GScreen limit switch issue

Ive added some limit switches to my machine which is currently using GScreen and everything is working as expected except for one issue. When im using my keyboard arrow keys to manually jog the machine and i trip any of the limit switches i get error messages that fill up my entire screen in a strange scrolling fashion . This does not happen when i run a program or use an mdi command and a limit switch gets tripped. I have no idea how to fix this....any help would be greatly appreciated.
Thanks

my guess here is the keyboard release event is not caught so it keeps trying to jog and can't so errors.
It's been a while since I've been in the gscreen code but I could look later.

This is 2.8? Do you use compiled version or an installed version?

Hi Chris, I was really hoping Id hear from you, thanks for the reply....Im using a downloaded version.

Hi Ivan.

I'm happy you are still happy with your Gscreen based screen.
First I'll point out that if you set up the system correctly that you should never hit the hard limit switches unless there is a serious mechanical/electrical problem.
You can use the limit switches as homing switches.
You probably know all this but I thought I'd mention it anyways - but that still wouldn't properly fix the problem you are talking of.

Next I wonder if you can post a pic of the multi error messages.
Finally can you run linuxcnc from the terminal and see if the terminal gives any clues.

Chris

here are some screen shots of the error messages im getting during a keyboard jog into a limit switch trigger. i did test the limit switch functionality with a mechanical switch physically wired to my 7I76 as a jog button and the error messages went away. i think that reinforces your assumption that the keyup event may not be detected.let me know if you have any ideas and thanks for taking the time to lend a hand.

Yes thanks for pics and your test.
I think if we cancel keyboard jogging on any caught error would cover this.
Now I just need to remember the code enough to make a patch to try

i did attempted to modify the key events in my gscreen.py but i dont know python programming all that well and i couldnt find out how to accomplish what you just suggested......i really did try though

Can you find and replace or edit this file in your system?

 

Hi Chris,
If I knew where it was, i can edit it or replace it......can you tell me where its located?

I would try looking in:
/usr/lib/python/dist-packages/lib/python/gscreen/

I don't use an installed version so can't confirm.
