Octoprint Bed visualizer Plugin

Hi guys,

I have installed the Bed Visualizer Plugin and added

G28
M155 S30
@BEDLEVELVISUALIZER
G29 T
M155 S3

to the commands. But I have no idea about what to do next or how to start the visualization. Please help me with that, complete noob here

once you've added your settings you'll possbly need to restart octoprint once and then press the button. The plugin does assume that your printer supports auto bed leveling (probe of some sort, or manual mesh leveling).
