Hello,
I tried printing with a spool of PP recently on a UM3, current cura version, and had no luck. It turned to silly string. I tried changing the temperature, flow, speed, etc but no success. The first layer adheres well, but it seems as though it just doesn't extrude enough after layer 1. There is no clog however, and other materials work fine.
Any suggestions? That stupid spool is $70 down the toilet otherwise.
Thanks,
Tiger
