Hi,
i baught a bunch of polysmooth ( http://www.polymaker.com/shop/polysmoothpolysher/ ) filament to use on my upBox printer. But i have been struggling to print this filament. My print head constantly jam under 0.3 ... I have tried different temperatures between 210 and 230 and speeds without results. Iam not really sure what to do next. Did anyone ever print this filament ?
The new upbox software support alternative filament options, it easy to add new ones but do i need to upgrade the firmware inside the 3d printer as well ?

From my experience, the best option for Up Box is using Tiertime materials. I also use some of the Zortrax materials - UltraT range, but I am afraid to put anything else inside it because bad things happened when I did that. :)

I did print polysmooth on the up mini 2, not on the up box yet as it's under revision.
It printed well, no clogs or jams/extruder clicking however... i printed without the top covers.

Even had a 10h print going without any issues at 0.2 layer height.

Try to print this again with the top cover open and fan open as well. This should let you print with polysmooth.
Also make sure that your nozzle is not too close to the print bed. If you have it too close, it will struggle to push it out and bad things happen because we can't control retraction/filament density and other settings.

Thanks kertman!
May I ask, what temperature and speed did you use on the up mini?

As kerstman said, with "low" temperature extusion filaments I would open the top cover to avoid clogs.
(I think this is because the filament in its way to the extruder becomes softer and the extuder cannot push it properly.)

I found it prints best for me at 214 for the nozzle with normal and fine speeds.
