Had to get a replacement as the stock extruder motor was slipping and my models were failing due to filament jamming..once the new one arrived it was fitted then calibrated to if it was over or under extruding and it turned out to be slightly under. Followed a vidio on youtube ,of which there are many, and the motor has been fine. No slips and no jams. Bought using Klarna. A vital buy. Will be buying another for my spares box
