BedLevel 0.0.8 error about octoprint-bedlevelvisualizer HOT 10 CLOSED

I'm getting the same

from octoprint-bedlevelvisualizer.

Try pressing the update button once on the tab to retrieve the mesh data and store in memory.

from octoprint-bedlevelvisualizer.

That's causing the error, after pressing the button it starts running the GCODE, after the printer displays the content for G29 T, then that message appears. Was working prior to the 0.8 update.

look at the values, my mesh got bad values somewhere. I re-ran bed leveling and the visualizer is working correctly again.

These values work.

@ytymec, did that work for you?

from octoprint-bedlevelvisualizer.

Still the same issue, adding that after pressing update, the screen stay on "retrieving current mesh"...
Additional information: I'm on old Marlin version : 1.1.0-RC6

from octoprint-bedlevelvisualizer.

@ytymec: what's the output of manually sending the command G29 T?

from octoprint-bedlevelvisualizer.

Yus should set your data collector flag to Bed Level Correction Matrix:

from octoprint-bedlevelvisualizer.

It works with the latest version of Marlin 🥁
