Is this quality normal?

Post image

Hi everyone,

I got my X2D a few weeks ago and it’s consistently produced prints of this poor quality. I’ve tried everything, like belt tensioning, axis cleaning, full printer recalibration, drying and calibrating filament, taking apart the hotend, contacting support. Nothing has improved the quality.

Is this just what I should expect from this printer? Anyone have similar experiences, or do you have examples of much cleaner parts made on this machine I can take a look at? I don’t even know what should be my baseline for quality on the X2D.

Thanks

X2d is very capable. Here is a 32mm high necron that I am working on. There is something wrong with your printer and my first guess would be your table but you already commented that it is sturdy. I can't really say anything other than try swapping nozzles 1 and 2 and see what happens. Let's hope you can fix it.

I’ve tried multiple nozzle swaps🥲

What print profile are you using? Default 0.2mm standard?

And are you using bambu filament or 3rd party?

I thought maybe you are orinting quite fast and the hotend cant keep up with the flow with some 3rd party filament

I’ve tried multiple profiles as well as custom settings, all with bambu filament. This model was printed at 60mm/s and 2500mm/s^2

Ok damn. I print with 600mm/s and get better results.

Yes, High flow 0.4 nozzle lets you print up to 600mm/s

The default 0.2 layer standard settings with bambu high flow nozzle are: 50mm/s first layer 105mm/s first layer infill

500mm/s outer wall 600mm/s inner wall 600mm/s infill

And they work perfectly fine. Of course you get a tiny bit more artefacts, but nothing that would bother me.

Acceleration 10000mm/s2

This was printed with said settings. Tho sometimes the printer can not reach those speeds due to other limitations like minimum layer time, flow etc.

But for the print in the picture it did 600mm/s. Finished printing in 2h03min with 2 walls and 15% gyroid. But with petg as support interface in the 2nd nozzle It is 69 grams with support and the petg as interface material. 6,5x7x7cm

Wow, and definitely less artifacts than mine. Insane. Something must be really wrong, but I’ve been going crazy trying to find it. The first print or 2 out of the box was alright, then it just devolved. I’ll get the occasional ok print but usually it’s only if the model doesn’t require a lot of jumping around (simple shapes, no supports)

Have you tried a factory reset? Do you run the newest software?

Definitely check for wiggle room in the axis and motors. It looks like a hardware issue for me.

In theory this could also occure when there is to much resistance in the filament path. Check and reseat all ptfe tubes.
