    This problem began with loud grinding noise and the stepper motor spitting out bad prints. So first i made sure there wasnt any clogged filament anywhere... and tried it again, only to get the same results. So then i figured it must be the stepper motor wires cause one came loose. So i ordered the wires and replaced them and tried another print. Getting same result. So finally i figured it was the stepper motor ( the one behind the extruder, not the ones to the x, and y axis on the side of the printer) so i ordered one. I thought i had it figured out which one to buy, but when it arrived they had sent me a stepper motor for the x, and y axis. I even tried to use the new one thinking it might work, but it wont allow the little gear (cog) to connect. I need the bigger stepper motor. I also know its broken because after taking it off and attaching the little gear to it, it wont turn without a lot of force. The brand new one (although its the wrong one) spins freely by hand. So can someone tell which stepper motor (FOR THE EXTRUDER) i need to buy and where i can find it, and most importantly what is it called??

    Please help!

    I bought these and they're fantastic. Only problem is it only has a single flat on the motor shaft, so the stock gear won't fit. So I went on thingiverse and printed up new herringbone gears with my other printer.

    Just calibrate the extruder when you do replace the motor and you are good.
