I have got hold of a Wabeco F1210 milling machine with Mach4 installed. I have used Mach3 on another millingmachine for years.
Problem 1: When I generate G-codes for thread milling using the thread milling wizzard in Mach3, it will not work in Mach4.
Problem 2: I am not able to change possible or relevant settingsin Mach4, which also leads to
Problem 3: I cannot make the edgefinder move by itself to touch and determine positions.
Can anybody help?

You need to explain why its not working, can you not load it or will it not run the code once loaded.
