The New Hotness

  • Makergear M2: Deprime Test Object

    This object from whpthomas’s collection exercises the deprime operation in Sailfish, but it seemed like it’d be useful to verify the Marlin settings in the M2:

    M2 - whpthomas deprime test
    M2 – whpthomas deprime test

    From the other side:

    M2 - whpthomas deprime test - view 2
    M2 – whpthomas deprime test – view 2

    Yes, that was rather anticlimactic. No ooze, no stringing, no surface finish blemishes, just the finished object on the build platform’s glass sheet.

    I like that!

    The slight bumps on the sharp corner edges seem to be due to the crazy-high perimeter and infill speeds I’ve been playing with, although (I think) those are also where layer changes occurred. The first layer height came out a bit short, so there’s a small flange around the object’s bottom edge; I was figuring out how to get a precise level across the entire surface and stabilize the Z-min switch operation.

    The slic3r configuration:

    ; layer_height = 0.25
    ; perimeters = 1
    ; top_solid_layers = 3
    ; bottom_solid_layers = 3
    ; fill_density = 0.10
    ; perimeter_speed = 100
    ; infill_speed = 300
    ; travel_speed = 500
    ; scale = 1
    ; nozzle_diameter = 0.35
    ; filament_diameter = 1.70
    ; extrusion_multiplier = 0.9
    ; perimeters extrusion width = 0.40mm
    ; infill extrusion width = 0.40mm
    ; first layer extrusion width = 0.39mm
    

    No source code, as it’s directly from the STL on Thingiverse; I have no idea which modeling program he used.
