to add a little more information to this. I hae talked with him on the phone about this issue. Here is the break down.
With no limit switches connected to the machine (But they are set to active in ports and pins) When he opens mach3 he gets the LED lights on the screen for x and Y next to the DROS Z led is not lit.
When physically connecting the switches and prode to the drier box. The Z limit switch and probe do work. But X and Y do not. These switches have been proven to work on another system so that removes then from the problem.
We hae changed the LPT port in bios from SPP to EPP and this does not help.
The cnc control system is from Minitech, there was a problem with the cnc control unit a year or so ago, but it has been repaired. Limit switches have not been run on this machine in the past. We have verified that the switches are setup correctly in ports and pins.
Hope the background on the issue helps diagnose the problem a little better.
