…

I’m putting together a custom printer, with triple Z for tilting adjustment. However, when I go to run the Z_TILT_ADJUST, it behaves very strangely. The first run, it does something relatively normal. Then on every single run after, it alternates between adjusting 2 of the 3 motors 2mm too high or too low, the last one adjusting fine.

Yes, all the motors are plugged in in the right order. I haven’t been able to find any information about this error. Could anybody help me? This is really putting a damper on my whole project. Thanks!

Hello @Quajeraz !

Have you taken care of this?

The first entry corresponds to stepper_z, the second to stepper_z1,
the third to stepper_z2, etc. This parameter must be provided.

https://www.klipper3d.org/Config_Reference.html#z_tilt

Also, when using virtual endstop, only Z has that endstop, not Z1, Z2 …

Hello @EddyMI3D,

Yes, I’ve set all 3 Z steppers up, and they all move in sync. I added the endstop to all 3 in the hopes that it would fix it, which it didn’t, but it also didn’t seem to hurt so I didn’t bother changing it back.

The citation refers to the correct assigning of the steppers to the points in [z_tilt]

5

The steppers are set up correctly, the right one adjusts every time. But it moves too far and always ends up overcorrecting and being offset the other direction

To anyone coming across this in the future, I changed from Octoklipper to Mainsail and now it works perfectly. Don’t know why, but it might help you as well.

You did not mention before you run with OctoPrint as frontend.
