[Help Needed] Octoprint PrushMeshMap Plugin

Hello Everyone,

The Plugin:

In the process of leveling my bed manually, I wrote a Python script ( https://github.com/ff8jake/g81-to-heatmap ) to decipher the G81 output into something a bit more human. Like this:

Many of you liked it, and I received a few requests to turn this into an Octoprint plugin. So I did. 🙂

I know many of you really want to tweak with this, including things like measuring after getting your PINDA up to temp. So I added the option to customize the gcode:

Finally, I have also made this in such a way that it constantly watches the output coming back from the printer. Any time a G81 happens (via the script above, or via a nice G81 inserted into your Slic3r start scripts!), it's going to recalculate the heatmap. You'll just need to go to the Prush Mesh Level tab, click reload under the heatmap image, and see what your last G81 results were. This will be very nice for troubleshooting. Have a crappy first layer? Go check that last heatmap and see what the PINDA thought on that particular print. 🙂

How to Use it Yourself:

I haven't put this on the Octoprint Plugin Directory yet because I want to battle test it a bit more and get some more ideas from you guys first. If you run Octoprint and want to give this a shot, do the following:

  • Log in to Octoprint,

  • Go to Settings > Plugin Manager,

  • Click the "Get More..." button at the bottom of the plugin list,

  • Scroll down to "... from URL" and paste in: https://github.com/ff8jake/OctoPrint-PrusaMeshMap/archive/master.zip

  • Click Install, and when it finishes restart your Octoprint server.

    • Ideally this all works correctly and you'll have the "Prusa Mesh Leveling" tab at the top. You must have your printer connected to perform a mesh level operation. The image WILL NOT update automatically after doing this. This is somewhat intentional, as it's sloppy to have javascript constantly refreshing it and it makes sure you are able to see a quick before/after by clicking the reload button below the image.

    You can go to Settings > Prusa Mesh Leveling if you'd like to adjust the gcode script to include heater settings, PINDA warmup, etc.

    Help Wanted:

    This is my first Octoprint plugin. I do Python work as a Linux Sys Admin as needed at work and whenever my hobbies call for it. If anyone here has Octoprint plugin experience, please PM me an example and I may throw you directly onto this project. Of course, if you are only wanting to add some one off changes or improvements, it's on Github so you can fork and make a pull request as well. Issues and feature requests are also welcome and appreciated.

    Github Repo: https://github.com/ff8jake/OctoPrint-PrusaMeshMap

    Thank you guys for your help!

    I'll be adding this fellow to my octopi as soon as I get a chance. (middle of a 12 hour print)

    Can I request a feature.

    Record the tests, and have an option to "average" them. (I know you complain about the consistency of the PINDA... this request is more for you than me... ;))

    Hi, I'm Sean. I used to work on CNC machines.
    I try to not make mistakes, but the decision is YOURS.
    Please feel free to donate to my filament/maintance fund.

    Already bumping this from 0.1.0 to 0.1.1. Had an absolute URL in one spot that would have worked for me and nobody else. If you installed, I think you can just install again (fom URL) to fix.

    Thanks

    Yeah that's a common issue. Need to get a second or third MK3 to fix that. :mrgreen:

    Added the plug-in without issue, however, I neglected to power the printer on before I left the house this morning so I can't test.

    Thanks for your attempt, I think I have a workaround. Please try the following:

  • In OctoPrint, go to Settings > Plugin Manager,

  • In the top right corner, click the wrench icon,

  • In the "Additional arguments" box, add the following:--no-cache-dir

  • Click "Save" and try the plugin install again. 🙂

    • From what I am seeing, this error happens from time to time with pip on low memory systems (not specific to my plugin). The above argument seems to fix it in most cases I find. Also, if you find this fixes your issue, can you please confirm your experience on the following Github issue? https://github.com/ff8jake/OctoPrint-PrusaMeshMap/issues/3

    Thanks!

    Dang, I guess this is what I get for running OctoPrint in docker and not trying this out on a Pi before release. A post or two back I put the --no-cache-dir instructions, guessing this is with that plugged in?

    I have a Pi 3 B+ at home I can test with later, but it's looking like this is strictly pip issues on the Pi. You may be able to install these requirements by hand via SSH, if you'd like to see if you have any better luck:

    pip install matplotlib numpy

    Those should be the only pip packages the plugin will require, and pretty much the same command OctoPrint is running.

    Nah, I have a Dell R520 server that I run KVM on. I've got a virtual machine there running Docker that I am passing USB through to, then passing that into an OctoPrint Docker container. Works pretty nicely. 🙂
