[FEATURE REQUEST] Bed Mesh Leveling Visualizer

[dmiart]

Is your feature request related to a problem? Please describe.

I am using an octoprint plugin called bed visualizer to display G29 T. Would be nice to have something like this in the esp3D.

Describe the solution you'd like

I basically want to be able to see this a graph like this on the web page of the ESP3D. Or at least a very basic graph that shows 4 corners and how much they differ from each other, so I know which knobs to turn to calibrate bed so it's physically as level as possible.

Additional context

[luc-github]

can you share a G29 T output ? I do not have probe for bed leveling

ok clear, thank you

I think to do this representation need user to key bed size or we can also use an virtual square just described by external probed points

[dmiart]

Is there no way to get it during the runtime from the printer itself? What about moving the hotend x and y to the max possible and then getting that position ? I wonder how that plugin does it. I suspect it takes values from Octoprint profile.

[luc-github]

Sorry I do not understand
Do you mean you Use G29 V2 ... to get it verbose and get updated report when running ? Does it work ?

[dmiart]

I am not entirely sure what you mean. That plugin does G29 T I think. For the bed size, I meant wouldn't it be possible to query the printer for that information or to force it to move as far to the right and forward as possible to determine the bed size?

my answer was about :

what do you mean ?

For bed size there is no GCODE I am aware of to get it (I think only prusa FW has something in debug mode) so I think user user need to key info

Strange that there is no M or G code for it. On second though letting user enter it would probably not be too bad since it only has to be done once.

Well there is one command in Marlin that may be used but it is not the bed size , it is endstop positions - which may differe from bed size and also need some define set in Marlin FW to work

M211
echo:Soft endstops: ON  Min:  X0.00 Y0.00 Z0.00   Max:  X220.00 Y240.00 Z130.00

Cannot find any other GCODE in Repetier / Smoothieware neither, if you can find it let me know

Hi, this is the plugin, it uses a ja library, called plotly, https://plugins.octoprint.org/plugins/bedlevelvisualizer/
You would need to take care also of bed type (delta or Cartesian printer)
At least in marlin there is information you can get with gcode related to Max print size and bed offsets, right?

[luc-github]

as mentioned above so far there is no print size but max position which even offset is defined may not give the correct bed size -
max position is not always upper limit of bed size

Also I am definitly not Marlin focused - I prefer to find solution that benefit the most

Thank you for the link I will have a look

I do not have delta printer neither auto level probe system
what the difference of bed between delta or Cartesian printer for such purpose ?

Note: I know plotly but its footprint is too big and cannot be used, gzip version of mininimal code is around 340K which is too big

@luc-github This would be a great feature if possible :-)

[luc-github]

it is set as planned, so it is in TODO list but .. not on top items, also I do not have any bltouch / probe system, so it will need to wait until I get one to work on this,

[luc-github]

Add https://github.com/plotly/plotly.js/ as reference but size is too much (several MB) so need a smaller footprint solution
