Going to deep!

Hi, I´m having a problem with the depth on the Z axis. Its always cutting 0,7mm - 3,4mm to deep. My setup is DeWalt 611. I´ve done collaboration several times, boost up power on Z axis but it continous to cut that deep. It various from 0,7-3,4 mm. Might there be an easy solution that I am overlooking?

Did you correctly identify your z-axis rod when you ran easel the first time to configure the machine?

Are the set screws on the z-axis pulley loose or missing?
