Since utilizing your instrumental help to slice the .stl file, I've since had to take apart the extruder and checkout the motherboard to update the firmware and complete the blockage in my extruder. Everything is factory and the motor definitely works, I'm ready to try and print a calibration test plate as per the attached video-- but now Ultimaker Cura refuses to work on my PC for some reason despite multiple reinstallations, PC reboots and temp file cleanups. Could you please assist me in (hopefully) the last hurdle before my first print?
