Has anyone had issues printing Silk PLA? I am having a really difficult time printing Silk Rose Red 1.75 mm PLA filament by CC3D ZHUOPU. Seems to work better with the hotend at higher temperatures, say 239 deg. A print will start absolutely fine then... then out of no where start to become stringy and will catch and destroy the print. The only change I can think of is the fan speed increases automatically because of hotend temperature the further into the print.
