I bought Velleman PLA and I had problems with the detector thinking the filament ran out. when I tried to insert it again it gets stuck on something in the feeder and doesn’t come out the other end.
If you are looking for help
Maybe try to disable the filament detector or trick it …
You may need to sharpen the tips of the filament like a pencil or take the extruder apart to see if there is an alignment issue or to use conical drill to limit the junctions difficult to cross.
