    Re: Input Stopped Working

    Directly connected. Is there a stand alone opto isolation device that I can add? Although the driver box is about 13 years old so I don't feel too bad, I don't feel I'm a lucky person either.

    Re: Input Stopped Working

    Fixed! Or rather a suitable work around. Moved the probe to an input on port 2 of the ESS. Thank you Warp 9 for providing 3 ports!

    Finally back to my SOP. Sometimes you don't realize how important...

    Re: Input Stopped Working

    The input pins are pulled up. At least the ESS is much easier to access. I see if I can do we checking there.

    Re: Input Stopped Working

    Pretty sure that's it. Been a while since I layed eyes on it. Like, three days, so of course I can remember.

    I'm also using an ESS so the problem could be there also?

    Re: New Machine - New Problems: e stop issue

    Thanks for everyones input and assistance. It's wierd that it will cut air without issue, but as soon as the tool touches the workpiece it triggers an e stop.

    Re: New Machine - New Problems: e stop issue

    I ran a small part by zeroing the tool and then removing the probe connection from the spindle mount. E stop within a minute. Not to say this isn't how the noise is being introduced, but there was no...

    Re: New Machine - New Problems: e stop issue

    The machine frame is grounded to mains ground. The spindle mount is aluminum and has continuity through the frame, but that does go through the linear motion bearings.

    I'm also using the spindle...

    Re: New Machine - New Problems: e stop issue

    No. The VFD cable is not shielded. I may order some shielded cable and replace it. I find it odd that I'm getting false e stops and the FVD cable is a long ways from the e stop wiring.

    New Machine - New Problems: e stop issue

    New machine. FLA 100. New Chinese spindle(Hyunyang 2.2kw). I'm getting an e stop almost as soon as the tool starts cutting. I've heard these cheap spindles and VFD's are noise factories too.

    I did find that the Y axis rails were a bit wobbly so I added this box structure to the rear which stiffened it up dramatically. It will also make a great place to lay my cable carrier!
