Small Chinese K40 laser conversion (DSP upgrade)

Hello everyone,
I just purchased a K40 laser and intend to do the conversion to the lightobject DSP PH-BOARD V2.0.
The machine must have had a collision. It was damaged when I opened the double boxed shipping and the intake cooling water glass connection was broken off the left side of the tube. I notified the shipper and they will provide a replacement tube. Everything in the literature package was scattered throughout the machine and the shipping box, water pump was just tossed in too, it's box was flattened. I didn't know where to begin until I found the CD that was mixed in with the packing material. I strained all the material and found the memstick.
There was no data on the USB memory stick. Is that important and if so can I get a copy of the memory stick files from anyone if necessary?
I have some CNC integration experience, very sparse on laser, and am looking for information or suggestions, that might help me out so I don't have to re - invent the wheel.
I'm looking for drawings showing assembly of this machine.
Following is a list of some of the detatils I have to deal with.
The work piece holder has a spring clamp, and the aluminum plate it's mounted in is bent down out of shape. I think it has to be flat so that it's surface is normal to the beam, is that correct?
The aluminum plate seems to be mounted on hex stand offs to the cabinet bottom. Is it a good idea to remove the plate and straighten it out or should I just replace it with another work surface?
I saw one guy's machine design that used perforated metal for the work support, similar to what's one power supply elclosure. Is perforated metal a better material choice if I replace the plate?
The home limit switch is in the top left hand position, can it be located in the bottom left position, where most of the drawing origins are?
Are there any drawings available for the mechanical assembly of the components, which might explain how to take out the assembly containing all the linear rail, and motor drives, belts and pulleys? The gantry is binding slightly in 4 locations, I guess it's a bent shaft, causing the problem.
I want to connect the X axis motor that provides the left and right carriage movement. The X axis motor and optical limit switch appears to connect to CN3 on the K40 board with a flat white 12 conductor ribbon cable, similar to Parlex Micro cable, as seen on plotters and printers. How do you make connections to the ribbon cable conductors for the 4 motor conductors to the stepper motor, and also access the 3 or 4 limit swith conductors? The ribbon cable is inserted into a thin, edge connected socket on the K40 board.
Have a happy fourth.
cheers,
Denis
