    Default Find Center Error "Probe Ignore, Activated at call for probe"

    Find Center Error "Probe Ignore, Activated at call for probe"

    I am getting consistent failure when trying to find the center using both BlueTex and HOSS Mmach3 screen and the center finding macro. I have swapped out cables and computers to try and rule out the problem but now I am beginning to suspect it maybe my mach3 configuration.

    I have tried both port 10 and 13 on the C10 board along with a 2.2K pull up resistor and every time I make contact between the port and ground the light in the probe area of the screen turns on as expected. Check out the video to see the strange behavior, any help would be appreciated. I have also posted the macro code below from the screens.

    On another machine where this has worked successfully I noticed quick jogging back to the start position after making contact but this has never happened.

    "Probe Ignore, Activated at call for probe" means your probe is already being triggered when the macro calls a probing move. It probably has nothing to do with the macro's. Usually it's due to noise, or possibly wiring issues.

    Problem solved by resetting mach3 configuration. I suppose I change a default setting at some point.

    Old thread same problem...
    Probe Ignore error message showed randomly on my Omio X8 recently and spent hours debugging ground wiring to discover a chip had landed on the X axis limit switch shorting the switch to the gantry. System returned to normal once I removed the debris from limit switch.
