I have been having feed issues with my Taz 5.
If my prints are smaller, say 15 hours or less it prints just fine. While printing larger prints, up over 20 hours I keep getting feed jams, I would say about 75 % of the time.
While browsing the forum I have read about heat creep in the filament.
I am printing PLA, I was printing at 210°, I need the higher temp for my first layer. I started lowering the temp after the first layer, I am down to 195° now.
It seems like I have gained a few hours but still having the issue. The filament checks good on diameter, .112" ( 2.84 MM ) all the way down the filament, past the hobbed bolt in into the print head, except for the last .250" or so, the material is swelled up to .120" ( 3.048MM ) It is swelled up large enough that it is difficult to pill the filament out of the extruder. I am debating taking the extruder apart and opening the through hole up .002 - .004 and see if that helps, but that’s a last resort.
So far I have had the issue using IC3D and Gizmo Dorks. According to Lulzbot tech these are crappy filaments, my problem is, this is all I can find. I buy from Amazon, everything in black is out of stock.
Filament size, Lulzbot reccomends 2.85MM Ø, everything I find says 3MM ± .01MM except for a select few that are 2.85MM, Gizmo Dorks being one of those. SO my question is, what is everybody else using and where do you get your filament?
