Any potentially useful information that is related to the problem
I just received a A1 printer 2 months ago. I purchased some Sunlu Petg for printing outdoor related items. I have tried to do research but there is a lot of setting in Bambu Studio and I cant seem to get it right.
Printing PLA is great but wont stand up to the outdoor elements so I am trying petg.
I am using the standard nozzle that came with the unit if that matters.
I tried using the Bambu Petg Basic, Generic Petg and Sunlu Petg filament profiles but always gets results like these for a clamp mounted mug holder.
Also I did buy a sunlu one spool dryer and use that for 6 hrs before trying to print, I did print a Ams lite enclosure and use desiccant beads to keep moisture to 10% humidity inside the enclosure with avg 70 degrees F. ambient temp in the room.
I am at a loss and if any more info or screen shots would help please let me know.
I have searched the internet but cant find anything that helps vs gets me more confused. Everyone has different parameters but just trying to get better than these pictures.
Bit late to the party but these are my settings with SUNLU PETG HF:
Nozzle: E3D High Flow ObXidian Hotend 0.4mm
Profile: Default SUNLU PETG Profile
Factor K: 0.024 (via Flow Dynamics Calibration)
Everything else is at default settings and I dry my filament before for 10-12 hours - I never have issues with these settings and I run my prints on Ludicrous mode too.
The last message from @Winni is very comprehensive though, so you’ve got some options here
It might work if it’s been written about extensively, because then it just reads it and summarizes it for you. Switching on expert mode will give you much better results than the free version will.
I’ve been using just the BL HF profile with no issues. I agree it looks wet. I don’t see pressure advance as the issue.
I use the same nozzle btw (on all but one of our printers we have E3D nozzles. I (and every printer can be different) haven’t had anything that looks similar to what you’ve shown.
I did research through basic chat GBT what settings should be changed and only change the ones they mentions. I’ll give it another test run and see what comes of it and let you know.
Factor K is the value that a Flow Dynamics Calibration generates (I think there’s an automatic calibration so you don’t need to work it our yourself too)
