3D Chameleon too tight. My Neptune 3 pro extruder cannot pull the filament with enough force.
Hi all. I just purchased a 3D chameleon mk4 and I am having a bit of trouble getting it setup. The chameleon works properly when it comes to unloading and loading filament by clicking the switch but my Neptune 3 extruder does not have enough power to pull the filament. Therefore my printer essentially runs out of filament. I even tried manually pulling the filament and it takes quite a bit of force, but it does move. Any ideas what is going on?

Hey Bill. Firstly I am shortening the PFTE tubes as it was longer than I needed. Will be testing that shortly. While manually testing inserting the filament by hand I noticed that more force is required to move some filament than others. Specifically T0 is fairly tight while T4 can move fairly easily. Both still will move through the chameleon and tubes but T0 required significantly more force. Would this indicate a misaligned cam? Is there supposed to be no resistance at all or is this normal? Thank you for your help.
