parametric Filament-splitter
thingiverse
Still getting comfortable with openSCAD, so I decided to create this parametric filament-splitter for dual-material-prints with a single nozzle. This is an ongoing work-in-process and sometimes I am still struggling with jams (especially when the filament enters the hotend). Good luck! How I Designed This The following script is designed for Simplify3D (@ToolChange Script) to change the filament and purge the nozzle. You have to set the values for retract and feed according to your needs. T[old_tool] G1 X-70 Y0 F6000 ; move to purge position G92 E0 G1 E-20.000 F12000 ; retract G1 E-30.000 F1200 ; retract G1 E-130.000 F12000 ; retract T[new_tool] G92 E0 G1 E110.000 F900 ; feed 11cm G1 E120.000 F420 ; feed 1cm G1 E140.000 F240 ; feed 2cm G92 E0 ####################################################
