Discreet Physical/Hardware Jog Buttons - stumped

Discreet Physical/Hardware Jog Buttons - stumped was created by tripwire
I can't seem to get my hardware jog buttons to work. (I'm running LinuxCNC 2.8-pre.) I've connected separate buttons (switches) to the BOB for my MESA 7i67e. But I'm getting no response from LCNC when pressing the buttons.
Hal file code for a "jog X plus" button:
Hal Meter shows the expected response when I press a jog button:
Pin halui.axis.x.plus changes from FALSE to TRUE, as does the gpio pin.
But there is no indication that linuxcnc is receiving the command. (No error message if in the wrong mode or any axis movement.)
Any help is greatly appreciated!

Have you had a read through the halui manpage here ?
linuxcnc.org/docs/master/html/man/man1/halui.1.html
Seems to be some changes to the naming convention.
Tho it seems funny there is no "no pin error"
This is a brief:

Hope this may help you.

Thanks OzzyRob! I tried various permutations of the hal command. Will give it another try and report back...

When you tried to jog the machine using your above pins, had you homed the machine yet? Have you set a jog-speed? The pins halui.axis.jog-speed and halui.joint.jog-speed need to be connected to something for the jog pins to do anything.
Until after you home the machine you can not jog using the axis pins, you must use the joint jogging pins.
If your machine is a simple Cartesian gantry, simply connect both the joint and axis jog pins to your jog buttons. But don't forget to connect the jog pins for both gantry joints to the same button or you will rack your gantry.

Thanks Todd! Your suggestion solved it. My original syntax was correct. (Which, ozzy, explains the absence of a "no pin" error.) But I needed to set a jog speed. I have a GladeVCP panel in my gui with a jog speed slider. So I connected this to halui.axis.jog-speed (in a post-gui hal file, don't know if that's necessary) as follows:
#post-gui.hal
And in my main hal file I connected my hardware input to halui as follows:
In my case, there were drop-outs and spontaneous machine movement! until I buffered the signals with a debounce object. Final code for all three axis:
Thanks all! (Now it's on to some stepping logic...)
