So I've had my printer for several years, worked great and has been an absolute work horse. But after many years something finally gave way. The stepper for the extruder was cogging. First thought was a jam, but it was clean and clear. Ran through a few troubleshooting things and found the motor had seemed to give out. New stepper everything SEEMED to be okay. Ran a few small test prints, all was good. Calibration cube and got everything calibrated and locked in. Now the problems started, new stepper started to skip from time to time. Printer began shutting off, giving me the error message that the temp dropped too low and extruder was shut off. I put in a new heater core, as it was old as well and could have gone bad. Happened again. Thought the garage was maybe just too cold so I moved the printer inside. Same error, during first layer of the print. I've looked into a few options, and was wondering if this could be an issue with the RAMPS or a Power supply issue. I've turned here in the past and got my issue resolved within 24 hours. So I'm hoping someone can help me out again.
