    Re: Flow Control Not Working

    We are using a serial cable that injects bits between the tape reader and the control using an old PC so in a way yes. I suspect that the only connections are RX TX and GND which might be the source...

    Flow Control Not Working

    We have a very old Fanuc 3M control (1982) that has updated ROMs that should allow the machine to execute directly from data coming in through the serial port. However, the machine refuses to take in...
  3. Fanuc 3M-A D71 Firmware Upgrade RETROFIT

    We talked to the guy up in Canada from Nexas who sells the D71 ROM upgrade kit for the old Fanuc 3M control. The idea is that this new firmware is supposed to allow the machine to ignore its...

    Re: FANUC 3M DREP FEED

    Does anyone know what happened to the site or the guy who sold these upgrade kits? We are looking for one right now and it seems like they are unobtainium.

    Thanks,

  5. Anyone know something about www.fanuc3mdripfeed.com ?

    We want to enable drip feeding on our Fanuc 3M milling machine and I came across this dead website. Does anyone have the contact information of the guy who made/sold this product?

    Thanks,
    Justin

    I may not get a response since this is a dead thread. But I am curious as to what ever happened to these machines. We have an AM-1547 that we have been playing with. I have developed a soft spot for...

    Re: Slant JR Axis Stuck from Overtravel

    Fanuc 0T-C.
    I got the axis freed up. The hand wheel ended up saving me and I was able to move the axis. But the X axis still wont home itself on a RPR. Its just misses 0 and overtravels.

    Slant JR Axis Stuck from Overtravel

    Anyone who has worked with these older Nakamura lathes knows the odd trait that is the X axis direction. As you move closer to the spindle X is positive. I tried to change this by following the...

    Re: Cutting pockets from sheet aluminum

    Never mind! I got it figured out. Adding tool diameter to profile and selecting inside or outside does it. Onward!

    Re: Fanuc 3M Memory Expansion

    40m? Meaning megabytes? Or 40 meters of punched tape? I estimated this machine to only have 16K. We could do a lot more with 40MB or an extra 40m but our machine only accepts about 10K before we run...

    Fanuc 3M Memory Expansion

    So we have come to the conclusion that we cannot drip-feed to our Fanuc 3M control without a set of expensive chips from Nexus. I am writing here as a last attempt to try and save us some cash. Is...

    Fanuc 3M Drip Feed
