I have a bug in the Z-offset calculation that I think I have fixed.
I need some testers that have a current working Z-probe-offset that they can doublechek taht the new version is calculating right.
The pay-back from me is the Marlin Configurator and a license-key (if you not already have it)
Send me a mail to c a b b a g e c r e e k ( a ) g m a i l . c o m with name and your current Z-probe-offset = M851
And I will send you a msi file with v0.24-beta
