    On my Wanhao i3 v2.1, with ramps 1.4 upgrade, latest Marlin rc-bugfix firmware, bltouch auto leveling, microswiss hotend, upgraded extruder gear, thicker build plate, glass bed with PEI sheet, external mosfet for the hotbed, and octoprint.

    Bridging with pet-g was working... until I did the upgrade to the Titan Aero.

    What works:
    First layer
    X, Y,and Z calibrated prints measure within .01 'm
    Top layer

    Whenever I go to bridge, it just doesn't. LOL
    On the 20'm shallow test cube:
    It starts to bridge, when the extruder finishes the bridged extrusion, it doesn't stay connected and then stays stuck on the extruder as it attempts to do the next bridged extrusion. If I put enough layers, it will eventually bridge the entire top but it looks really bad and bumpy.

    Tried cura and simplify3d to create the code file. I've tried:

    Extrusion multiplier
    Different fan speeds
    Different hot end temps
    Different speeds
    Retraction settings
    Skin overlap
    Top pattern
    Alternate extra wall
    Many... Many...Many...Many iterations of different settings from above.

    My thoughts are that the settings within cura and simplify 3d are more tied to the hotend/extruder than anything else. Could some of you please post your cura or simplify3d profiles and which filament type it's for?

    Thank you,

    you say you tried skin overlap, but did you try infill overlap? that is the setting you should be tweaking.

    Off topic- do you have design files for your extruder mount including bltouch? Something I'm looking to add...
