Here my detail of Mach3 Config

1st, Config Port for using Probe

2nd, Edit button script

When click Opertor–>Edit button script , all of color box (yellow , red box) will flashing then press “Auto tool zero”. The script dialog will popup and you need to put you script here. for script see link above.

Note :: It’s was easy and make it work by specify you plate thickness at this line of code.
“PlateThickness = GetUserDRO(1151)” change to “PlateThickness = 1.5”
and “1.5” is depend on unit that you using in Mach3 if you set to Inch that mean your plate thickness is 1.5″ but if you set to mm that mean your plate thickness is 1.5mm

This is my wiring and detail
