You will get that error if you have the HAL Configuration window open while Axis is exiting. The error is because HAL Configuration cannot find the pin because it was removed by Axis when it was exiting.

You could also achieve the same with the following in the .axisrc file in your home directory which allows you to update LinuxCNC without have to edit axis.py again.

Code:

def user_hal_pins():
    comp.newpin('notifications', hal.HAL_BIT, hal.HAL_OUT)
    comp.ready()

def user_live_update():
    if len(notifications.widgets):
        comp ["notifications"] = True
    else:
        comp ["notifications"] = False

You could have a USER_COMMAND_FILE instead of .axisrc.

See sections 12.3, 12.4, 12.5 & 12.6 here: linuxcnc.org/docs/devel/html/gui/axis.html#_axisrc

Hi Phill,
Thank you very much for the answer, modify the code because the .axisrc file does not work for me, it is in the directory where I have the configuration files .ini and .hal, formerly if it worked for me, something else I should do, anyway add your code via USER_COMMAND_FILE and it works very well, I admire your work here in the forum!
thanks
Chimeno

If you use .axisrc it needs to be in your home directory (I should have said ~/.axisrc). It is then used by every LinuxCNC config.

A USER_COMMAND_FILE allows you to define a different file for each config and it will take precedence over ~/.axisrc if you have both.

Hi Phill,
With your guide example I want to perform the PC shutdown by means of a hal-pin, how could a message appear on the screen "turning off PC" wait 5 seconds and turn off, for now this is what I have ...

Code:

def user_hal_pins():
    comp.newpin('turn-off-machine', hal.HAL_BIT, hal.HAL_IN)
    comp.newpin('turn-off-machine.is-on', hal.HAL_BIT, hal.HAL_OUT)
    comp.ready()

def user_live_update():	
  if bool(comp["turn-off-machine"]):
        comp ["turn-off-machine.is-on"] = False
    else:
        os.system('systemctl poweroff')

tried with these but it just didn't work for me ..

Code:

time.sleep(5)
os.system('notify-send -t 10 -u low "turning off..."')
tkMessageBox.showinfo("turning off...", "power off")

I get errors together, if you can help me with some guidance, thank you.
Greeting
Chimeno

Sorry, I meant to reply earlier but I got a bit sidetracked.

I think the following will do what you want:

Code:

sdShow = False
sdCount = 0
sdSecs = '543210'

def user_hal_pins():
    comp.newpin('turn-off-machine', hal.HAL_BIT, hal.HAL_IN)
    comp.ready()

def user_live_update():
    global sdShow, sdCount, sdStart, sdLabel, sdWindow
    if comp['turn-off-machine'] and s.interp_state == linuxcnc.INTERP_IDLE:
        if not sdShow:
            sdStart = time.time()
            sdWindow = Tkinter.Toplevel(relief='ridge', borderwidth=4)
            sdWindow.title('SHUTDOWN')
            sdLabel = Tkinter.Label(sdWindow, fg='red', font='sans 16 bold')
            sdLabel.pack()
            sdShow = True
        else:
            if sdCount > 5:
                sdWindow.destroy()
                os.system('systemctl poweroff')
            elif time.time() > sdStart + sdCount:
                msg = 'Turning machine off in {} seconds'.format(sdSecs[sdCount])
                sdLabel.config(text=msg)
                sdCount += 1
    elif sdShow:
        sdWindow.destroy()
        sdShow = False
        sdCount = 0
