I’m trying to trouble shoot this problem which is occurring on some of my larger (~ 160mm) prints.
I am thinking it has to do with the default extrusion width in slic3r. I was using some of lulzbot’s profiles but making some changes to the speed, layer heights, and various other settings and didn’t realize that the extrusion width was set to something besides 0. So this print might not have had an optimal extrusion width.
However it could be something totally unrelated. I’m thinking it might be related to printing with a brim?
Also you may notice on the long, flat side of the object the layers are warping a bit as we travel up the z. The lower layers seem to be cooling at a different rate. This effect was much mroe pronounced when I was running the heated bed at 110C instead of 85C now.
; layer_height = .25
; perimeters = 4
; top_solid_layers = 5
; bottom_solid_layers = 5
; fill_density = 0.2
; perimeter_speed = 80
; infill_speed = 120
; travel_speed = 200
; nozzle_diameter = 0.35
; filament_diameter = 2.89
; extrusion_multiplier = 1
; perimeters extrusion width = 0.36mm
; infill extrusion width = 0.36mm
; solid infill extrusion width = 0.36mm
; top infill extrusion width = 0.34mm
; first layer extrusion width = 0.30mm
Any thoughts on why the first 8 layers or so look so much rougher than the rest of the print?
