Are these belt artifacts?
Struggling to get my VC4 hybrid to print at the quality of my VC3. One major issue Iām seeing are these artifacts. Is this from belt teeth? If so anything to help reduce them?

On the second photo the right most print is from my VC3 and the other two are VC4.
And why do I feel like this matches the "actual speed" shown in prusasclicer?
There is even a smoother section along the sides where the speed increases. see the yellow sections on left and right vs green on front and back
Are you printing from an STL file?
Yes I am, printing the same STL file on my VC3 though I have zero issues with this wave
They look like typical stl artefacts is all. Stl's have very low resolution, curved surfaces get split into faceted flat surfaces and can appear like this in your print.
May be unrelated, but it would be my first assumption.
The fact that they become less noticeable along the sides where the speed is higher on the prusaslicer display has me thinking it is mechanical but you may be right. I'll attach a video here in a second. I am sending the model right to prusaslicer from Fusion360
Interesting. I exported as 3MF and sliced and it looks better?
Seeing as you're doing that, try exporting it as a step file and slice that.
You may have found it! Top one is step and bottom is STL
A bit annoying as it adds and extra step to the process but If it prints better I will take it!
Yeh I only print from step files, the quality is just way better
I feel silly just discovering this now ha. I think my VC3 printed this PLA more matte so the issues may have been less visible. Thank you for the help! I will get a test print going shortly but i have a feeling this is the ticket.
hey if you export from F360 you need to change just one setting and the stl files will be nice as the step file's ...
just change refinement from medium to high

Can still effect things depending on the model geometry though. Stl's are 3D models constructed from lots of flat 2 dimensional triangles. Even high resolution stl files are still just dividing the curved surfaces into more flat faces.
Step files are true 3D geometry. If you have access to the step files for a model then it is always the more precise way - whether that actually matters to you or not will depend on the model as well as what you're trying to achieve.
Sure, but if you want to publish the model without raw file the you need to preconfigure the refinement one time to get the STL files like we know it š
Also, not sure what slicer you are using, but the resolution the slicer uses can have a large impact as well. In Superslicer, I have deselected
gcode_min_length and that improved a lot.
