    Re: Prolight 3000 questions

    The max you'd be able to use is really a 5" chuck. With a 6" chuck, you could spin it, but it wouldn't allow you to open the jaws much wider than the chuck OD, since that would hit the way covers.

    Re: Prolight 3000 questions

    Don't give up on the machine just yet - it's a very nice piece of kit. I have two, one complete with original control, and 1 with no control on it.

    Mine both came with no tailstock - very custom...

    Re: Lathe Questions

    You could also do a similar thing with a servo on the spindle, replacing the standard motor. Then you could run the spindle as a spindle, or position it for drilling. Might need a brake as well, for...
  4. Re: Need pinout for Prolight 3000 lathe turret cable

    I finally found the right circular connector (turns out you have to buy the insert and the back housing separately - Digikey US), and with some fiddling around, got it installed and the other end...
  5. Re: Need pinout for Prolight 3000 lathe turret cable

    Thank you, Intelitek!! I'll order the connectors and build a cable for testing. I'll post back here after I build and test the cable.

    Thanks for the link, Iron-Man. It's a few years old, but they may be able to help.

    The turret on this one is driven by a stepper motor, not a DC motor, so 4 of the wires should be no problem to...

  8. Re: Need pinout for Prolight 3000 lathe turret cable

    The cable I need is the one that controls the turret. It goes from the back of the machine housing to the control box. The lathe end has an 8-pin round connector, and the control box has a 9-pin...

  10. Need pinout for Prolight 3000 lathe turret cable

    I have recently purchased a turret for my Prolight 3000 lathe. It didn't originally come with one, so I don't have the cable to connect it to the control box. The turret is from a parted-out...

    Re: Source for small, cheap bt30 spindle?

    If you can find one, an old Emco Maier F1 CNC mill uses BT30 tooling for it's quick-change spindle. You could salvage one off that, but maybe not that cheap. These were good quality Austrian made...

    Re: Small Lathe Suggestions for CNC Retrofit

    If you can find one in the UK, get a Prolight 3000. If possible, make sure you get the original control box and computer (or at least the control card from inside it - proprietary and required). I...

    Re: Matt's Grizzly G0602 CNC Conversion

    According to Centroid, you do need to run 1:1 on the spindle vs. encoder. They suggest a minimum of 2000 lines/rev (8000 cpt with quadrature).

    I have several lathe projects in the future, and...

    Re: Recommendations for a USED CNC lathe.

    Yuo could look at Hardinge CHNC III or IV's. These meet nearly all your requirements, if you get them with 16C collets. They tend to have 7.5HP spindle motors, but may have had options for 5 HP. They...

  19. Re: Questions about building a CNC Router for Aluminum

    You'll find the blocks aren't all that cheap, so be prepared for the extra cost.

    Unless you go with a router, you are not going to find a spindle worth the bother for <$200. When you get into...

    Re: compact 5 cnc

    The spindle already has an index wheel, and an encoder wheel (100/rev, if it's like mine). You can re-use the spindle encoder stuff. It's optical, no need for prox. You can use a C3 board(from...
