    All you have to do is use a spacer block to get it to the right height. The shimming is for fine adjustment.

    Just from looking at your pictures I'd have to say that the reason they thinned the bottom of the tool changer is because the tee slot table is thicker than the plain table with bolt holes.

    It will come from the capacitors and overloading the transformer. Not an issue if you are not operating at peak accelerations on both motors constantly. It also helps to use a high quality power...

    You don't have to supply peak current. You have to supply 7.5 amps.
  5. Re: What is the catch with those JMC servo IHSV60-30-40-48

    I ordered a pair for a benchtop lathe project.

    I'll be hooking them up hopefully in January when all of the parts get here. Belt reduction parts, servos and power supply.

    They require 7.5 Amps...

    Re: Misaligned somehow

    The vacuum and dust collector can be put in a baffled box that allows airflow but limits sound transmission.

  9. Re: Spindle Turning off or not moving- Prolight 3000

    I've had two of the speed control boards fail. I've also had all the relays in the control box fail. Doesn't sound line your problem though.

    Re: Prolight 3000 questions

    It's this guy. He will make any length and I'm sure you or he can turn down the diameter.

    If I can't figure out a way to make one I'll probably get one from him.

    EDIT: Look at this, a collet...

  13. Re: New Machine Build - Massive CNC router for timber components

    Buy a used Biesse ROVER.

    Building machines is fun, but you've got contracts and time is money.

    The learning curve on using a CNC is something to contend with, and it's tiny compared to the...

  19. Re: Emco Compact 5 PC and F1 with Welturn/Welmill

    Hey man hang in there. Just keep reading and learning about your machine. It may take some time for it all to sink in and that is only as big a deal as you make it. Tinker and learn and don't give up!

    Re: New to cnc

    Have you made any progress?

    You need to be able to draw parts and then you need to turn drawings into G-code.

  29. Line Driver buffer

    Hi,

    So that chip is not an opto isolator. It is a line driver buffer which helps to maintain clean signals over longer cable runs.

    The actual optos are on the UBOB.

    Mr. Chips,

    Look at the opto on your board and look up the manufacturer's data sheet.

    The info you seek is there.
