HI team OctoPi
first of all it is awesome work, second I found a little bug:
1: Set the E0 temp to 205 trough the control tab on octoPi
2: Change filament to the wanted one
3: selected the uploaded file from the Queue, it set the E0 temp to 205
and here is the bug, when I get to gode from gCode that sets the Temp on E0 it double it up, sp the E0 temp will be 410. that is not ideal. it is as the system doesn't read that the E0 is turned on, and is this case I have set me preheat configuration as the same in my slicer, S3D
Is that something that could be look at
