Step Four precise 760 Mach3 setup

Hello i have an Step Four precise 760 cnc Router running xpertmill.

The company no longer exists so i need a new Software.

What do i need to run this machine with mach3 ?

i tryed everything ports and pins, is it the controller ?

i have the Xpertlink STEP-FOUR - Schneiden und Fr controller connected via USB and Ethernet.

is this controller useless with mach3 ? it costet me over 1k bucks.

i want to use 4 axis milling with one rotary.

thank you in advance :)

Unless it has a Mach3 plugin, it will not work with Mach3.

Ok thank you, so what do i need to buy to get it working for 3d milling?
