I'm using a CNC4pc board. The guy who ordered it thought it was just an ESS but it looks like maybe it is a breakout board with an ESS installed?

Sorry I don't know more about the board, but the guy who did most of it quit, and the owner wanted me to finish it

Here is a link to the board's webpage:

Hi,
so where are you measuring the voltage, at the input of the breakout board OR the ESS?

Hi,
OK, phew!!! I am assuming the breakout board will reduce the probe voltage to a max of 5V.

When you operate the probe manually does the probe LED on the Mach4 screen light and un-light?

Hi,
Yes, the probe LED will light and un-light, and whenever the probe LED lights, Mach4 disables- then with the probe active and I can re-enable it and it stays enabled.

Thanks for all your help. I just found the L82 command and went out and tried that and it worked. Thanks again for all your help.

Hi,
I just discovered that L82 was simply going down and almost touching the probe. If it touches, Mach disables like it does for G31. So I guess I'm back in square 1.
