Bridgeport Boss 9 R2E4 convertion

Dont get rid of transformers and/or power supplies. IT has 24v and 5v power supplies you will need for the 7i77.
The large 460v 3p transformer I rewired and changed the taps so I could use single phase 220 input. I used VFD for the spindle 3 ph motor.
How far along are you with this? I am starting to do mine as my original control died on it.

I retained the drive transformer / logic power supply.
Both cabinets are gutted mostly.
I want to move back cabinet to the position of side cabinet (if I have enough room for components)so I can push mill back to wall.
www.grmolds.com/?p=57 is no longer available to me, can you access? I did print it off, so I do have his instructions.
I am getting ~130DCV from capacitor strip.
logic power supply is listed as 5 volt as well as + - 12 volt, do I power 7177 field power with 12v? I can get 24volts out of logic power supply by using both + and - 12 volt leads by using -12 as ground and +12 as hot, is that how I need to power 7i77?

Does this wiring diagram look correct?
I am not sure about the logic power supply, volts and 7i77 connection point.
Not sure about encoder connections, was following GR Molds direction best I could.

The picture is way to small, so i can not see clearly what goes where.

maybe this will help make image bigger..

Nope, that is still the same resolution, just cropped.
289x368 pixels is just not enough.
