I have an ender 3 and recently tried to run some silk PLA. I ran into issues with the print stopping part way through the print. It acted like it had a clog. But I could pull the PLA back and then it would move through the orifice when moving the axis. I tried different temperatures and retract settings. Has anyone had issues running silk PLA? If so were there special settings that had to be used? I appreciate your help;.
