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
  • PrusaFirmware
  • Klipper
  • Smoothieware

Example

It converts this:

Send: G29 T
Recv: echo:Home XYZ first

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 libatlas3-base
    to get the plugin to load.
  • System Command Editor and Custom Control Editor plugins have a known issue here and here where your customizations for those plugins get wiped when used in conjunction with Bed Level Visualizer and a few other plugins. To avoid this from happening to you disable Bed Level Visualizer and after restarting OctoPrint configure your customizations in those plugins and save. Immediately disable those plugins and re-enable Bed Level Visualizer restart OctoPrint and Reload. Your customizations to controls and the system menu will still remain and the bug that exists in those plugins will be prevented from clearing your customizations. I highly recommend you take regular backups as well.
  • 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.

Most recent changelog

1.0.0 (11/20/2020)

Added * release channels for OctoPrint 1.5.0+ for future rc testing, similar to OctoPrint as described here

Updated * think it's time to go to major version 1.0.0 now with over 19K known installs * knockout sortable library for OctoPrint 1.5.0 compatibility

Fixed * knockout binding issue due to knockout version update to 3.5.1 in OctoPrint 1.5.0 * issue relative to using center origins and odd numbered mesh grid * issue with misinterpretation of bed level correction matrix * typos in reverse direction hover text * turn direction label coloring when direction is reversed

All releases


To-Do

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