Reuelt has made a good point - you need to enable the Charge Pump (Config / Ports & Pins / Outputs) if you have your G540 Charge Pump turned on.

ISSUE SOLVED

I have solved the Mach 3 issue having checked the pin voltages and determined the dual printer card I have used for several years was faulty as was one other and also a new express card was only 3.3 volts. 
 
I located an old XP computer with a on board parallel port and all works normally.

I thank all the contributors who helped to solve the issue.  Thank you.
