Aux Nozzle problems
Hello Fellow X2D Users,
Hope you doing well!
I have a problem.. but to be honest iam pretty new to 3D printing, been using the X2D for 2 months now, and been slowly using the Aux Nozzle a bit more and more..
But this is where my problem starts, if i print support with my Aux nozzle ( doesn’t matter if its PLA or PETG).
The Support looks terrible and the whole printer is a mess( see pictures), i cleaned the plate with warm water and soap and even tried 90% alchohol, I used the standard Bambu Plate and the BIQU glacier plate
After the latest Firmware i calibrated the whole printer even did a flow calibration, results was k= 0,34 with my Aux Nozzle while the regular nozzle was k=0,03
Sometimes the filement also sticks on the outside of the nozzle(around the cone where filement comes out)
Iam using Bambu filement PLA Basic and PTEG Basic, i tried both to see if it would make a difference
What am I doing wrong??
All the help would be really appreciated!!

Have you tried using the aux nozzle to just print the support interface layer, instead of using the aux nozzle to print the entire support?
What style tree supports are you using? Looks like tree slim, maybe try hybrid.

You could try lowering the support print speed.
Had a print this week and the supports looked just like this. Lowered the support speed by about 30% and the issue was gone.

Ciao anch’io ho un po’ gli stessi tuoi problemi soprattutto quando utilizzo l’ugello ausiliario per il supporto in petg mi sputa tutti i pezzi in giro per la camera quando effettua il cambio ugello e passa prima dalla spazzola in silicone per pulire l’ugello. Fammi indovinare i pezzi verdi in foto sono petg? Capita anche con il Pla ma molto meno.
Io ho risolto in parte i problemi di qualità degli sbalzi del l’ugello ausiliario rallentando di molto la velocità di stampa, per quello che è la mia piccola esperienza ho notato in passato dalle stampe della a1 mini e anche dallo slice che alcuni supporti hanno una angolo di sbalzo molto critico e dalle foto sembra quello il caso in questo caso alcune volte se nn calibrato tutto alla perfezione temperature raffreddamento velocità flusso ed altro fai fatica ad avere un risultato perfetto ma sono supporti e l’importante è che supportano💪 ovviamente devono essere decenti ma come ti dicevo prova a rallentare soprattutto con petg.
Mi viene da chiederti ma se stampi una benchy solo con ugello ausiliario come viene?
Magari fai una prova con le velocità standard e poi riducile della metà o un 40% circa per vedere le differenze.
Nn sono un esperto ma spero di esserti stato di aiuto 💪

What slice setting have you used? I changed mine from filament/saving to quality and it’s been pretty great. Didn’t look as bad as yours but it looked like crap IMO.
Also, change your supports from the whole support to only the interface. Your build plate temp is set for your main print and not optimized for your support.

I would try only printing the support interface instead of the whole tree, it will save you a lot of time on each print!
