I recently got my D-Bot set up with Volcano/Titan Aero combo. I've printed a few things and they all have the bump issue, but more concerning is there is this run after the bump where it looks to be under extruding. I've tried tweaking my coast (0-2mm) and extra restart (0 through -2mm) without much success. Anyone have any suggestions? Maybe there's a certain combo of the two that works better?
