after a annoying bed leveling process with wrong instructions with machine.
mirrored touch screen Keys for z.
they more or less have not adjusted the ui from there other machines that have a gantry moving down.
so in the ui up key is moving bed down and down key moves bed up.
recomended step is turn knobbs down a bit before so bed springs are slightly compressed.
do a first z offset.
now manual adjustment on corners and called axulliary.
when you are happy press automatic to do mesh.
repeat process 2- 3 times and should be good.
If you do the z offset wrong it will smash bed in to nozzle.
