[BUG] (z-offset for bl touch is inverted, and value increases with each print) #747

Description

basically I switched from a skr e3 dip v1.1 to a skr e3 mini v2.0 because my old one broke, and I've managed to get everything working, except from one thing which is my z offset is inverted, basically when I lower my z axis it lowers the nozzle but if I lower my z offset, it lifts up the nozzle, so while printing lets say I have a initial z offset from the wizard of -1.1, but I need to lower it a bit during printing, I have to increase the z offset to lets say -0.9, then next print the gap from the nozzle to the bed doubles so then the offset is now -0.5, then its 0.3, and then 2.1, and it just keeps on going, I've made sure that the wiring is correct because it seems like the wiring is different on the mini v2.0 compared to the dip v1.1, I've also posted this on reddit but people couldn't find out what the issue was.

Expected behavior when you decrease the z offset, the nozzle should lower

Actual behavior when you decrease the z offset, the nozzle lifts up from the bed
