@JoergS5 the construction of the lead screws are integrated into the stepper, so theres no adjustments that can be made.
i can how ever manually adjust where the screw lays on the endstop clamp but for reasons i have posted before i wouldnt put all that pressure onto the one little tiny screw.
-
And I cannot see exactly that this green connector is and how it is connected to the stepper, can you make a close picture of it please?
-
@JoergS5 the green your looking at it just tape, so i can visualize if each of the stepper is moving.
i use it to verify if the mesh is working or not.
-
-
So the trapezoid spindle is directly inside the stepper? Or is there a coupler between?
-
@JoergS5 these are integrated lead screws. there are no couplers.
-
Ok I understand now.
Now what do you mean by weak screw where you don't want the whole load on. Which "tiny little screw"?
-
@JoergS5 
-
Could you make a
M112M122 after a calibration test and look for error messages please? -
You can see where the top of the lead nut is embeded into the upper gantry. so technically i could cheat it and raise the gantry and tighten it down onto the lead nut with that screw.
-
@JoergS5 what do you mean after a calibration test?
-
I mean after you run your procedure for Z leveling which fails with 0.5 mm fault. After this test/macro/... make a
M112- sorry M122 -
here is the M122 pre leveling

I don't see errors (error counts or hiccups) in M122.
You should try the test of loosing one side and run the test again. Releasing the side is only for the test.
One idea is your little screw is connected to a plastic part. This part is much weaker than all the steel/brass around, so it will flex much more under pressure.
-
@JoergS5 what should i make loose? i mean why would i have all these issues?
i never had any problems with the ramps before. the auto bed level worked fine, everything worked fine, i just wanted a quieter printer and more features than that old ramps could provide me.
i would honestly say that theres nothing physically wrong with my set up but im down to try what ever.
-
@joehsmash My idea was that the Z movemement stuck because you have pressure between left and right side. This was the reason for my proposal. But if you know that this is not the reason, you don't need to make this test of course!
-
@JoergS5 also about that little screw, thats not an issue. its currently not holding any weight other than to just hold the clamp onto the lead nut so that my axis switch stays in place.
as i said before i could cheat it but it would just cause more issues.
-
No problem, don't do anything I propose if you don't want to.
