Probing bug with XHC-HB04 Pendant

[Magnum]

Hello,
I have a problem with the XHC-HB04 pendant plugin. When the MPG mode is selected, the probing doesn't work all times. UCCNC thinks the probe was activated when it wasn't and gives a error message.
To get the probing working I edited the probing makro M31 and switch to Continuous mode before probing and back to MPG mode at the end.
Now I want to use the autolever plugin, and I always have to manually switch to Continuous mode or it won't work.
When I forget to switch to Continuous Mode before starting the autolever code and get the error message, I have to shut down and restart UCCNC.
If it is not possible to find the problem with the XHC-HB04 pendant plugin, is there a way to run a makro before the G-Code is executed (after pressing Cycle Start or Run at the pendant)? I only found makro M30 which runs after the G-Code was executed.
Many Thanks,
Magnus

Thanks for the information about the issue.
We will check this issue out on our side soon.

Hello,

are there some news about this bug? I have the same problems. I`m using UCCNC 1.2031 with the 2017 screen.
Sometimes probing works and then there comes the error message "probe already activated". From then it comes everytime and i need to reboot uccnc.
I will try the fix from magnum.

@ magnum: have you tried the mpg multi and mpg single mode? Is it working? For me it does not work. Only "mpg continues"

Thanks alot,

Sven

Hello Sven,

Mpg Multi and Single Mode don't work for me either, but I don't know what they do and what I can use them for.
I wrote a macro to toggle the pendant on and off (faster then switching through the modes):

if(exec.GetLED(145))
{
exec.Callbutton(226);
}
else
{
exec.Callbutton(161);
}


And here the changes for the probing macro:
Insert this at the beginning:

bool MPG = false;
if(!exec.GetLED(145))
{
exec.Callbutton(161);
MPG = true;
}


And this at the end:

if(MPG)
{
exec.Callbutton(226);
}

Hello Magnum,

thanks alot for your answer. I will try your fixes in the evening.

Kind regards,

This works.

I'm using it with my SegMag, I wrote a function that can be called at the macro start and end here's the code
