Not sure if I'm doing something wrong but I've just upgraded to the latest software OpenBuildsCONTROL-Setup-1.0.248 but when I use the Z probe with my home made probe when I set the thickness to .5mm it keeps reverting back to 20mm.
Thanks for the bug report, will investigate Custom probe plate thickness setting reverts to 20mm on restart · Issue #132 · OpenBuilds/OpenBuilds-CONTROL
Just to duplicate the issue for testing, do you know when does it revert? - every time you open the wizard - every time application restarts - etc
