Hello

I bought a CNC control board from china and configured the Mach3 according to the manual of the board, everything works perfectly, but I'm having problems in the probe. I start the macro and the X axis begins, but when the probe does the grounding the X axis continues to work and force the cutter, what may be wrong ? Below this my setup and the image of the board I'm using.

 If anyone can help me,Thanks

first off all, go to diagnostic and have a look for the digiitze Signal,
does it come up if you hold your clamp to the cutter?

Hi, TPS

So, I haven't signal.

Thank You

Hi, My cnc machining is working, but the probe don't have signal, How could I solve it?

Thank you for help me.

do you have a link to the Manual of your Controller?

Hi, I think it will need some power supply, maybe the 24V, you should have it in the board manual ...

Hi

Yes, I have the USB Board Documentation and Board Schematic and my Macro.

Thank you for help me.

you have to have 24V power, just as I sent the picture, yours is the same, then checked the diagnostics card in Mach to see if the light comes on when touched ..

Hi Mach3CNC,

I have sent you a PM.
