Hi Voltatek,
Thanks for the help, and I have tried using Mach3 with a parallel port connection.
All I get is as soon as I switch the machine on all three motors lock up and the program runs as can be seen on the Mach3 display but no movement on the X,Y or Z.
So I have tried a newer computer using a USB connector, this seems to have fixed my original fault.
Many thanks Len.
