I have a china built cnc with a Bit Sensor control board. I can't seem to find a way to wire a probe to probe x,y,z axis. The board looks like it will support probing. But I still can not find the correct way to wire the probe. If this board will not support probing than I need to know what board will work for my machine. I have a usb 3Axis 3040 CnC Router Engraver Engraving Drilling Mill Machine and using Mach 3 software.
I will try and upload some pictures of my control Box.
If someone out their has any information on how to wire this board and probe or what a compatible board that supports probing would be I would really appreciate it.

Thank You,
Dennis Killian
