Have a problem with mesh data that is captured when I run Octoprint bed visualizer.
In Marlin I selected bi linear for auto bedleving. Here are the commands I used to start the bed visualizer.
M140 S60 ;Heat bed to 60
M104 S205 ;Heat nozzle to 205
M190 S60 ;Wait for bed to reach 60
M109 S205 ;Wait for nozzle to reach 205
M155 S30 ;Change temp reporting to 30 seconds
G28 ;Home print head
M420 S0 ;Turn off Bed leveling
@BEDLEVELVISUALIZER ; tell the plugin to watch for reported mesh
G29 L25 F60 R178 B225 V4 ;Start Bilinear auto bed leveling
M155 S5 ;Change temp reporting to 5 seconds
M140 S0 ;Turn off Bed
M104 S0 ;Turn off Nozzle
M420 S1 ;Turn on Bed leveling
M500 ;Store new mesh data
This is the data captured and the graph is all wrong. Not sure what the first 25 lines are there for. The last 5 rows look like the correct value.
