So, I'm not sure what happened, but I loaded my PETG profile up in Cura this morning and started a print, WITHOUT glue stick on the bed... And it worked! Last week, the exact same profile was not sticking to anything: I could get one print out of five to stick somewhat with mondo amounts of glue stick, and even then there were bad spots. But today, the printer gods have smiled upon me. Every single line laid down perfectly on the bed with awesome adhesion. I was just exited and wanted to share, ha ha.
