Thanks Brett, so far so good.

Well made a start on the control electronics and cut the circuit board this morning. I am hooked on this 'isolation routing' method for making simple, one off, circuit boards - it is so simple and with no mess. Now to fit the components and bench test it.

Pins 18 to 25 inc. are all ground.

Yes - that is the way to test the input pin functions - thanks Hood.

Sorry Hood the answer should have been No you can't Sir. (my first mistake of the day).

Using Parmon:-

With nothing connected to your PC parallel port, if you can toggle the state (by clicking on them) of the pins you suspect (the ones the limit switches were connected to) then your parallel port is OK and can be ruled out as being the cause of the problem.

Update:- JigSaw please disregard this as it will not help identify bad input pins on the LPT. It is only for output pins (my mistake).

Sounds to me like you may have blown the pins on your computer port with perhaps too high a voltage getting in there.
Test the parallel port input/output operation using Parmon which can be downloaded from here:-

That will at least rule out one possibility.

To get the best results from Mach, it is like Rich has said, you should use a dedicated PC running Mach and nothing else. This way no problems will be experienced.

There are quite a few explanations for use of the touch plate here on the forum but, if you wish, you can see how I set up my tool positioning here:-

Hope this helps.
