HI Guys,
Just starting out with PETG from MG chemicals (White) and having some issues. I am wondering if moisture in filament is a huge problem.
My sad story goes like this.
Working with a large sized 2mm thick walled item.
Prints in PLA good, but environmental concerns (Higher temperature application) forced me to try something else. Can't have the smell of ABS. So tried PETG. First item printed fine( lots of stringing) was printing at 228C. Vendors says 210-240C.
Then could not get a print to go past raft and first couple of layers. Blobs and bumps.
Finally gave up and tried to print with PLA.
Nozzle was plugged but finally got it cleaned out and is happily printing PLA.

So what changed between print?. Its an 18 hour print so the one thing was filament went from sealed package to room humidity.
Its the wet season in BC so our humidity is high, 50-90 % the last few days.

Suggestions welcome.
Dave
