Homing with AjaxCNC Board and Mach3

Does anyone have homing working using the Ajax board and Mach3. This is the one thing I can never seem to get worked out on my machine.

Did you ever resolve this? The M92 macro worked for me out of the box and homes off my limits. One think I have noticed is that this macro uses the Jog capabilities, so keyboard jogging has to be enabled in mach or it will not work.

6.1 Homing
Homing can be performed by typing “M92 P#” on Mach3's MDI line. This will cause the axis specified by the # sign (1 for X, 2 for Y, 3 for Z) to do a positive homing movement until it hits the limit switch, then it will back off until it reaches the index pulse of the encoder.
Multiple axes can be homed simultaneously by specifying Q and R values as well. For example, “M92 P1 Q2 R3” will cause the X, Y and Z axes to home in the positive direction. Homing can be performed in the negative direction by adding 10 to the numbers – for example “M92 P11 Q12 R13”. The M92.m1s file in the Macros directory is the script that handles this behavior.
