Hot end temp not responding after extended idle

I've been seeing an issue with the hot end not responding to temperature changes via DWC or M104 after an extended idle period. (overnight).

It starts responding again after power cycling or issuing m999 command.

Bed temp changes are working

I think this may be an issue in the beta you are using that is fixed in the later ones. Either update to one of those or wait for RC1 or roll back to 3.3.

@phaedrux

I think this version has improved PID tuning and made a big difference in another problem I've been experiencing.

Can you link most current beta? Or better yet... Is there a permalink to the repository? I keep getting dropbox links which go stale plus i cant just modify the URL to navigate up some sort of directory tree.

Thank you!

Yes it's a bit unusual to have so many hotfixes on a beta.

These should be the 7+7 files I think.
