High hotend position just on the first print
-
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:

@joaomedina In your homeall.g and homez.g
G1 H2 Z-10 F200 ; lower Z againI believe should be H1 not H2... H1 is for homing H2 is individual motor move
I don't know if that will fix your issue, if not, maybe try adding a start.g file (it will automatically runs at the start of your print) and have it home Z again.

@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.

@joaomedina Small problem with the micro sd indeed! Glad its working.
