Octoprint Bed Visualizer G-Code  

Re: Octoprint Bed Visualizer G-Code

I tried installing this on the Pi0 but can't get it to work.

Re: Octoprint Bed Visualizer G-Code

If you go into Settings > Plugins there should be an option to install a new plugin and choose from URL. Then paste this URL in: https://github.com/PrusaOwners/OctoPrint-PrusaMeshMap/archive/master.zip

One warning, it takes a long time to install (30-45 minutes) and during this time it will look like it isn't doing anything. Just let it go and it will let you know when it is finished.

Do I have to manually install matplotlib and numpy beforehand, or does the link install them as well?

Thanks!

Install worked for me now,

tested, image only refreshes after changing color in the settings.

Got 0.32 ~-.032 @ 70c total bed variance 0.595mm I don't know if that's good or not.
And @ 85c 0.691 Front right is the high point.
Might sand the stand a bit.

I installed the plugin, but it is not outputting the heatmap image.

It runs the g-code, but does not show an image once it is finished (even after clicking reload heatmap image)

Re: Octoprint Bed Visualizer G-Code

Nope it doesn't in some browsers - Firefox / Waterfox in particular, if you come out of it and then open it again your map will appear as if by magic. This issue doesn't exist in IE (Internet Explorer). I have no other browsers loaded.

If you are using NoScript, Adblock, or UBlock you need to whitelist your octoprint instance.

Re: Octoprint Bed Visualizer G-Code

I'm using Chrome and that doesn't refresh either.

What was the gcode you used please?

RE: Octoprint Bed Visualizer G-Code

I see this is an older post, but I have both "Bed Visualizer" and "Prusa Mesh Level" installed, and I used the following for the Gcode on my MK3S:

Bed Visualizer:

G28 W ; home all without mesh bed level
G80
@BEDLEVELVISUALIZER
G81

Prusa Mesh Level (didn't change - used default):

G28 W ; home all without mesh bed level
G80 ; mesh bed leveling
G81 ; check mesh leveling results

I also had to add my Octoprint IP to the whitelist in uBlock Origin to get the heatmap to load for the Prusa Mesh Level to load the image (as mentioned by another post above).

I know this almost two years old, but I wanted to say a HUGE thank you. I am not that familiar with machine code and had a very difficult time making the Bed Visualizer actually return the results until I found this post. Huge thanks!

I tried to install that on a Pi3A+ (my OctoPrint Pi), and that has only 512MB RAM.
First there were many of these messages:

Building wheel for numpy (PEP 517): still running...

Finally the Pi did hang up, was pingable but ssh into did not work.
After power cycling no PrusaMeshMap plugin was installed.

I did install "Bed Visualizer" plugin before from Plugin Repository, and that works.
There was gcode to copy, for "Prusa Firmware" and "Prusa Mini".
Since I have a Prusa MINI+, I chose the latter option:
https://github.com/jneilliii/OctoPrint-BedLevelVisualizer/blob/master/wiki/gcode-examples.md#prusa-mini

MINI+ did a bed leveling, and then showed below map.
Not sure what the map will tell me, though.
Are the reported min and max values in millimeter unit?
Is 0.531 difference between min and max good/bad?

Here are some settings that work well for the Prusa MK4.
