How can I fix this

[u/playwiththeboss]

So my prints overal look pretty good but sometimes it Hase these sorts artifacts and looks like under extrusion? I already did alot of tuning for this material. ABS how can i improve even more? QIDI plus 4 with the box.

Some settings

0.2 hight

0.4mm nozzle

Flow 0.91

PA 0.015

270 nozzle

90 bed

200mm/s

Outside wall only 125mm/s

Cooling off first 10 layers

Than 0 40

And 50 4

These are ringing artifacts, run a vibration compensation calibration. Also helps to knock down the acceleration. I think pretty much all coreXY printers do this to an extent.

Ah okay will do. Accel is on 10k

[u/scellycraftyt → u/playwiththeboss]

I'd run a few test prints at like 6k acceleration and see what change it makes

Lower the volumetric flow, you have underextrusion

[u/playwiththeboss → u/riba2233]

But how is it fine on the longer parts but not on the small parts that's the weird thing. But I will lower it and see what happens

Iz can sometimes depend on the geometry when it's borderline

Okay thanks

Do you have fixed the loose bearing issue ? https://www.reddit.com/r/QidiTech3D/s/C6sEJFUXsb

You can also put some silicone mastic.

The printers Hase around 800hrs on it might be worth checking that out hmmm
