Testing firmware 3.6.90 - Do not install, use the stable version instead.

[Daid 304]

There is a firmware version 3.6.90 currently available as testing. However, this update has nothing of user value. We are currently testing a newer linux kernel (as the one we have has some nasty bugs)

However, this new linux kernel exposes a old bug that has been popping up occasionally. But with a much higher frequency. The main problem is that your printer stops printing if this bug happens. We are currently using this testing version internally to diagnose the problem, but that means the testing version has stability problems.

The 3.6.9 testing version fix the need to reboot the UM3 after each print (no file found on the USB stick).

I have an ERR18 with only one UM3 and only one printcore, is it a possible issue of the 3.6.90 version ?

[Daid 304]

I said. Do not run the 3.6.90. There is nothing for you there, except for extra strange problems.

The USB fix is in 3.6.3 on stable. (3.6.2 was the one with the USB problems)

Maybe there should be a more general feedback to users, since I hardly believe that users come here daily unless they have an issue.

So maybe adding a text explaining to what they are updating might be helpful if the testing beta is know to have serious problems.

There's room on the screen for a minimal txt, and scroll to add more lines, the um3 even can show png on the screen, so...

I'm actually here cause of a problem:

After updating to 3.6.90 the printer is not recognised by Cura for network printing (LAN on MacOS 10.12). The printer shows a connected LAN-Cable and also has a valid IP-Address. The printer is pingable.

After reading this, i'm going back to stable

@neotko Maybe we could do that but we've recently created an internal version that is only available here... So I would expect the testing version to become a bit more stable in the future.

As currently we pushed a release to testing when it needed to be installed on multiple machines in the office
