Yeah I'm having issues right now with material being super sticky and building up on the nozzle. after 30min of printing it has this blob of filament buildup on the nozzle which hits the print.
I do actually print from a dryer, but it has been stored in a non-sealing box for a while without silica, so maybe it's just too wet. I'm just not hearing the usual crackling of wet filament at all.
Getting the first layer height correct is another key with PETG. You generally don’t want to have your Z offset further down than it takes to get an even layer. Find that level, then adjust the extrusion multiplier on your filament in order to fill in any minor gaps. Lowering your Z offset to fill in those gaps is going to contribute to buildup on your nozzle. As far away from the build plate as possible has been the right level for me.
I can definitely print closer to the bed with other materials than I can with PETG.
Sometimes I get crackling sometimes not but it is still usually moisture. It takes a long time to drive out all the moisture from PETG IME
I'll give it 24h in the dryer before trying again then.
What fixed this for me was raising the z offset (as in making the nozzle further away from the bed)
