Since I started using simplify, my extruder (Airwolf 3D HD2x) jams on smaller, more intricate designs. It was able to create a large hollow rectangular shape that I was using to test the software's supports but jams after two or three layers of trying to print a boat or frog shape. When I pull out the filament there is a 'bulb" shape that is preventing the filament from extruding. I have reverted to Mattercontrol and the designs print without much issue and do not create the bulb.
So far I have tried:
-raising the temperature (210 for PLA)
-modifying retraction speed/amount
-disabling retraction altogether
-lowering exxtrusion multiplier (from 1 to .9)
-lowering infill and movement speeds
All to no avail. Wondering if anyone could provide some new perspectives or ideas. I am perplexed.
