[FR]: RF2000 support

[gergap]

The firmware of my printer (Renkforce RF2000) is based on Repetier.
It supports bed scanning and can output the bed matrix like this using the GCODE command M3013.
See also https://www.rf1000.de/wiki/index.php/GCodes

On the Octoprint terminal this looks like this:

Send: N10 M3013 P1*98
Recv: ok 10
Recv: M3013: current heat bed z-compensation matrix:
Recv: front left ... front right
Recv: ...        ...         ...

Recv: offset = -193 [steps] (= -0.15 [mm])
Recv: warpage = -453 [steps] (= -0.35 [mm])
Recv: g_uZMatrixMax[X_AXIS] = 10
Recv: g_uZMatrixMax[Y_AXIS] = 13
Recv: g_nActiveHeatBed = 1
[...]
Recv: ok 11

M3013 P1 outputs this in [mm], without the P1 is in [steps]. I guess [mm] is more useful.

The plugin is not able to understand this. Is there a way to make this working?

When using the commands for "GCODE Commands for Mesh Update Process"

@BEDLEVELVISUALIZER	; instruct plugin to start recording responses from printer.
M3013 P1		; report the bed leveling mesh points.

I get this error:

TypeError: Failed to execute 'uniformMatrix4fv' on 'WebGLRenderingContext': Overload resolution failed.
Received Data: [object Object]

which is most likely because it cannot interpret the firmware output correctly.

[jneilliii]

It would require some changes I think. Could you enable debug logging in the plugin's settings, restart octoprint and then do an update mesh process. Then share the plugin_bedlevelvisualizer_debug.log file from the logging section of OctoPrint's settings.

[gergap]

Here is the log file. Doesn't contain much helpful info, though.

plugin_bedlevelvisualizer_debug.log

[jneilliii]

I may have it working with the above commit. If you don't mind installing by copying/pasting the URL below into plugin manager > get more > ...fromURL and clicking Install and reporting back that would be great.

Thx a lot. We are almost there ;-)

Hi can also see data now in the plugin:

So maybe parsing is OK now, but the negative coordinates seems to be wrong. The printer has a little weird origin. Is it possible that the plugin has troubles with this negative y-coordinate?

[jneilliii]

Yeah, it's as i expected. The one line Recv: ... ... ... is getting matched and recording ['.', '.', '.', '.', '.', '.', '.', '.', '.'] as part of the mesh. Will have to figure out a way to remove that or not detect it as mesh data.

[gergap]

Hmm, not sure where these dots come from.
Here is the Perl code I used to parse the data and plot using GNUplot.
Maybe the Regex works for you too.
bedlevel.tar.gz

[jneilliii]

yeah, that's similar to what I'm already using here, but since I'm supporting all kinds of firmware have to handle it slightly different and can't include the ;.

[gergap]

I have no idea why, but it's working now ;-)

Thanks for your help. If I should test more and send you a log, please let me know.
I'm happy now 👍
