Help with HB04 Pendant Issues

I had this pendant working fine but tonight it seems to have issues:

setting the step increment freezes, stuck at 100 - however the LED on the pendant blinks when step is pressed
The position does not update on the pendant.

All other functions work OK, I am able to jog, pause, stop, home etc...

It just seems those functions associated with the information on screen are a problem.

Almost like it can send information but cannot receive it?

I did a reboot and it worked initially then the same behavior occurred, so I am not convinced its a hardware issue.

Any help appreciated.

you can in first place make a button to yoour GUI and reload the line of the pendant inital
so it renews the internal settings
WHAt Version of Linuxcnc are you usiing

Thanks for your suggestion.

The pendant now seems to be working OK, I moved the USB to a rear port on the PC. However I need to monitor it going forwards.

I think your suggestion about initializing the pendant is a good one, the behavior I had was very similar to what happens if the pendant is on but the PC is off. It appears to send button presses but obviously doesn't receive any position updates.

It's possible this might reoccur so for now I can add a button to the GUI, but can you explain a little more about the code I need to to reload the pendant?

Thanks Andy

The problem has reoccurred, the pendant would fault very regularly today. It seems position values and step selection are the only affected functions.

During the fault I closed linuxcnc and tried to access the HC04 on the command line, It created all the pins, then found the pendant, then threw an error:
libusb_claim_interface: Device or Resource Busy
I restarted the PC and tried again and it worked fine.

I am really interested to know how to renew the initial settings as you mentioned, can I do this via command line?

I have looked for a line in my configs that might be a way to restart the pendant, all I see is HALFILE = LIB:xhc-hb04.tcl and APP = xhc-hb04-accels
APP = monitor-xhc-hb04 (not that I get any messages about connects / disconnects?

Any help greatly appreciated...

Hmm, I am again reminded of the reasons why I went with a non USB wireless pendant, particularly the google search which indicates how widespread problems are with this hardware. Same manufacturer but a bit more in the budget and they turn out something that is bulletproof!
