printing round tubes
Having trouble printing round stuff this is PETG and currently running 240c .15mm layer height. 2mm retraction yet still i get these.
400 mm with rapedo hotend.

stop retractions.

400mm/s speed?
Grimstod•348d ago
Ill give that a try.
For external perimeters i had it at 35mms and internal is 200

Any progress? Seems temps and speeds should be fine... What size nozzle? And have you tried taller layers? EM?

So right this minute i am trying out a different layer order. It was set to do outer and inner walls first then infill. I reversed that.
My layer height was 0.2 and i have also tried 0.15. Nozzle is a 0.4
I did a wider 0.55 inner layer width over the default .45 and that actually helped a little just not enough.

Petg is a tough one to dial in... Narrow window of settings that work - at least for me... What brand and is your nozzle brass?
Fwiw, I get good results printing with 0.3 layers with a 0.4 nozzle... I keep extrusion mult pretty low - near under extruding

That perimeter order change has worked Still a tinny few blobs but not many. Much i@proved.
Want results from more Discord servers?
