I’m new to 3D printing, playing around with a TAZ 5 with a FlexyDually. (Yes, I know, not the best setup for someone who’s new - but I’m figuring it out, slowly!) I’ve been doing some simple test prints, experimenting with Lulzbot’s stock filament profiles and a few different materials. Test prints with ABS and HIPS show some minor issues as far as curling or warping, but at a basic level everything is functioning fine. However, I’m having a persistent issue with PLA when I try to do the same sort of test prints.
When I feed PLA into the extuder, I have no problem pushing it through the nozzle at the recommended temperature (205), so I don’t think the nozzle is clogged. But no matter how I set the tension, after a few successful test extrusions it either stops feeding, or slows to a very slow feed rate. I keep pulling the filament out, cutting the melted/chewed end, clearing the nozzle, and trying again with slightly more or less tension (or slightly lower or higher temperatures), and I end up with the exact same result every time.
I’m giving up for now, and when I have time I think I’ll start my next round of tests by pulling the PLA out and trying another ABS print, just to see if the problem persists with other filaments. But in the meantime, has anyone encountered this? Is there anything I should try when I go back to working with PLA?
Edited to add: I’m using the standard head on the FlexyDually, not the FlexyStruder.
