Ortur LM2 connexion issue

[themaire]

Hi. I am Nicolas from France.

Describe the bug Octoprint can't connect to my Ortur LM2. Error:20 the 1st time when the laser is fresh booter then error:9 when I retry to connect.

To Reproduce Steps to reproduce the behavior: 1 : Installed last OCTOPI distro -Version 0.18.0, running on Raspberry Pi 3 Model B Rev 1.2 Octoprint Version 1.7.2 2 : Installed Better Grbl Support (2.1.1) then rebooted the system to be "safe". I am surprising, the temperature, control and GCODE tabs are not hidden. And, the only lines who talk about the plugin in config.yaml are ( in the plugin section ) : bettergrblsupport: _config_version: 4 wizard_version: 2

3 : Go to the Octoprint's settings and discover Features > Send a checksum with the command is still in

Expected behavior

Additional context I think the plugin is not correctly installed.

Thanks a lot by your attention. Nico

Definitely does not sound like it is installed correctly. Is "Grbl Control" showing up as a tab?

Do you mind sending me your octoprint.log file? I suspect there may be an error in there I need to look at.

[synman]

QQ -- by what means did you install Better Grbl Support? Did you provide a URL or grab it from the Plugin Repository list? If from a URL, which URL did you use?

[themaire]

Hi!!!! 20 minutes to reply, it's a pleasure.

Yes the "Grbl Control" is present but not b default and is the last tab.

My octoprint.log : https://pastebin.com/LZNP7jiZ

I installed from the plugin manager > +get more button list.

Good luck. ^^

[synman]

just to confirm... no URL... you just selected from the list of plugins available?

[themaire]

Yes. Like as usual.

[synman]

this line in your log indicates the plugin is disabled:

| !Better Grbl Support (2.1.1) = /home/pi/oprint/lib/python3.7/site-packages/octoprint_bettergrblsupport
Prefix legend: ! = disabled, # = blacklisted, * = incompatible

Are you able to re-enable it in plugin manager?

[themaire]

Ok. So.

It was marked as "Enabled". I clicked to disable > restarted Octoprint > enable plugin > restarted Octoprint. Everything is at the same point.

[synman]

the log file you shared was also only 60 or so lines.... do you have a complete log file you can share?

[themaire]

I was the full log because the install was extra fresh. Can I try to remove the plugin and re install via the GitHub repo URL?

[synman]

yes, please uninstall it... but just download it again from the list provided. I just did a fresh install myself and was able to proceed with no issues following this procedure.

I'll need to see your log file again too.

[themaire]

Edit... for extra information ; Octoprint is installed via the Raspberry Pi Imager. Octoprint selected into list.

OK. This is the log of the plugin re-install : https://pastebin.com/dKxcSiVC

I have the temp, control and Code Viewer non hidden tabs.

Thanks

some good signs here:

Another good sign...

| Better Grbl Support (2.1.1) = /home/pi/oprint/lib/python3.7/site-packages/octoprint_bettergrblsupport

gut tells me the last log just showed the status post install but before the required restart.... plugin is active....

some weird news....

| GCode Viewer (bundled) = /home/pi/oprint/lib/python3.7/site-packages/octoprint/plugins/gcodeviewer

this guy should be disabled...

and bingo (pardon my American English slang) .....

Traceback (most recent call last):
  File "/home/pi/oprint/lib/python3.7/site-packages/octoprint/plugin/__init__.py", line 271, in call_plugin

FileNotFoundError: [Errno 2] No such file or directory: '/home/pi/oprint/lib/python3.7/site-packages/octoprint_bettergrblsupport/static/txt/__bgs.profile'

So here's the heart of our issue.

Now I need to figure out how the default profile is missing.

[synman]

do you mind showing me the output of the following command?

ls -la /home/pi/oprint/lib/python3.7/site-packages/octoprint_bettergrblsupport/static/txt

[synman]

wait, I may not need it after all.... how in the world did I miss this:

FileNotFoundError: [Errno 2] No such file or directory: '/home/pi/oprint/lib/python3.7/site-packages/octoprint_bettergrblsupport/static/txt/__bgs.profile'

There are two _ characters there.... the actual profile file only has one.... OMG

yup.... I screwed the pooch

will have this fixed shortly.

        if not os.path.exists(dest):
            src = os.path.dirname(os.path.realpath(__file__)) + os.path.sep + "static" + os.path.sep + "txt" + os.path.sep + "__bgs.profile"
            copyfile(src, dest)

[synman]

this went directly to master.

2.1.2 should be available for install via Software Update..... click "Advanced", "force check" to accelerate the process.

@themaire (Nicolas from France) I also left you an Easter egg in the release notes :)

[themaire]

Hi!! Crazy, it works. You rock. Thanks you again.

Machine is able to connect and all is working fine. In the past I stoped to use you plugin because of various error:20. Now I am here to report all will goes wrong.

Have a nice day!

Nicolas.

about to release 2.1.3 with a few more bug fixes and added features
