DWC 3.3RC1 - Resetting controller causes connection loop.
-
If the controller is reset is reset, DWC goes into a continuous loop of re-connection.
Each time an error pops up saying m.global is null.Refreshing the page (F5) fixes it.

@owend please check using M115 that you are running RRF3.3RC1. You may also wish to try the updated RRF binary at https://www.dropbox.com/sh/dlb58vkmu1u4fkx/AAAelkXSfRKVwI6_yqRnhGHPa?dl=0.

Stand alone. -
@owend Does your config.g contain a reference to global.m? Might be worth posting it and any other scripts that run at startup.
-
@owend AFAIR there was a bug affecting standalone setups with a password set in an previous DWC versions. Please confirm that DWC displays version 3.3-rc1 on the Settings -> General page. If it does, please open the JS console via F12 when the connection loop occurs and check for potential errors.
If nothing unusual shows up, please share the output of
M122too. -

DWC version is
Rolling back to DWC 3.3b1 solves issue!
I get no errors at all.It all seems to relate to loading the global variables in DWC.
The constant is the error message m.global is null
I have tried checking if the globals exist or are null in config.g and added a wait G4 P10 after creating each global.
I've tried removing any spaces around global names and calculations.At times I can get it to reset without the looping, but the null global error always persists.
Happy to arrange a team viewer session if that may help debug.
This is my original config.g (before upgrading to 3.3RC1

If I watch the object model browser while performing an E-stop from DWC, I can see the root level global array become null in 3.3RC1.
Whereas in 3.3B3 it does not

@owend Thanks for reporting this, I've got a fix ready. It will be part of RC2.

@chrishamm said in DWC 3.3RC1 - Resetting controller causes connection loop.:
@owend Thanks for reporting this, I've got a fix ready. It will be part of RC2.
Just a note that this persists in 3.3RC2

@owend Thanks, I can confirm there was still a minor bug in DWC, although it does not cause disconnects any more on my setup. It will be fixed in the next version.
