Morning guys
I am going crazy because I am too dumb to install my sensing device.
I have built 426 into an old MH750 and now I have retrofitted a TT130.
Measuring tools works well but how do I have to adjust my TS640 in order that it measures the lengths of the tools correctly. Or do I have to change something in my tool file?

When I zero the tool plane and drive to zero with the arranged tool, then the positioning is incorrect.

I hope I explain my problem well enough for you to understand what I mean.
I have contacted Heidenhain per telephone a few times but they couldn’t really help me out.

Has anybody got a solution for me? Otherwise I will tow the sensing device into the next available river.
