I am trying to set up a touch probe for zeroing my Z. I have it working fine, and when I reference the Z it goes to the probe then stops. Without installing the TEX Blue screen can I just enter a code line into my post processor that tells Mach how thick my probe is? My probe is .85 inches tall , so I need Mach to zero that height above when it stops. I really don't want to mess with the Tex screen. Thanks.

SUre set your code up as a Macro that uses parameters such as  M1000 Q.85   The Q value is your offset height.

Then from your Post you just add the line

  M1000 Q0.85    when you need to reference the tool offset. Then Mach3 will RUN the macro and set your tool offset to 0.85.

Just a thought, (;-) TP
