I have done a clean install of XP pro up to SP3 reinstalled Mach3 and set it up to use the native LPT1

Perhaps try LinuxCNC? Even if you don't want to use it in the long term, if it works you'll know it's a software problem.

The only up-side of the issue is that I am saving money by not breaking cutters. Is there a market for 3.17mm diameter TC rods about 25mm long ?

I occasionally use the bench grinder to turn them into V-cutters, which are fine for simple PCBs. I've got enough for now though!

I am not against Linux, but I didn't know there was a CNC flavoured one. I have got Ubuntu, so I will load that and try it. However, I am going to try one more time to use Uncle Bill's operating system on another computer.

pop over one night with a packet of hob nobs and we'll bang them on the T&C grinder and make them into proper engraving cutters.

Two packets surely as they're half price at Sainsbury's!

Just to be clear you have to use the version specified on the LinuxCNC site, else it almost certainly wont work.
