petg is "weird" material for me ... I have a love/hate relationship with it and I have to say that bridging is still killing me ... everything else is great, if not for bridging problem I'd move from abs to petg for most applications..
printing 30mm/sec with 50% speed for bridge and 90% extrusion for e.g. I get nice string that looks perfect, across 5cm span, looks like it's going to be great, and then the moment it touches the second wall it snaps off from the nozzle and falls down
.. I'm trying to figure out how to make bridging work for a while with petg without any success
... anyhow the step1 is always to get that string, the single one, to span across and look good, everything else comes after (in v4 s3d fixed many things that make things great after this initial problem is solved)...
if you manage to get that to work ok (span one single string) please share!
adding some cooling during bridging might help, the printer I use for PETG is normally printing PC and Nylon and I don't have any part cooling fan there. maybe adding some part cooling, low pressure... maybe .. dunno .. following this thread carefully
integrates with Simplify3D and allow you to
Calculate print time accurately (acceleration, max speed, junction deviation all taken into consideration)
