Set homing (data layer)

[AlbertoGiani]

i would like to set a new "logical position" to the axe without actually moving it, i have tried from nodered to use both the data layer function set-pos-abs with :msg.payload = {

    "type": "object",

    "value": {

        "buffered": true,

        "axsPos": 0

    }

} and homing with: 

msg.payload = {

    "type": "object",

    "value": {

        "buffered": true,

        "newRefPos": 0.0

    }

} but didn't manage to do it, i tried also to change the buffered value to false but it still didn't work, thanks you

Assuming you have a virtual axis (i.e. an axis to which you have not assigned an axis profile), you can use command ctrl-based-homing to affect an immediate position change.  For example, use the msg.payload below to set the axis position to 180 units.  Axis power required.

{
    "type": "object",
    "value": {
        "homingParam": {
            "newRefPos": 180,
            "travelDisLim": 0,
            "homingDir": "+",
            "refType": "STOPPED_POS",
            "dynForward": {
                "vel": 1,
                "acc": 1,
                "dec": 1,
                "jrkAcc": 0,
                "jrkDec": 0
            },
            "dynBackward": {
                "vel": 1,
                "acc": 1,
                "dec": 1,
                "jrkAcc": 0,
                "jrkDec": 0
            },
            "refMode": "SET_POS_DEVICE"
        }
    }
}
