OctoPrint-BedLevelVisualizer

This plugin visualises the output from various firmware that support bed mesh leveling, noteably the Prusa G81 mesh leveling report and the Marlin G29 T bed topography report. The plugin utilizes Plotly js library to render a 3D surface of the bed's reported mesh on a tab within OctoPrint.

Supported Firmware:

Marlin 2.0.5.3
Prusa i3 MK2 to MK3S version 3.2.3 to 3.8.1
Klipper
Older Marlin and Repetier firmware.
Smoothieware

Known Issues

Install will fail silently in Python 3 due to missing system dependencies. You may have to SSH to your pi and run the command sudo apt install libgfortran5 libatlas3-base libatlas-base-dev to get the plugin to load.
Since version 0.1.3 there is a python dependency on numpy. As a result; if you don't already have numpy the install can take in excess of 30 minutes to complete on a pi. Just be patient and let it run and eventually the plugin install will finish.
If your device have less than 512MB of ram your numpy installation will most likely fail. See #141 for solution.
If you have Marlin's Auto Temperature Reporting Feature enabled you will want to have M155 S30 and M155 S3 surrounding your G29 command, see settings screenshot, otherwise the collected data will be tainted.
Currently there is a conflict with the TempsGraph plugin. If you have this plugin installed you will receive an error that Plotyle.react is not a function. There is a version update pending on that plugin to resolve this issue, just waiting on the author to release. Resolved with TempsGraph release 0.3.3.

Most recent changelog

0.1.14 (07/26/2020)

Added

chart studio button in modebar lost in recent plotly updates
configurable z limits to graph

adjust rectangular mesh for circular beds, still needs work

All releases

To-Do

improve old marlin makergear support
improve rectangular mesh for circular bed calculations
~~Pause standard OctoPrint temperature polling or squash the responses until processing is completed.~~ won't be possible, utilize M155 gcode if possible
~~Orientation testing to verify axes are in correct direction.~~ added settings to allow controlling the orientation.
~~Calculate bed dimensions and apply to probe points for display on graph, #28.~~
