GEC Gemini spindle drive from Boxford 260 VMC

[mike Goode]

Hello Nat, If you are referring to the direction change relays they are 240volt. I have a connection diagramme, showing the hard wiring, but no electronic info. You can get the diagramme from Yahoo groups/ Boxford users/files, or I can send you a copy if you let me have your email address.
Have taken an "educated" guess at the components to repair my board, and receive replacements today, so should know in the next couple of days if it fixes the problem.
I'm in Kidderminster.

Tank you Mike, I will try a look to see if I can find this document.
this afternoon I took apart the yaskawa contactor and realised how it operates and is connected, so hopefully the diagram will confirm this. I believe it uses the relays on the Oxford relay card in the rack to switch the inputs to live on the opposing feed. I have therefore wired the live inputs for both sides through the relays on the spindle controller board, therefore if I am correct, the spindle poles will change over depending on the relay operations through mach3.

i was hoping to get some nice pics of the board components today but I left my camera at home, and there were no spare cameras at work which was extremely surprising considering I work at aardman animations, where cameras are everywhere! Anyway, I will post some pics of the board tomorrow as will bring my camera in.
if you could email me he diagram if you have a spare moment, although I'm going to try and find the group, that would be appreciated.
