Hi,

Got an issue with the default "Go to sensor" button ignoring tool offsets (X and Y axis).
It is possible to customize the script behind the button, or is it all hard coded?

Edit: Running LinuxCNC 2.9.2 with QT Dragon HD and Probe Basic.

Its in the python handler file
In 2.9.2:
     def btn_goto_sensor_clicked(self):
         x = float(self.w.lineEdit_sensor_x.text())
         y = float(self.w.lineEdit_sensor_y.text())
        if not STATUS.is_metric_mode():
            x = x / 25.4
            y = y / 25.4
         ACTION.CALL_MDI("G90")
         ACTION.CALL_MDI_WAIT("G53 G0 Z0")
         command = "G53 G0 X{:3.4f} Y{:3.4f}".format(x, y)
         ACTION.CALL_MDI_WAIT(command, 10)

in 2.9.3:
    def btn_goto_location_clicked(self):
        dest = self.w.sender().property('location')
        if dest == 'home':
            x = float(self.w.lbl_home_x.text())
            y = float(self.w.lbl_home_y.text())
        elif dest == 'sensor':
            x = float(self.w.lineEdit_sensor_x.text())
            y = float(self.w.lineEdit_sensor_y.text())
        else:
            return

        if STATUS.is_metric_mode():
            x = INFO.convert_machine_to_metric(x)
            y = INFO.convert_machine_to_metric(y)
        else:
            x = INFO.convert_machine_to_imperial(x)
            y = INFO.convert_machine_to_imperial(y)

        ACTION.CALL_MDI("G90")
        ACTION.CALL_MDI_WAIT("G53 G0 Z0")
        command = "G53 G0 X{:3.4f} Y{:3.4f}".format(x, y)
        ACTION.CALL_MDI_WAIT(command, self.calc_mdi_move_wait_time(x,y))

Thanks for the reply cmorley!

Can't see anything in the code that should make the scripts ignore tool offsets, so tried to dig a step deeper. Found that the tool offsets are ignored in G53 movements for machine coordinates, but not in G54, G55 user coordinate systems.

Is this a bug or a feature?

Is the solution to do the Go-to-sensor movement in one of the user coordinate systems for machines with multiple spindles?

You could use macro buttons to add your own button that calls arbitrary Gcode:
