I have tried to wrap my head around this for a while now but haven't been able to so I am asking here in hopes someone can help. I may explain this badly but if so ask as I really do need this info.

G28, then G92 Z xx.xx If I want my nozzle to be slightly higher when it goes to print than what the G28 says which way do I put it? G92 Z -0.05 or G92 Z 0.05?? One will make the nozzle go lower when the first line of printing hits and the other will make the nozzle not go as low. Basically with the G92 you are trying to fake out the math to think the nozzle is not where it really is in the Z direction so when it lowers to start the first layer it will either go lower (squishing it more) or higher (raised up) from the build plate.

Anyone know which way should it be? A whole lot of stuff in Marlin is backwards and I remember when I used a Z probe that was backwards too.
