Error on heightmap display

EHay

Something new happening.
Been trying to set maximum area to run mesh grid, but all of a sudden I am getting the following error when it tries to display the mesh grid :

Javascript Error

A JavaScript error has occurred so the web interface has closed the connection to your board. It is recommended to reload the web interface now. If this happens again, please contact the author and share this error message:

Version: 1.22.6
Message: TypeError: r is null
URL: http://192.168.0.221/js/dwc.js
Line: 15:296246
Error object: {}

It does save the height map in the Heightmap.csv file so I can still print.

RepRapFirmware height map file v2, mean error 0.071, deviation 0.097
xmin,xmax,ymin,ymax,radius,xspacing,yspacing,xnum,ynum

0, 0.155, 0.217, 0.232, 0.180, 0.072
0, 0, 0, 0, 0, 0

It errors when the heightmap is displayed and closes the connection to the duet.
I took the numbers back to the original, but it does it all the time now.

I think you may need to update your firmware and DWC versions. What are you currently running?

EHay

Firmware Version: 2.02(RTOS) (2018-12-24b1)
WiFi Server Version: 1.22
Web Interface Version: 1.22.6

Been Running for months, Have not updated anything.
I have switch to firefox recently. Did not have this problem till today.

OK, switch back to chrome just to test and it works there.
I locked a few things down in firefox for a little more security, must have changed something it doesn't like.

You may want to try updating your firmwares as you're all a bit out of date. If everything is running smoothly and changing the browser has solved the issue maybe you want to stay where you're at. Check the release notes between 2.02 and 2.05 to see if there's anything you might benefit from.

https://github.com/Duet3D/RepRapFirmware/releases/tag/2.05

If you do want to update, upload the zip file from 2.05 release to update your firmware, wifi, and DWC versions.

There is also a bug fix release for the firmware and update for the DWC in 2.05.1

https://github.com/Duet3D/RepRapFirmware/releases/tag/2.05.1

Will Check it out, thanks.
