    It must have been noise from servos or VFD and improper grounding. That was mu conclusion, though i have grounded everything perfectly fine in my opinion. And still had problems.


    yes, 100% you have to EMI protect the Board to Drive wires. maybe that will solve the issue. Try passing a separate wire from PC body to board ground or box ground/ not VDC-/. Same to VFD if you have connected / PC to VFD/. Watch VFD revolutions with spindle turned ON and you will see if that makes effect, speed will rise.

    My advice is to buy the 4 axcis DDCSV controller in the future and use that in Cheap machines. Send the Pokeys back to them for refund if you can not solve it.

    Thank you Boyan for your fast reply and for your usefull informations. I will try to EMI protect the wires and i will inform you about the results asap.
    Probably i will start doing this on Sunday. So we will communicate again very soon.

  4. Just to add my 2 cents, my pokeys57cnc has been working great so far on my machine with mach4. Probing seems to work well with my 3D touch probe too.

    I do have everything run via a star point ground, including the spindle and all shield wires... so perhaps noise is indeed the issue.
