I installed a K8203 extruder, which went well.
However, when I try to print, the extruder motor makes clicking noises, the filament moves up and down, but nothing is extruded. When I manually heat up the extruder, I can push filament through the extruder.
I worked exactly according the manual, cut an exact 23 mm of the white tubing, uploaded the new firmware, and installed (and checked) the new Slicer configuration file. I checked the voltage on the driver, which is 0.896 V, which should be OK
Whatever I try, the extruder is simply not feeding, only moving filament up/down?
Could it be that the spring is too tight? I can hardly squeeze the spring handle manually?
Any help would be appreciated.
