Job stops while checking file / running file

[kebucha]

Hi,

I’m testing gSender for use with a new GRBL based cnc in our makerspace. I really like it and would like to use it, but I am experiencing the job stopping while running the file below. It’s happening at different line numbers but always around 90 % done. And it’s also happening when the file check is run upon loading the file. So I don’t think it’s the usb cable like in some of the other threads I found around here. There seems to be no error or error message.

The cnc came with some home brew controller software and running the same file using that had no issues.

In addition I tried with UGS and it also completed the job every time.

I tested with gSender-1.5.7-Linux-Intel-64Bit.AppImage
and gSender-1.6.0-Edge-3-Linux-Intel-64Bit.AppImage.

Any ideas ?

Thanks for making the software available btw, really appreciated!

I can’t attach or link a file since I am a new user it seems, so I had to paste it here:

I’m not seeing the same results on Edge-3 or 1.5.7 - both are completing as expected on grbl both running and with the check file on load option.

Check load:

Running normally:

From here, we’ve got a couple things to check out:

1. I’ve bumped up your trust permissions so you should be able to post/link to the original file. I’m wondering if it has something to do with line endings that’s not reflected when copy/pasted the shared code.
2. Homebrew gbrl makes me a bit nervous - could you just verify it’s a standard grbl version by sending $I in the console (it should be 1.1h.xxxx reported back as ver)
3. It could still be intermittent USB issues - like an OK being garbled back on transmission would mess with the character counter algorithm for sending resulting in an early halt. A quick scroll through the console for any malformed OKs might be worthwhile.

If there’s any other differences between your gSender setup and mine (like start/stop events) that’d also be useful to know to diagnose. The stats diagnostic zip can be shared with all that info.

It is running Grbl 1.1f and I know they modified it to support a custom tool changer and pneumatic brush. So not supported at all I guess . I could not find a list of gSender supported Grbl versions from a quick search.

I noticed that it says `[MSG:Pgm End]` before the last Ok’s. Is that normal?

Thanks for the permissions and the quick reply .

Your original file works as expected on my Arduino as well, so not line ending issues.

The [MSG: Pgm end] is the normal grbl response to M30, which resets your firmware state. It’s roughly equivalent to M2, which does the same thing (resets modals, board, etc.)

I’m wondering if the M30 is causing a different board behaviours than vanilla grbl - if you removed it, does the behaviour change in gSender? Sorry, I don’t have your particular setup so this is not something I can try myself.

[kebucha]

That’s weird because in the screenshot it has stopped at line 601 and the M30 is at line 622. I can try testing without it tomorrow.

Anyways, is Grbl version 1.1f supported?
