hardware just in case I am making some error.
Just curious what the original mini blade fuses are on the 6hc mainboard. Mine fried during a printjob after popping up the error of "Motor Phase A disconnected on driver 5" (as well as Phase B). I'd prefer not to cheap out on fuses (low QA fuses from amazon or alibaba) considering I'm using 24V power. Or if anyone has replacement fuses that have worked well for them.
I also am concerned I may have blown the stepper driver but am unsure of how to test that without a new fuse in hand. Nothing visually is off about the stepper driver but doesn't hurt to be certain.
