Hello again!

I'm stuck on something that is probably simple!

Printer goes home when it starts a print, it will then raise 5mm, but when it lowers again, I need it to drop 6mm.

My printer's bed and Z stop are hard to line up, I will work on it again soon enough, but currently I have to pause the print before it starts, lower Z by 1mil and then its golden!

Is there any way to make it lower 1mil extra?
