One reel of PLA not sticking
I have been using Hatchbox PLA for printing and have not had any problems. I had a hard time finding anyone selling green PLA. I did not want transparent so I bought AMZ3D PLA in green. It would not stick to my bed at all. The first layer would peel right up or completely let loose and drag the print around. Changed back to Hatchbox PLA and everything worked fine with the print.
Is it possible to get one bad reel or manufacturer? Can the filament be salvaged? I have read that humidity can effect PLA. Would "wet" PLA not stick?

I'll just beat my head on my desk for a bit. What I thought was PLA was actually ABS. Yeah, that would explain everything. I'm surprised it was extruding at 215 degrees and definitely not surprised it wasn't sticking to a 60 degree bed.

Ooops...
Been there.
Done that...
a friend also printed the gear bearing in PLA, at ABS temperatures, and amazingly, it worked..
bit untidy, but otherwise ok. this was when I had the Mk1 setup
.... a while ago!

Re: One reel of PLA not sticking
Had a very similar problem a couple of hours ago. I forgot to change the filament on my printer from PETG to HIPS. Got a weird result. The PETG actually bound to the HIPS juice I had prepared the bed with and the print started OK until about half way through the first layer the print caught on the nozzle and pulled the print from the bed ripping the thin film of HIPS with it. I think if I had actually had the correct Z offset for PETG in there the print would have made it to completion although under cooled.
Still although I made a mistake I am very pleased with what I saw. It looks like it may be possible to use HIPS as a soluble support for PETG as the PETG had bound very well to the HIPS film. Perhaps that is something you can experiment with on your multi material setup Joan.
