Hello Guys!
I have a problem with my 3D printer.
Both models printed on standard Bambu settings, my own modified ones and different combinations.
The result is always the same: artifacts on the wall:
at the bottom P1S_GOOD (my first printer, as a reference) at the top P1S_BAD (2nd printer) .
This happens around the seam .
Filament: Eryone PETG-CF, 250 deg plate, 80deg bed.
I have some experience with 3D printing so I tried the following:
- Software
-
Pressure Advance - identical in both printers for this filament, changing to “0” makes no difference.
-
Changing flow - no difference
-
Changing retraction - no difference
-
Changing wipe - no difference
-
Changing speed/acc for all parameters (eg. outer wall, innerwall, infill) - no difference
- Hardware
-
Belt tensioning - no difference
-
Cleaning all rails - no difference
-
Lubricating linear rails - no difference
-
I swapped Extruder (from good printer to bad printer) - no difference
-
Changed nozzle (inc. changing thermal paste) - no difference
-
Checked and cleaned filament path - it’s buttery smooth - no difference
I’ve stuck to this particular filament because it’s the only one I use to print items for my e-shop.
Do you have any other ideas I could try?
I’ve been thinking about the extruder motor, but I can’t afford to stop one printer and test on another.
My conclusion is as follows: if GCODE is identical, PA identical, filament the same then it must be a hardware problem , do you agree?
Thanks a lot for any tips.
Regards!
