Found this one in my Mach folder - I have no idea of it's origin.

I have been following with great interest and you really don't need any help because you are sorting it out just fine.

( hint:  if you reduce the acceleration in motor tuning or use 'exact stop' mode instead of 'constant velocity' in general configuration it may help )

Even a plain threaded rod with nuts won't have 1/2" backlash.................something is loose.

Rich,

You have to think outside the box.
An axis which is tight in one direction only can loose steps in that direction and then be 1/2" out when it returns, nothing needs to be loose.

Could it be that there is some tightness or binding in the threaded rods which is greater in one direction than the other ?

The Visual Basic version used is Cypress Enable and the commands and syntax in PDF format can be downloaded from here;

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 ?

Brian,

If you are measuring the voltage output from the computers parallel port then connect the multimeter between GND (0 Volts) and an Axis direction pin. The voltage should change between 5 volts (or 3.3 Volts) when the axis is jogged in one direction and 0 Volts when the axis is jogged in the other direction.
(the C10 can accept 3.3 Volt or 5 Volt inputs).

The problem you have at the moment is that the Digitize LED is defined on the Mach Screen as OemLED 825 and the Ajax instructions say that it writes the 'point of contact' to DRO1999. As it stands this will not illuminate any LED's on the Mach screen.
Somewhere there is an Ajax probing script (or routine for using a probe) which translates this DRO1999 into something that Mach recognises as the point of contact.
