    I have more then one pointers on my 3D view in openbuild controller… I reseted every setting, but it didn’t work. I even deleted openbuild and reinstalled it.

    When I start a new job, the program crashes. It gives different Alarm numbers every time I try. I use an Arduino Uno.

    Could someone help me?

    Sounds like EMI - make sure your Arduino is properly wired, shielded and all inputs filtered. Otherwise, consider a BlackBox


    Pressing Ctrl+F5 to refresh the UI should also work - the odd ones result from loss of comms caused by the EMI above

    Thank you for your reply Peter!

    I did everything to prevent electronical noise and EMI (see picture). I can move each axis on its own, but when I start a job (whitout plasma cutter turned on) it crashes. I did one job before this problem, but after this it didnt work anymore. Never changed the wirering.

    I consider buying a blackbox.

    Do you have any sugestions?

    Proper CNC suitable Inverter, or repurposed hand-cutting HF start Plasma?

    Get a CUT50L

    But why do I need those if the cutter worked before?
    When I start a job without the torch turned on, it crashes. So the plasma cutter isn't the problem right?

    I am using a CUT50C.

    Could be EMI from motors, other devices - is the Arduino even genuine (or $2 ebay special?)

    Yes it is. I get your point, but moving the z-axis individually, it works.
    So is this stil EMI from the motors?
