Hello, here is what I'm breaking my teeth on ............... and almost broke my machine!
starting from the same point the commands G1 f800 z30 and G0 z30 do not result in the same final position, the ini file being unchanged, of course. As if the G0 command did not apply the same "scale" or reposition the OM.
I specify that the display at the end of the execution of the G0 Z30 clearly indicates 30, while the actual displacement was something like 5mm.
Cordially.

Bonjour, voici sur quoi je me casse les dents ............... et ai failli casser ma machine!
en partant du même point les commandes G1 f800 z30 et G0 z30 n'aboutissent pas a la même position le fichier ini étant inchangé ,bien sur. comme si la commande G0 n'appliquait pas le même "scale" ou repositionnait l'OM.
Je précise que l'affichage a la fin de l'exécution du G0 Z30 indique bien 30 alors que le déplacement réel a été de l'ordre de 5.
Cordialement.

Could it be that you are losing steps as the G0 command would be at rapid speed but the G1 would be moved at a much slower speed

Lower the velocity of the Z axis, by half as it looks.
In the ini file, Z axis and joint n section, where n is the joint number for the Z axis usually 2 or 3, max_velocity should be set to roughly half of what you have now.
