Just printed this plant pot and the quality is absolutely trash. It's a large print (150mmx150mmx150mm) but printed using my normal settings. It's solid wall - 4-5 perimeters thick. Sliced in Prusaslicer 2.6.1 and printed on an Ankermake M5. Any ideas?

Thanks!

Hmm. So, how...cyclic is the pattern? is the height between sections the same? I'm wondering if your lead screw isn't straight- as it turns, the lack of straightness causes the z axis to bend and flex back and forth a bit. small perturbations at low-z-heights would tend to grow kinda like that.

But I'm not entirely confident in this answer and we'll probably need more information like materials, temperature setting, layer thickness and part cooling settings, as well as sped settings.

I agree this is probably mechanical issue (Z leadscrew or wheels/rails). How other prints look like? Maybe print some other model and see if issue still persist, just to exclude gcode

What's the infill pattern?

I've seen bad wheels, misaligned wheels, or failing wheel bearings create these kinds of cyclic patterns as the angle of the wheel where the problem occurs introduces inaccuracy that adds up over time.

I don't know how helpful I can be from a diagnostics perspective because I'm not familiar with this specific printer, but I would suggest checking that your wheels are secure and true and ensure that your rails are unobstructed.

Are you sure it’s not the model?

[–] [email protected] 1 points 11 months ago

Yep - I made the model.

I'm going to dig through the slicer file and see if there's anything wonky with the number of perimeters.
