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'

  Can you lsusb and see which hardware ID you have, I can't get my pendant to work at all.

Thank you so much for this tutorial, Erik.

There is one thing that is bugging me and I wonder if anyone can give me a hint on how to move on:

If I start the spindle in Gmocappy GUI, it starts to rotate with 6000 RPM as specified in the GUI settings but if I start it with s-on-off button on the pendant, it starts with 100 RPM. Is there a way to start the spindle with the pendant with the same speed as specified in the Gmocappy settings or at least with an arbitrary speed?

Thank you for help.

After lot's of thinking, asking questions, and some logic, I managed to solve this issue using two simple steps:

- to make the pendant button s-on-off start the spindle with the same speed as the GUI button before the S word is defined, add RS274NGC_STARTUP_CODE = Sx to the [RS274NGC] section of your INI file where x are the same RPMs as specified in GUI for Spindle Starting RPM (6000, for example).

- somehow, the pendant button s-on-off starts the spindle and also increases the RPMs for about 100 RPMs. In our example, the GUI would start the spindle to 6000 RPM while the pendant would start it to 6100 RPM. To avoid this, comment the following two lines in xhc-whb04b-6.hal:

# net pdnt.spindle.increase whb.halui.spindle.increase halui.spindle.0.increase
# net pdnt.spindle.decrease whb.halui.spindle.decrease halui.spindle.0.decrease

After these modifications, pendant s-on-off starts the pendant to the same speed as the GUI and the Spindle+/Spindle- buttons work the same way as in the GUI.

I hope someone will find this useful. :)

Erik (and the rest of contributors too!) - 
Thanks for all the hard work on this topic and sharing what you learned.  I'm REALLY looking forward to getting this running on my Tormach 1100 machine.  My understanding is that PathPilot is basically LinuxCNC with some customization so I'm pretty sure most of what you have found will be applicable.  However I'm stuck at square 0...  
I have followed the video and can see the wheel with the lsusb command, but the xhc-whb04b-6 command comes back with the command not found error and I can't seem to find where I can download/install the driver for the pendant.  I have been trying to find it on github, but can't seem to figure out how to get this.  I need to figure out where things are and then use the command interface in a terminal window as github doesn't seem to be playing nicely on chrome on my tormach and I really don't want to go yet one more layer deep into this multi day and numerous hour long journey... 
Any guidance at all is GREATLY appreciated.:)

Thanks!!!!
