Not sure how you are making changes but if you are using your slicer I do not know how to tell you to alter that. If you are using the terminal and changing the stored M206 offset than you need to make the current offset .6mm larger.. Larger the offset of M206 Zxx.xx the closer the nozzle is to the build plate. To see M206 enter M503, to change offset enter M206 Zxx.xx then M500 to save reprint and verify. If you need more details I think I have instructions set to me when I first got the M2 from support.
