Lathe project

I been wanting a small Cnc lathe for awhile now.
One of my requirements was to have its own stand / enclosure.
I was mainly interested in just the iron.
My initial plan was to strip and rebuild it mechanically and electrical.
I looked at different controller mach3 (old) Mach 4 ( buggy I heard) acorn (expensive) masso ( only does x and y)
Found grizzly 924 on fb marketplace for cheap and the guy even delivered it.
The closer I looked at the fuzzy pictures I realized it already had a mesa card it it with two expansion cards.
So this is my intro to Linuxcnc. 
first steps
1: clean it 
2: put it on wheels 
3: power only the motherboard and replace battery.
4: bring up the 220 mains.
5: see it the old controller still starts up.







 

Nice little machine.
Keep us updated.

So the machine has
5i20
7i47
7i37 TA

New plan 
Discard existing control motherboard dead.
Purchased new mesa 7l96s. Already have a Rasberry pi 4.
Remove all lathe components to clean Hardened and crusty chips.

That is a very good plan!

Removed all the old crusty wires.
While I probably could have repaired it is easier just to redo it with updated tech.
All the relays and contractors were 220v coils. Wire insulation was hard and crusty.
