@arhi said in I thought it was z wobble...:
I can't see from the images, is the issue parallel to the XY plane or is it under angle)
they look pretty much parallel.

So the line width is varying but only to one side...
Is the hot-end perpendicular to the bed?
yes but the width variation is not always on the same side. if the head wasn't leveled shouldn't the wavy lines be always on the same side?
but I'll double check that. Thanks!
How tightly screwed down is the drive gear adjustment screw on the extruder?
I tried to make it very loose and very tight but I can't say I noticed much difference.
Are the drive gears clean?
How consistent is the diameter of the filament you're using?
I'll double check that but it is supposed to be good quality.
Are you using any pressure advance or nonlinear extrusion?
No, I disabled everything while testing.
PS: just wanted to thank you @mrehorstdmd for your great blog, I've built my printer mostly thank to your posts
