Hello, we have been printing Polylite PLA with on Lulzbot Taz 5 and Taz 6 and Mini with no issues. It has been a good alternative to ABS.
However, the last batch of Polylite PLA True Black we bought from Core has been a complete disaster. Although the SKU is the same, the filament has a rough surface appearance instead of being shiny. Again, although the SKU is the same, the printing speeds and temperature on the labels are different.
Every time we print, the drive gear simply cuts into the filament at some point and it jams. We have tried temperatures in 5 degree increments from 190C to 230C, have calibrated the z steps and filament drive - all to no avail.
When we put the same material in but True Blue, we have no issues.
