I’ve been having some serious issues getting PETG to print well, and I was wondering what settings other are using with success? I’m using a bedslinger in an enclosure and normally i print PLA with 200mm/s.

What are you doing for nozzle/bed temp, cooling fan, printing speeds etc? enclosed/open?

What is your printer capabilities normally for e.g. PLA?

    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
