Thanks, I am hoping it prints!
I didn’t even think to check Microcenter! If this works out, I will go there and grab some samples rolls!
Thanks!
To successfully print the MakerGeek Raptor PLA on my TAZ 5, I had to modify my hot end with the TAZ 6 hot end 40mm fan to address the heat creep issue. Once the 40mm fan was in place, the Raptor filament printed great. No sticking in the tube or other feed issues. I really like the Raptor material now.
So after much learning in general, I have found something interesting, not just about the Makergeek filament, but filament in general…
After a failed print, where the filament feeds until it grinds and stops, I check to see if the gap between my head and bed are still accurate. If that’s true, I immediately stick my filament in the oven @ 175 for 3 hours.
9:10 times, that fixes everything.
So what’s happening?
Well, the short answer is moister. In the case of the Makergeek filament, it came “wet”. In cases where I have used a filament in my collection successfully, but now having issues, It means I have humidity in my office and not a good solution for keeping my filament dry 
In fact, I just got some samples from Makerbox, and one of the samples was brittle. In the oven, and everything was grand.
I have done this with PLA (mostly) and ABS.
I had a lot of trouble on my TAZ5 with the 3mm Hight Temp PLA as well. Ironically one of the best prints I have ever done on the TAZ was the HT PLA when I tried 1.75mm filament in the TAZ. Yes, the wrong size. Makergeeks sent me the wrong size the first time.
With the right size, jam after jam, I gave up on it. I did a few other prints with the 1.75 though. But…
I found a major issue with my Taz5 which might be affecting you as well. The heat break cooking fan was not moving enough air. The upper end of the extruder is too hot and with retraction, the filament swells a bit when it’s forced back into the nozzle. With the swell, it jams due to the increased diameter.
This applies to all filaments with retraction but maybe HT PLA is a bit more sensitive since it’s printing at a higher temperature.
My cooling was low because I “Upgraded” the cooling fan. After that upgrade, I had so much trouble I went and bought another printer. I upgraded the cooling on the new printer as well. After the “upgrade” on the new printer caused the same problems, it dawned on me. The really great fan I used in the upgrade, while quiet, ball bearing, and advanced, just did not blow enough air.
