Denford Software & Machines

I have recently acquired a 1985 Easiturn 3 lathe.
The machine has been stored for several years in a warm dry workshop and appears to have done very little work.
When switched on the x axis moves out and references but I then get a message 'Motor drive fault in z'.
Could anyone point me in the right direction as to what the cause/solution to this problem may be. ??

Take a look at the LED's on the CD20 drives. The cover on the PNC3 control unit will slide forward once you remove the screws on the side & top.

I've taken the CD20 manual and made the text searchable and added to our site (in case the Parker one ever changes)

One cd drive (z axis) is a CD20 Circa 1984 no leds are alight on this unit
the other drive ( x axis) is a CD60 Circa 1992, this is showing a green led
I am going to swap these units round and see what happens.
Are these units still available?

I'm pretty sure we don't have any left here but Parker may still have, if not then ebay...
