Support Extrusion Width

Mon Aug 30, 2021 11:00 pm

Hey y'all,

It would be super helpful in some instances to be able to dial down the extrusion width for support material, much like you can do with infill currently. In situations where I print fat beads with big nozzles, support becomes very difficult to break away. I believe that being able to print supports at half or less of the default extrusion width would make removing supports a lot easier.

This can be achieved with a post processing script in the SCRIPTS tab.

{REPLACE "; feature outer perimeter\n" "M221 D0 S100\n; feature outer perimeter\n"}
{REPLACE "; feature inner perimeter\n" "M221 D0 S100\n; feature inner perimeter\n"}
{REPLACE "; feature solid layer\n" "M221 D0 S100\n; feature solid layer\n"}
{REPLACE "; feature support\n" "M221 D0 S80\n; feature support\n"}
{REPLACE "; feature infill\n" "M221 D0 S100\n; feature infill\n"}
{REPLACE "; feature skirt\n" "M221 D0 S100\n; feature skirt\n"}
{REPLACE "; feature internal single extrusion\n" "M221 D0 S100\n; feature internal single extrusion\n"}

will give you an 80% extrusion multiplier (relative to whatever is set in the Extruder tab) for supports.
The other lines are to return the multiplier back to 1 for other feature types.

I understand you want a box where you can type a number, but if you need the functionality this is a way to get it.
