The Sequel - Oh Blimey I bought a CNC Lathe (Beaver TC 20)
NormanV:
"Basically they are microprocessor driven computers with many custom algorithms for motion control, and I/O (input / output) to suit the application. So that horrid card that I'm calling 'Card-B' has on it battery backed RAM memory for machine parameters, an interface for the probe, and a bus highway driver to a remote set of I/O mainly hidden under the controller in the MPG and I/O crate"
Is that English? I have no idea what you are talking about.
I was brought up making cardboard boxes, they're a lot easier for me to understand than electronics, but I am still enjoying the story. :beer:

hehe, tech speak is a bit of a language all to itself...
I understand most of it, not sure what an MPG is (that was always Miles Per Gallon to me...), but I'm sure there's a perfectly rational alternative :scratch:

Manual Pulse Generator. A twiddle knob with an encoder on the back to allow manual driving of the axis when not under CNC control

Oh, that's ok then.
nrml:
With the boards appearing to use through hole components, wouldn't it be relatively straightforward (but tedious) job to replace the individual components that are damaged and salvage it if an identical replacement sub unit can't be found?
I presume the battery on the replacement board will be remotely mounted for safety and easier access.
