Prusa MK3s+ homing during Printjob

I have a brand new Prusa MK3s+ which I assembled myself.

All the calibration tests turned out fine, and by now it prints.

What i noticed now during prints: every now and then the Printer homes it self during a Printjob. It doesnt seem to affect the print quality too much, but i have never noticed that on my other MK3s+.

I have done several resets and recalibrations. I have changed and relubed all the bearings.

Please help, kindly

That's the behaviour of crash detection. The first thing that comes to my mind is belt tension.
Check that the belts are not too tight and that they can move freely over the whole axis width.

thx for that.

Belt tension was checked and it is right in the middle of the suggested range.

I then relubed all bearings, but still had it.

What i did next was reducing the flowrate, by now i think my nozzle was hitting the seaming knots of my print object. So therefore i think it was due to over extrusion, but still not a hundred percent sure about it.
