    Re: Double fixed support on ballscrew

    Yes, this is VERY common to pre load the ballscrew. IT won't change your preload, as one end is fixed preload, and the other is floating with ballscrew tension. You will need to find your operating...

  5. Re: LB15 5000L-G Sudden Loss of Comms strange

    Your not unplugging the cable with the machine on are you? Thats a good way to wipe out the rs232 port on a 5000. The error simply means it times out waiting for data. You are using a null modem no...

    Re: Okuma RU1 board relays

    You must have an odd Cadet, all I saw had the RU1 board as well, and they are solder on.
    I can't seem to find my Cadet electrical prints right now, only the OLD LB15. I'll keep looking, they are...
  7. Re: Building CNC Control Panels to Comply with NEC and NFPA 79

    UL508A is also another good source for panel code, It goes through the SCCR requirements/calculations and when and where it's needed.

    Re: 6040 upgrade

    Doing the same with mine eventually. I think it would help, if nothing else the bearing blocks have adjustment on them to take up any lash between the rails and bearings.

    Re: PCMCIA

    From all my experience on those, the PCMCIA is connected to the MB with a small snap on ribbon cable, similar to a cell phone screen connector.
  10. Re: Fanuc 21 M - Memory card, DNC option not showing on controller

    You won't have a DNC mode, it was called tape mode back then. won't have "Device", "MEM", "DNC-CD" either. That was on newer controls.

    Re: lathe grinding ways

    We had a guy scrape a hardened bed on an old Mori SL65, he did a fantastic job actually, but took him a week to do 25 inches, and he was a master fitter. That machine still runs today, 15 years...

    Re: Chuck will not open

    Lb 15 probably won't have the Ru1 board, early machines used ICE cube relays.

    Re: Hurco SM1 Control Replacement

    The centroid would be a slam dunk easy button on that machine, especially if you went with the full kit with motors.( even interfacing the old motors and drive is simple on that system). Mach 3/4...

    Re: Source laser cutter help

    Can't see the image, but you'd probably need minimum 500watts in a fiber, probably minimum 1kw Co2, less if you went with stainless. Plasma if done right can hold pretty good size, i would think <...

    Re: Generic servo tuning advice, yaskawa

    Strange, according to the manual for that drive on page 308, it should have auto tuning..There is also some formulas to set the gains manually.
  16. Re: 2.2kw 24000rpm Huanyang Spindle won't exceed 12000rpm

    I think you need to narrow down whats causing it. Put the VFD in manual mode and see if you get the 12K or 24K manually. If it's still not right in manual, then you know its in the VFD.
  17. Re: How to successfully pause 3D printing and turn off

    Not if you want the part to stay on the build plate usually. Some printers have a power failure resume feature, but I find it only works if the power is out for a minute or two, once the bed cools...
  18. Re: Starting script needed for home made cnc machine

    Marlin is great for 3d printers, but not what you want on a CNC. Your way better off going with GRBL or Linux CNC or one of the other open source packages for CNC.

    Re: Source laser cutter help

    How large of pieces? Thats not a lot of budget for a full size sheet industrial machine, you'd need 15-20X that amount. In reality thats a good plasma table price range.

    The Regen circuit failed on one of your drives, yes i've seen the old school resistors/drives do this more than once.

    Re: mori nv5000 bleeding charge tank

    Yes. MDI mode-open bleeder, close bleeder, manual mode, tool unclamp/clamp a bunch of times, rinse and repeat. Now, if the Lucifer valve is failing/failed, all bets are off. Did you replace O-rings?...

    Re: Fanuc 21-tc with Fusion 360

    Sure hope you set the parameters up for the max RPM on that new chuck. Overspeed a chuck too much, and you have a bomb going off.
  25. Re: Haas VF-2 RS-232 Cable Using a Switch

    You would need pins 2 and 3 swapped. I would also caution heavily against using switches. Seen PLENTY of blown comm ports from those. USB to Serial adapters are like $10 now days, just set up...
