Here is the question and reply I just received from Ajax.
Captain Midnight,

Hi,
I am trying to install a Whitehorse probe. I am running Mach3 on the DC310B. The manual says to connect to H3 pin 6 and pin 5 on the MPU11. It says that should be input 481. My MPU11 I/O map doesn't have that input listed. It starts at 769 and goes to 786. To verify to connection by running CNC11, Pin 6 lights up LED 769. I tried setting  the Ajax Configuration Utility to Probe Input 769 and 481, but that will not light the Probe LED on the Mach3 diagnostic screen. My MPU11 I/O seemed to mapped differently than the manual's directions. I don't seem to have an Input 481 on my MPU11.
How can I resolve this?
Thank you
Captain Midnight

The Mach3 software has that input mapped differently than the CNC11 software. If you are trying to verify the operation in CNC11, when you press ALT+I, you will need to press F12 until you see inputs 769 thru 771. You could also use ModBus to look at input 481 in the Mach3 software to verify it is working. This is explained in the manual. Thanks.

I think you need to return to what Terry said earlier;

"From the MDI screen type G31 X-2 F10 (followed by return) . The machine should start moving in the X- direction then trip the probe with your finger to see if it stops".

If the machine does not move, then we need to establish why.
Does the X Axis DRO indicate the move ?

The setup seems fairly simple. Wire in the probe 2 wires, setup AJAX to tell it what port you used.  Then test the G31 to see IF it works.

I don't know why they write to dros 2000-2007 that is 8 axis's ??? they only have a 4 axis board and Mach can only do 6 total axis and can only probe/record 4 of them and I think the Dro1999 may be an LED1999 ????

Who knows ??   (;-) TP

After fooling with it some more, I have it working. G31 X-2 F10, will now give me movement. I am so happy. Thank you all for giving me a fresh look at this. Information provided with the Ajax controller is confusing. Now I want to get a probe center finding program working.

OK so if you trip the probe while moving does it stop and display the coords on the screen ?

The Center find program is easy look in the Mach Tool Box section under downloads at the bottom of the list you should find an example macro that is ready to go.

OOPS SORRY that may not work with the AJAX version.  You may have to reinvent the wheel with AJAX.

Hi,
The saga continues. I installed the Hoss modified screen set, that has a probing screen. With some adjustments, I have edge finding, corner finding, and inside circle center finding working. When I try to outside circle center find, it does some crazy stuff. Has anybody got that to work well?
