@wwak84 Thanks for your reply!

Just had a small problem with my micro SD and build the RRF from scratch again. The issue is solved, sadly we will never know what cause it.

Very wired issue, yes i know.

On the first print of the day, my print home all axis and begin to print really high above the bed, offset with Z Babystepping makes no changes at all. Do not use auto bed level.

After stop this first one and send the same file again everything goes normal.

Any tips on how to solve this wired one?

I will post below the details that i think can be helpful:
