PETG troubles..
Hello.
I recently put on a fresh spool of PETG.. no matter what settings I play with, slowed everything down to a snails pace, I can't get a good print.. the first layer comes out perfect.. any subsequent layer prints like garbage.. i thought it might have been my orbiter v2 run_current setting being low as it appears to be an extrusion feed issue.. with assistance I was able to resolve this but still, no go.. any help would be greatly recommended. Photos show the first layer, then the other side showing the crap print that follows..
Nozzle temp is 240 - 245..

Petg does not like rapid movements. So retraction speed is important as well as distance, next overall acceleration, try to get really low as well to see if it helps. Cooling is needed but not too much like with pla. Also all the stuff from retraction settings can be useful like wipe while retraction and ramping movements
And there is infill anchor setting that makes infill layer as one big line and reduces retractions a lot
