PETg First Layer Issues

Hello,

I have been having issues with my MK3s. I have printed an entire roll of Atomic Filament PETg with my Prusa thus far. Just recently I have been starting to have sticking issues. The print will not stick and will peel up. It then lifts from the bed and sticks to the nozzle. I have cleaned my nozzle and the bed with IPA and Acetone but to no avail. I thought it could be the gcode but I ran it on my friend's MK3s and it ran just fine, the same roll of filament. Any suggestions?

 

Thanks,

Zach

Smooth or textured PEI sheet?

Sorry, smooth sheet. I have yet to conquer my textured sheet. I've also tried both sides of my sheet.

Scrub your bed (whatever it is) with hot water and unscented dish detergent. I like Dawn. Rinse well. 

Dry with a clean paper towel. Never touch the print surface.

Now try your print. No IPA and definitely no acetone.
