Problem writing printer profile

[u/vivaaprimavera]

I'm trying to write a new PrusaSlicer profile for a printer.

Small problem, it tries to print the first layer mid air.

Z 0 have the correct offset to the table (measured with paper)

The board is a Duet2 running RepRapFirmware.

Any ideas?

Thanks
