Invalid Height Map 3.4.2RC1 Delta

[garlicbread]

Hi,
I recently updated to version 3.4.2RC1 (I think from 3.2) on a Duet Wifi2
I was going to go for 3.4.1 stable but I was a little worried about the mention of config.g disapearing in the change logs

It looks like the web viewer has problems viewing the heightmap.csv file

Contents of the file are:

0:/sys/anycubic_delta/heightmap.csv

I tried deleting the file then re-running G29 but it still seems to be the same.
Maybe it's related to me using a delta, or perhaps because I'm using M505 P"anycubic_delta" I'm not sure

The Statistics seems to show up ok though

Statistics
Number of points: 97
Probing radius: 110 mm
Probe area: 380.1 cm²
Maximum deviations: -0.626 / 0.220 mm
Mean error: -0.190 mm
RMS error: 0.234 mm

So I'm wondering if it could be a glitch in the web viewer part

What version of DWC and Duet Firmware are you actually using?

@garlicbread Here’s your height map:

Loaded it onto my Duet2 WiFi, cartesian, RRF 3.4.0.

That means: your data are entirely valid, so, in theory, only the file format can be wrong.

In order to visualise your height map, I pasted the contents from your post into a text editor (I’m on a Mac, so I took SimpleText) and converted it to plain text with UTF8 encoding, saved that and changed the file extension to .csv. Then, I copied the file into the /sys/ folder of the SD card … dunnit.

To see whether the file format of your heightmap.csv is the culprit, follow the procedure I outlined above, then see if it woks.

Ok I think I was taking for granted that Duet2CombinedFirmware.bin also contained the web interface part.

I'm noticing my web interface is on 3.2.2

I can confirm that the Heightmap file was deleted then regenerated via G29 btw. But I'll try upping the web interface first.

Yep that fixed it my bad for forgetting to update the web interface
