I have a cnc router by andersonUSA. it was setup four years ago. There are hard stops on the x and Y where material is placed. these were replaced and now i have hundreds of programs that are off.

When I zero machine (g91 g28 xyz) and press the position button y and Z are 0.000 but x was some how set to 0.1255.

so that I do not have to change hundreds of programs I need to know how to change this proportional to my new material stops. There is nothing about this in my operators manual. Anderson will send a rep for 150 and hour. Can it really be that complicated.

the control is fanuc. The operator (me) is limited. I zero machine, m94 t15 and M97 t15 (or which ever tool is correct to start each day. load programs from pc and run them.
