    Re: hobby cnc ez board trouble shooting help

    Cool. The offer to test and/or replace the regulators is still on the table. Just let me know. I want you to use the board and be happy with it. Now might be the right time if you're not using it....

    Re: hobby cnc ez board trouble shooting help

    Yes. U5 "feeds" the regulated 24 Volts to the input of U4 (the 5volt regulator). So if U5 was damaged, outputting less than, say 5.5V, then that would indeed cause U4 to read low.

    Let me know if...

    Re: hobby cnc ez board trouble shooting help

    First off, the fan connector is FOR A FAN ONLY. The regulators on this board are designed to run the board only.
    The MAXIMUM (and I'd be afraid to go there) you can pull from the +24V Fan connector...

    Dear rotccapt,

    Could be a couple of things.

    1) seems we can eliminate the power supply as you tried several (smart move)
    2) there are a couple of FAQs on my website that may give some...

    Re: Newbie Q's

    Yes, the HobbyCNC boards operate with just two pins (per axis), Step and Direction. These are TTL level signals.
    Yes, the stepper will lock when power is applied - if you've set the motor current...

    Re: X axis moving when not being used?

    How long is your parallel cable? I provide a 6 foot one with my combo kits, and 15 feet would be considered "long" for a parallel cable. The parallel standard is a single-ended, un-balanced circuit...

    Re: X axis moving when not being used?

    It would be unlikely for the other axis to induce movement in your x-axis.
    When you are running the tests, is the X-axis 'locked' (you can't move it by hand)? It should be locked.
    The inputs are...

    Re: DDMMV2 work with Linuxcnc?

    HobbyCNC works with Mach and LinuxCNC.
    Reliable and not cheap import junk.
  23. Re: 24v 5m led strip connected to 24v fan terminal?

    If you are talking about the 24v fan voltage on a HobbyCNC board, then NO WAY! 2 amps is a helluva lot. That output is only to drive a small fan at a few tenths of an amp.
