I shouldn't have said "always near the end" that was meant more tongue in cheek. sorry for that.
The jams can happen anytime so I don't think there is an issue regarding last layers.
I also noticed that the filament guide seems to have bent. but from my perspective that does not seem to be "the issue" here
I open to getting the hobb goblin and that may be what is needed.
so to answer your questions directly
the PTFE tube is a few millimeters (~4 mm) above the "swage" thing that captures it.
I do not have my doodle enclosed as of yet.
I'm guessing that a more aggressive hobbed gear will only eat the plastic in these occasions. I guess I'm saying that I think the filament guide and hobbed gear seem (from my perspective) to be operating within normal
I did not use any heat paste...I'm unsure of where I would have used it. possibly between the nozzle and the heat sink?
I do take the time to tighten the nozzle while hot to assure a good thermal connection. (my engineering degree does come in handy once in a while)
Although I don't have good evidence, the back and forth action that relieves the problem feels to me like the problem is occurring between the hobbed gear and nozzle. either in the Break or the PTFE or the transition.
would you consider a replacement of the PTFE and/or Break to be reasonable avenues? have you seen this problem solved by this type of replacement?
Thank you for the great responses
