height map not displaying in Firefox

jrsphoto

I've got an Ender 3, with a Duet 2 Wifi that has been working flawlessly for 6 months or more. I had printed something yesterday and everything went well. Today, I went to print and issue a G29 and make sure things are in order before printing. G29 replies with:

30 points probed, min error -0.089, max error 0.089, mean -0.018, deviation 0.049
Height map saved to file heightmap.csv

So things look OK. But when I go to the Height Map page, no height map is displayed. Its just blank

I did notice something odd though, the date on the heatmap.csv file (system directory) was like 6 months old. So I deleted the old heightmap.csv file and did another G29 and got the exact same output. Even the part about saving the results to heightmap.csv, except there is no heightmap.csv file in the system directory. I thought the system would have recreated the files but maybe I'm missing something?

Other pertinent information:
I updated to DWC 2.04 and 2.05RC1 and that seems to have had no effect

My Config.g

M557 displays: Grid: X45.0:193.0, Y30.0:193.0, radius -1.0, X spacing 32.0, Y spacing 32.0, 30 points

Duet WiFi 1.02 or later
RepRapFirmware for Duet 2 WiFi/Ethernet 2.05RC1 (2019-11-29b1) - updated to this today trying to fix the problem.
Duet WiFi Server Version: 1.22

After powering off the board, it did create the new heightmap.csv file, but still, no heightmap is displayed in the Height Map page

Also just updated the Duet Wifi Server from 1.22 to 1.23. No effect on my inability to view the height map.

So I decided to try another browser. I had been using Firefox, but just now tried Chrome. This works. So am I dealing with corrupt cache? I'll flush cache on Firefox and try that

jrsphoto

I've cleared all the cache from Firefox and it still won't load the height map. I'm stumped at this point.

I've modified the title and moved to the DWC forum.

If you open the debugging console (usually control-shift-J AFAIR), are any JavaScript exceptions shown?

jrsphoto

These are the errors I'm seeing now from the developer tools, console tab. For the heck of it, I booted to linux mint and tried things with firefox there. Thinks kind of worked but when I went to extrude 20mm of filament, it would do the extrusion but the buttons for extrude/retract, would change to a spinning icon and never come back.

That's a known issue between DWC2 and RRF 2.05RC1. It will be fixed in 2.05RC2.

With luck, @chrishamm will be along to reply to the height map display issue.

jrsphoto

@dc42 Thank you. I'll wait for his reply.

It looks to me as if WebGL is disabled somewhere in your Firefox settings. I just created a new heightmap file and tried to display it and that worked without problems for me.

I suggest you open about:config and search for "webgl.disabled". Make sure it is set to "false". If that's the case, I suggest you reset your Firefox profile and try again.

@dc42 I got this morning same problem. Chrome, DWC 3.2.2 on firmware 3.3 wnd DWS 1.26.
I enable Webgl as found lower in this post, checke my config which was same as always, but the problem for some reason is here.
On Crtl/Shift/J it gives me:
Error: Invalid Height Map
at new ExtendableBuiltin (app.56671d18.js:42)
at InvalidHeightmapError._createSuperInternal (createSuper.js:12)
at new HeightmapError (errors.js:99)

at VueComponent.showCSV (HeightMap.vue:283)

at tryCatch (runtime.js:63)

Any ideas why? I found the csv and i even run a new G29 and it updated the info, but it does not show

dc42

@tonygr update DWC to 3.3 to match the firmware version.

TonyGR

@dc42 i thought there was not a 3.3 since i used the complete Zip to update. I did standalone the dwc to 3.3 and worked great. Thank you
