I recently assembled and began testing my MMU3 on my CoreOne, on the first print it ran great for about 2 hours but eventually the filament began getting stuck on the unloads. I have read through many of the help sections on MMU3s and have tried a few fixes but nothing seems to help so far. Any suggestions? I checked idler screw tension and the tension of the screws on the MMU3 and matched them to the assmebly instructions
