Has anyone has much success printing with PushPlastic’s PLA on a Taz 6? I’ve had nothing but trouble with it. I used the Verbatim PLA .25mm profile as a starting point (and the sample Verbatim PLA printed wonderfully) but nothing I’ve done has been very successful. I always end up with the filament becoming chewed up by the hobbed bolt, and the extrusion stopping. So far I have:
- Adjusted the temps - tried everywhere between 190c and 210c
- Adjusted and re-adjusted the idler tension - started with 8mm between spacers, and adjusted to tighten. Stopped tightening around 5mm because it was just getting too tight.
- Cold pulls - more than I can count.
- Adjusted retraction distance/speed, and also disabled retraction.
- Mounted a higher-flow fan to cool the hot end (two different ones actually, so I’m up to 3 different fans) - and tried the the temp range of 190c-210c (at 5 degree steps) for each fan.
- Tried Printing without guide tube
- Adjusted the z-offset
- Cleaned the hobbed bolt teeth more times than I can count
- Adjusted the print speed - tried 60mm/s, 60mm/s, and 40mm/s
- Tried multiple spools of filament
Also, I’ve printed several successful parts (the same ones that failed) using the ngen sample that came with the printer, and the Verbatim PLA that came with it. And this was between failed PushPlastic PLA prints, so I’m 99% sure it’s not a nozzle blockage.
I hate to give up - because frankly, I’ve had lots of GOOD luck in the past with PushPlastic’s products - I used their PLA almost exclusively on my Printrbot with zero problems. Also, I have 5 brand new spools of it that I’d really like to use, vs. trying to return 3 of them that are still unopened.
Any feedback would be greatly appreciated!
