I've just downloaded 1.2.6 and noticed that infill in particular was printing in a slow and jerky manner.

Looking at the generated code, there are a whole bunch of G4 - Dwell instructions in there;

Is there a new option I've missed that's causing this? There's not pre or post layer change G-code showing in the printer settings.

I really don't think so.

Run fan if layer-time < 60 seconds

Slow down if layer-time < 10 seconds, which should slow feedrate, not add pauses!

Thanks, that seems to have solved the issue. It wasn't having any effect in 1.2.1 and I knew it was being deprecated, so hadn't checked it.
