Height Map recall

ay to verify what height map is being used if one is called before a print?

I am coming with the same question. On duet wifi 2, I upgraded to 3.01-RC9 and Duet Web Control 2.1.4 but loading the height map either with G29 S1 or through the Dashboard tab -> Compensastion & Calibration -> Load saved height map from SD Card the "Disable Mesh compensation" remains disabled.

I see in the diagnostics the following even after I Execute G29 S1 or G29 S2

=== Move ===
Hiccups: 0(0), FreeDm: 169, MinFreeDm: 169, MaxWait: 0ms
Bed compensation in use: mesh, comp offset 0.000

Is this an issue with my configuration, some bug or anything else? I can see the height map from the height map tab but cannot tell whenever it is active or not even if i turn debugging on/off.

@nickpgre I can confirm that, it will be fixed in the next DWC version.

Thanks @chrishamm !

The only way to figure if it could be loaded, was to load the height map before homing so to get the warning message!

Have a good day!

There are a couple of indicators:

When you click on "Compensation & Calibration", the popup menu displays the current compensation type.

If that shows that you are using a heightmap, you can see on the Heightmap page what the loaded heightmap looks like (provided you are using 3.01-RC7 or newer)

Actually, you only see what's in the file "heightmap.csv" not necessarily what was loaded, at least by my testing.

If I start with no heightmap loaded and no heightmap.csv, DWC shows "File 0:/sys/heightmap.csv not found".

If I do a G29 S1 P"heightmap-hot.csv", the DWC will automatically update and show the map but if I refresh, it goes back to "File 0:/sys/heightmap.csv not found".

I also note that move.compensation.file is always NULL in the DSF OM and missing altogether in the RRF OM.

On RRF 3.01-RC9+1 (duet3 standalone):

4/22/2020, 10:15:26 PM	m409 K"move.compensation.file"
{"key":"move.compensation.file","flags":"","result":"0:/sys/heightmap.csv"}

; after running : G29 S1 P"another_map.csv"

4/22/2020, 10:19:23 PM	m409 K"move.compensation.file"
{"key":"move.compensation.file","flags":"","result":"0:/sys/another_map.csv"}

Well, that's quite odd...

M115
FIRMWARE_NAME: RepRapFirmware for Duet 3 MB6HC FIRMWARE_VERSION: 3.01-RC9+1 ELECTRONICS: Duet 3 MB6HC v0.6 or 1.0 FIRMWARE_DATE: 2020-04-22b1
G29 S1 P"heightmap.csv"
Height map loaded from file heightmap.csv
m409 K"move.compensation.file"
{"key":"move.compensation.file","flags":"","result":null}
G29 S1 P"heightmap-hot.csv"
Height map loaded from file heightmap-hot.csv
m409 K"move.compensation.file"
{"key":"move.compensation.file","flags":"","result":null}

OK maybe it's just me.

SBC vs standalone?

No idea, but seems like a bug. @dc42?

Maybe. I'll create a separate thread for it.

To update DWC to 2.1.5 do I not just upload the .zip like I do for RRF? After I do this the status on the general tab does not change from 2.0.4.

Yes, you should be able to. You can also do it manually by pulling the SD card and using a PC to extract the zip file into the /www folder.

Try uploading DWC version 2.0.7 first. Maybe it's too out of sync.

Thanks! Updated RRF and DWC to the latest RC and the height map is now displaying properly.
