[Bug]: Next Filament Change value doesn't make sense

[luizbgomide]

The problem

The value displayed in Next Filament Change doesn't make sense, I printed a lot of files with multiple filament changes and in all cases the value was either too short, or too long. I'm not even sure if it is showing time TO change or time OF change, it is very wrong in either case.

By comparison, the plugin TimeToFilament shows the values correctly and accurately (it uses PrintTimeGenius).

Here is a screenshot 23:52 doesn't mean anything here. The next change will happen at around 05:00 and that is something like six and half hours from now.

I have found the same problem. My next filament change is in about 3 hours (which TimeToFilament gets right) but dashboard shows 20:58 (as in 20hrs, 58minutes).

Seems very broken...

I will have a look at how TimeToFilament does it

I have created a fix, it will be included in the next release.
If you want to try it out before then, you can install the development branch using this url

Please note that this branch may be unstable.

Thanks, if I install the development branch will it auto-update when a new version is released?

Yes
