Estrange resolution slope in Model #3129

Open Caracol-Studio opened 8 years ago

Caracol-Studio commented 8 years ago

Hello I am using Slicer 1.29, I would like to know why the result of slicing a stl file composed for 3 pieces, in the biggest one the slope of the pieces is generate as a scattering surface instead a continuous and smooth as in the STL file. I checked in the Netfabb that the pieces are corrected without corruption in the mesh. as well I have tried to change many parameter getting always the same result.

I attach link to zip with the files ( Printing Profile, Stl File, Gcode generate it ). Thanks in advance

Probably because a slicer needs to have separate layers on the slope. The stl does not.

or in other words: any slope must be approximated by steps. The smaller the layer height, the smaller the step becomes (by the cost of printing time), the better is the approximation to the .stl file.

p.s.: I did a short review of the GCODE file:why did you chose 0.4mm for the first layer (= nozzle width). Furthermore several extrusion width were selected smaller than the nozzle width, which will generate significant errors in material extrusion in slicer. My personal suggestion for the settings would be: first layer = extruded layer = 0.2mm, extrusion width default: 0.45mm, first layer width 0.6mm. Maybe you have tried this already, A further improvement would be to reduce the layer height to 0.1mm (of possible with your hardware).
