Only started 3d printing recently so I don’t really have any thing to compare against so I’m asking the community. How bad are these VFAs? Should I just leave as is or is this bad enough to try to troubleshoot?
I’m currently only doing functional prints so this is only a minor, cosmetic issue for now. However in the future that might change, so I wanted to check if this is mostly to be expected or if there is something very wrong.
3D printer is Core One running 6.4.0-RC firmware.
Filament is generic black PETG.

I would talk to Prusa, that’s why you pay $$ for their printers. They’ll know how to fix that.
True. I’ll try to do all of the belt tension troubleshooting on their website first and if it doesnt work I’ll reach out.
Looks like maybe ~2mm spacing on these lines so possibly just belt related.
Check if it’s worse in a specific axis, the belt might might just be too tight.Or offcenter, or something… looks like teeth from a belt, idler or pulley
So it is kind of bad I assume. Prusa recommends 96hz for the top belt and 92 hz for the bottom belt but i cant hit those numbers. For some reason my bottom belt is tighter than the top one. If I try to tighten the top belt more than the bottom one my gantry is no longer square. I think something is messed up so I’m going to just take the belt assembly apart and see if I can figure it out :/
Time to spend hours and hours tuning the VFAs out of your thousand+ dollar printer.
Here’s Noizie works multi month journey getting his fixed.

No need to do any of the physical mods. Prusa released software updates that also help so you might just need to skip to the end and do the belt tensioning.
I was under the impression that the vfas were caused by the belt teeth. I’ve also had those issues still after their last firmware update in July. Is there something that I’m missing?
Belt tensioning. They are caused by the teeth but ideal belt tensioning can lessen it.
I see no such artifacts on my Core One. I am only printing with Prusament PLA so far.
