I've searched for a few days, couldn't find any info on it, "bottom" layers and "top" layers have a ripple going on, during long solid infill extrusions. I've tweaked settings, checked to make sure nothing is loose, cleaned and lubed rails, checked belt tension, z offset, filament, etc.
I'm completely stumped on this one, smaller surface area/shorter extrusions, it's not happening, atleast in a way that I've noticed.
50/50 shot that it'll cover itself up.
This particular part is only a prototype for fitment/hole alignment so quality isn't as important, but for the final part, it will be.
Any help is appreciated!
