Typo? What nozzle size did you print the parts with? Am using 0.32mm layer height with 0.6mm nozzle.
Not needed if your printed Z nut and stub are sliding smoothly… But I vaguely recall someone (SupraGuy?) suggesting printing Z nut and stub with different layer heights so their layer lines physically can’t mesh and lock together.
That said, I don’t have other suggestions on root cause, but I appreciate this context you shared…
Personally… I’d ensure thermal stickers are on all the Stepper motors and increase the ampage for now, and get on with using the machine… use modest feedrate and cheap materials. Try to get some joy/utility out of the machine asap. I’d keep thinking about this and balance tweaking vs other things noticed when cutting different jobs.
Are your rails parallel? If you remove the lead screw nut, does the rail slide smoothly or does it bind? When installing the rails, the trick is to put them on loosely and attach the plate loose as well Then move the plate and rail trolleys along the rail to get them to line up and then the tighten the rails to ensure they are parallel. If you loosen your rails does it still bind?
Yes sir I did do that. Even before I loosened the linear rails it moved very well. But when I increase power and set both z-motor amps from 0.8A to 1.0A, it runs flawlessly. So I am going to just get on with life as Aza suggested and machine some dang wood.
