    Default Allen Bradley 8400 info

    Hello, I bought a Lagun mill with an Allen Bradley control. It all works well but I have no manuals with it. I have Fanuc programming experience but can't figure out how to set a coordinate system up on this thing. It uses "Fixture offsets" which I think is the work offset, I tried adding the G45 and offset number in my program but no luck. Does anyone have any experience with this control or have a working program they could send me, or any ideas? I would gladly buy a programming manula if I could find one too.

    Well thanks, my mill was from a plastics company but I doubt you are replying to help me.

    OK, I guess I am talking to myself in here, so, can anyone recommend a CNC programming book that would have Allen Bradley program specifics in it?

    Sorry wish I could help but have no clue on Allen Bradley controls, there is not alot of customers that use them in our area. Your best bet to find some manuals would be ebay.

    you may be able to buy a programming manual from Control Sales and Service in Lewisville Texas or Albright's CNC Support Services in Bozeman Montana. I've gotten Allen Bradley CNC stuff from both of them.

    Longer than I have the ability to remember I used to help build custom machine tools that used 8200 and 8400 Allen Bradley controls. Let look through my pile and see what I can find. I do know I have a bubble memory (for the control lol) if you need one of those. I'll see what I can find and shoot a post off asap ...

    I got the Fixtures part figured out finally, it has 12 fixture offset settings on one page. It has a "Last offset" setting for some reason, and that setting was set to zero, so it wouldn't use ANY of the fixture settings. Why you would want to block some offsets I don't know. I still can't get it to use G42 or pick up a tool offset so some info there might help now, maybe just a sample file with the initial settings on it.

    Hello...

    I have a 8400 mill that someone removed all of the opto relays.

    Does anyone have any interface information for the 8400 controller?

    Thanks,,,

    I am at a loss.
