I have not yet been able to get a high quality print out of my BigBox 1.1 running RC6. I have checked the Simplify3d page and can't see the issue I'm having. I get really rough outlines and bottom layers and pretty poor layers from there on. I mesh level the bed (and store to memory) before every print. For whatever reason I still get rough prints. Things I have tried: - Bed temps from 50 to 60 degrees - Hot end temps from 200 to 220 degrees - Different brands of PLA (Verbatim & E3D everyday) - Did the test 100mm filament extrude/measure and tweaked settings I have no idea if what I'm seeing is typical "under extrusion", "over extrusion", "nozzle too close to bed" or some other issue.
