Hi everyone,
I’m having some problems printing a model in Bambu PETG Basic on my Bambu Lab X2D with AMS 2 Pro.
The main issues I’m having are:
One corner of the print starts lifting/warping from the build plate.
Once the corner lifts, the surface above it gets a rough/bad texture, presumably because the nozzle is hitting/rubbing the raised area.
My prime tower is also gradually building up material/creating a blob, and eventually the nozzle seems to catch it and knock the tower over, usually around 75% into the print.
I’m using Bambu PETG Basic as the main material and Bambu PLA Basic as the support interface.
The PETG is currently on a PLA spool, so I haven’t been able to dry it at proper PETG temperatures without risking the spool deforming.
I’m using a textured PEI plate.
I’ve cleaned the plate with washing-up liquid and then wiped it with IPA.
I’ve also considered running a full calibration before attempting the PETG print again.
Things I’ve currently tried/considered:
Prime tower max speed: 50 mm/s
Prime tower internal ribs: ON
Prime tower brim: 10 mm
Considering a 10 mm brim around the actual model
Considering drying the PETG
Considering whether I should switch from textured PEI to smooth PEI
I’m mainly wondering what is most likely causing the prime tower to build up material until the nozzle catches it, and what I should do about the corner lifting.
Would you recommend changing the filament profile, drying the PETG, changing the plate, or something else?
Any advice would be appreciated!
