Deforming Teflon Sleeve
We have about 7 Mk3s pre-assembled printers bought at the end of 2019 and are using PLA material with pre-set settings from the list. We are having a regular fault on all machines where the teflon tube is deforming. The tube is shortened and a ring or flange is formed around the tube. The tube compresses down onto the filament and it won't withdraw. The teflon must be too hot and is softening but we are using standard settings.
Good morning Don,
do you have pictures of this issue?
