FLEX TPU wont load through extrder. What is needed to get to load.
When TPU tries to load extruder chatters and won't push material through tip. Is there an adjustment i need to make?

When the printer brings up the selection dialog for filament type after detecting the filament, try selecting "PLA" as type. This worked for several TPU/TPE filaments on my MK4S. My guess is that the nozzle temp on the selection "FLEX" on the printer is too high, the filament will get too soft and the extruder will skip. Just select "PLA" and the printer will load the filament without skipping. This had no negative effect on my prints and did not cause any warnings because of wrong filament type afterwards on my printer.
