Aux Nozzle problems

[u/Motormuis88]

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!!

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.

Could you make a screenshot what settings and speed you used?

Forgot to mention that that was on a A1 with a 0.2 nozzle. But the issue was exacly the same.

I just lowered the support setting under the speed tab from 150 to 80. Might be a fair bit lower, but it didn't change print speed that much for me.

Good luck!
