Filament Sensing Calibration failure on Core One
Hi All,
Received a Core One for Xmas and just spent the last 2 days installing the MMU3 unit to it. Although frustrating, everything seemed to go according to the instructions until I reached the step to calibrate the filament again. I followed the steps and put a well cut piece of filament into the chimney on the extruder but it never detects the filament. I feel the filament get grabbed and the internal gears are pulling it in but it never passes calibration.
Would love some advice on what to do here.
