Working config for xhc-whb04b-4 pendant

I had some trouble getting my "new generation" of wireless pendant to work in LinuxCNC.  Here's what I did to make it work:

1) I've had the "old" version pendant (an xhc-hb04) for years and it works great.  I did a new LinuxCNC build for a friends Bridgeport and though it would be good to upgrade to the "newer" pendant for that build.  The build went great but I could not get the pendant to work.

2) I initially tried to use the same config for the WHB that I used for the HB but it didn't work.  I found the LInuxCNC MAN page for the WHB model but that didn't work either.  Well, it did work but it took me time to figure out what to delete, etc.

3) At the end of the day, you need to do two simple things to make the WHB pendant work: 

3a) Modify you main .ini file with the following additions.  Note that the MDI commands for the Macros in the "HALUI" section are my custom additions.  I programmed Macros to zero x, y and z plus macros for 1/2 x and y.

[HAL]

HALFILE = xhc-whb04b-6.hal
HALUI = halui

[HALUI]
    MDI_COMMAND=(DEBUG,<1>)
    MDI_COMMAND=G10 L20 P0 X[#<_x>/2.0]
    MDI_COMMAND=G10 L20 P0 Y[#<_y>/2.0]
    MDI_COMMAND=(DEBUG,<4>)
    MDI_COMMAND=(DEBUG,<5>)
    MDI_COMMAND=G10 L20 P0 X0
    MDI_COMMAND=G10 L20 P0 Y0
    MDI_COMMAND=G10 L20 P0 Z0
    MDI_COMMAND=(DEBUG,<5>)
    MDI_COMMAND=(DEBUG,<9>)
    MDI_COMMAND=(DEBUG,<10>)
    MDI_COMMAND=(DEBUG,<2>)
    MDI_COMMAND=(DEBUG,<12>)
    MDI_COMMAND=(DEBUG,<13>)
    MDI_COMMAND=(DEBUG,<14>)

3b) Put the attached xhc-whb04b-6.hal file in the same directory as you other ini files.  Note that I have a xhc-whb04b-4 but the config and driver for the -6 work just fine

Just like everything linuxcnc (for me), it seemed impossible and took me countless tries to make it work.  In the end, when it's done and working I look back and it was amazing simple.

I'll link to a short youtube video to help others with this "hard but simple" procedure.

Hi Erik,

Was the -A version running on a 2.7 or less version of LCNC and the -B version on 2.8 or later?

Thanks for your question, yes. The early pendant was a couple of years ago prior to the 2.8 release. The new pendant was on 2.8

Eric,

Thank you for the effort you put into this. I am hoping you can point me in the right direction. I commented out the lines indicated by the 'diff' below in the xhc-whb04b-6.hal file you provided in order to get Axis up and running.
These buttons work:
Working:
RESET
* Stop
* Start/Pause
* Feed+
* Feed-
* Spindle+
* Spindle-
* S-ON/OFF

These do not:
* Select Axis knob
* Hand wheel

If i 'un-comment' the
whb.halui.axis.x.select line I get the following startup error:
./xhc-whb04-6.hal:45: Pin 'halui.axis.x.select' was already linked to signal 'axis-select-x'
