Blobs & Stringing
Everything was great until it wasn't. Using a 4 nozzle & petg at 230/85 deg. One photo shows a ton of stringing, another where the nozzle jumped one direction and then jumped in opposite direction ( side should be perfectly flat). The one picture shows the retraction settings. I think this is the problem but I have absolutely no idea what any of it means or how to make changes. It might not even be the problem. As for the 'jumping' I think that instead of the print 'crashing' and shutting down it just hung up on a blob and then jumped the gear belt (the belt tension is good) and kept printing. Any help would be appreciated.
Drying the filament will probably fix most of the stringing.
The other picture suggests you have belt or smooth rod problems. When you say "the belt tension is good", how are you measuring it?
Cheerio,
RE: Blobs & Stringing
Filament enclosure is 40%-45%. Belt tension test says it's good, plus it just feels right. However an axis test that allows says "XY axis is a bit skewed, good job" (but always said that from day one.
RE: Blobs & Stringing
40%-50% is quite a lot for PETG. You could get away with that when using PLA, but PETG should (in my experience) be stored and printed well below 30%.
RE: Blobs & Stringing
Ageed, that's far too wet, dry the filament.
Make your next print this:

It MUST be printed in Prusament PETG or the spring tension will be wrong.
Cheerio,
