I like to consider worst case scenario first, with when buying used stuff, and work back from there, i got the manual for the controller, managed to track down the manuals for both the spindle and the machine ( not orderd yet, just found ).

Am not sure the controller is capable of what i need, and it seems the only way to communicate with it ( is restricted to max 9600br,

The machine was allegedly working prior to removal so why would the screws be likely to be bent?
.

scrap dealers not machine dealers, might not of understood how carfull you have to loads these, and i wander why it ended up at there in the first place, instead of being sold in place.
