Voron 2.4 Z Wobble Problem

[ReeZe]

Printer Model

Voron 2.4

Extruder Type

Clockwork 1

Cooling Type

Stealthburner

I have successfully set up my voron 2.4 250mm today everything configured so far everything works as it should.

My problem with the print is a kind of Z error that occurs regularly every 3.2mm on the picture you can see more.

If you measure at the larger point, the value here deviates from the target, does anyone have any idea what I can do here?

Mechanically everything can be ruled out, I have already checked several times and the error is too regular.

I have already removed the z axle several times, checked and reassembled everything as it should and it runs smoothly without any problems.
The stepper of the z-axis has been replaced and the belts tensioned/untensioned.

The printed part always looks the same, always at the same height, always the same structure.
Print should have 10mm and its 10mm.
It must be on the software side?

Error found. I use a heated bed from the Prusa MK3 and have only screwed it to the outside of the profiles, like the original from Voron. Heating and cooling causes the bed to expand so much in the middle that it forms a belly. Then it cools down again until the heating switches on, then it expands again. Another profile in the middle and the problem is solved.
