It would appear that your machine is using a proprietary motion controller, controlled by InfoCAM.
In order to use the machine with the current motion controller, you would need a Mach3 plugin (software) for that controller.
It's unlikely that one exists.
So, in order to use Mach3, you would need to replace the Infotec motion controller with one that works with Mach3, like the CNC-Robotica that you mentioned. There are many others. Not all motion controllers may work. It depends on your specific hardware and what type of interface is required. You may need to do extensive re-wiring.
