Compensation Map

Compensation Map

Hi everyone, this problem i'm having it's more service related, i have a manual CMM Mitutoyo with UD1 card and runing CMM Manager 2020, the thing here it's that in the X axis i'm having a deviation of 24 microns in a 400 mm gage, but i can't compensate this value no mather what i do to the compensation map, the squarnnes i can correct it, but the linears i jus can't, i'm not sure if this becasue of the manual CMM, in the past i've comppensated CMM like this one but with Deva controllers and i never had any issues with the compensation, any suggestions?
