Recently built simucube system was working fine. I took it apart this weekend as I was taking measurements to design an enclosure, I also opened the back to replace a 3d printed shaft adapter on my encoder with a metal one. When I turned on the simucube system, it started spinning extremely quickly, it snapped my corded usb cable right off. After about 5 seconds it stopped and I found Fault ID: 140403. I cleared the fault and restarted the simucube and it happened again, except it spins for like half a second now. It says to lower FEV in the wiki but I think my issue is that my wheel just starts spinning immediately. What would cause something like this?
