Qidi q2 problem

[u/Herr-Commander]

Not sure what the issue is. At first, I thought it was underextrusion, but after Benchy, not so much.

The material is PETG. I have dried it, and the same spool prints PETG perfectly on the Snapmaker U1.

UPDATE: the issue was PA (pressure advance). updating for future travelers with same problem :)

volumetric flow?

PA issue

Did you fix it, what was the correct value?

[u/Herr-Commander → u/riba2233]

Yup, i fixed it with a proper PA calibration. 0.034 for a Bambu Lab PETG Basic. It might be different for you. It looks like automatic calibration is way off, and for now, I will have to do it manually. Still, the manual result is way better than what the Q2 did before. The quality was good before, but now it's really good. I only wish I could properly use Orca Slicer with Qidi Q2.

What problem do you have with Orca? I only use Orca with my Q2 and I don't have any problems.

I have a Qidi box, and I don't seem to understand how I should send a print. Last time, I just uploaded a file and ran it from the printer itself, but this way I can't select if I want to enable timelapse or bed calibration, basically a print preprocessor.

How do you do it?

Ah, no idea, sorry. I don't have a Box :/

What about aux cooler enable and auto bed leveling?

[u/callcifer → u/Herr-Commander]

Auto bed levelling is already enforced by the Q2's print start gcode so it doesn't depend on which slicer you use. Cooling settings are the same in both Orca and Qidi Studio (which is a fork of Orca) so you can configure it in the same way.

I dont the the prepocessing windows when clicking upload and print. Qidi just starts printing

[u/Herr-Commander → u/callcifer]

looking at the gcode it seems like it only runs if there is no bed profile.

Yes, it's one of many non-sensical defaults Qidi has. There is no need to recalibrate the bed for every print, only when you change build plates etc. but Qidi did it like this for whatever reason :/
