Calibration MCalv

Hi everybody , I'm execute calibration TIG weld torch manually, I got a difference in calibration somewhere about 1...1,5 mm.
I would like to got a difference somewhere about 0,1-0,2 mm. In MotoCalv i execute tool calibration according to MotoCalv instruction,
but I did not receive the desired result. After MotoCalv calibration i received the following values: X - +115; Y - +60; Z- 310 ( i am attached manual calibration data and schema of my motocalv calibration)...
Please indicate my mistake
