I apologize for my horrible sketching skills in advance.
When I printed TPU with the TPU Feed Assist Module (TFAM) for the first time everything worked out great, only when trying to unload the tpu after the print everything went downhill. (I don’t know if the TFAM only gets power over the 4 pin connection), but a warning message to disable the feeding assistance before unloading the TPU would be very nice for beginners. As shown in my sketch, that’s what I imagined happened (having the TFAM keep pushing TPU into the Extruder while the extruder trying to unload), because TPU got tangled in my Printhead. I had to disassemble the whole head to get the tangled TPU out, which took way too long for my liking, which could’ve been avoided through a quick notification or warning. Or even if possible to have an option to automatically disable the feeding mode when finished printing, or even turning on the unloading mode when unloading filament.
Also: Can a Mod please add the firmware-feature tag to my post?
