Hello,

I recently introduced a fourth z axis to my printer (prior it had 3).  
After adding the fourth z to my printer.cfg and z\_tilt section the Z\_TILT\_ADJUST macro is acting up.  
The z position just is not being corrected. It keeps staying at around the same value (0.4) and stops after the retry counter/slight increase.

I already checked the wiring multiple times and the motors seem to be connected in the correct order according to the z\_positions in z\_tilt.

For z I use a Voron style endstop and an euclid probe.

The original Z\_TILT\_ADJUST macro is reconfigured to deploy and stow the euclid probe.

In the previous setup with 3 z axes the Z\_TILT\_ADJUST macro worked fine.  
Right now I am stuck.

My current setup:

I think you use the wrong method. You should use quad gantry level method. I got a voron and this is working perfect with klicky probe…

Thanks, one thing I should have mentioned is that I am using a moving bed, where apparently quad\_gantry\_level can lead to ‘undesirable results’.

The master config for z\_tilt suggests that 4 z steppers should be possible:

Ok, nevermind I just tried quad\_gantry\_level and it seems to be working fine on a moving bed 🙂 .

Thank you!
