Thank you for the reply ! Was getting really lonely in here all alone.

In the posts above I mentioned replacing the PTFE tube in the malfunctioning extruder with a brand new one but that did help.

Still....nice to have a reply

I feel your loneliness. diy forums all over the place seem to be dying . Unfortunately, I don't have the knowledge required to help you with your problem.

Although I doubt it's the stepper motor, and if you think it is, the obvious thing is to switch it with the other motor and see what happens. Then try swapping the drivers to see what happens. What would the filament cost be to run those tests? 3 to 4 hours into it, wow. Such a random thing.

I don't own a filament printer, so like I said, I don't have this specific knowledge to help you. What does a new print head cost?
