Has anyone bought the dual filament kit from seemecnc? I have it installed and have been playing around with it. I was just wondering if anyone had any experience with it yet.
I'm not entirely sure how to tweak the settings for filament switching.

looks like a poor mans prometheus dual extrusion kit. I hadn't seen it before to day. You're looking for the "retraction on tool change" setting.

I have been playing with that but there is switching code hard coded into the firmware build.

The Bowden feeds to the splitter which is a few inches from the hotend. The tool change code retracts the filament before the splitter and then advances the other filament to the hotend.

You can alter the tool change gcode by changing the following lines in Configuration.h:
Code: Select all
#define EXT0_SELECT_COMMANDS "M117 Extruder 0\nT0\nM84 P4\nG91\nG1E172F6000\nG1E5F500\nG90"
#define EXT0_DESELECT_COMMANDS "G91\nG1E-180F6000\nG90"
#define EXT1_SELECT_COMMANDS "M117 Extruder 1\nT1\nM84 P4\nG91\nG1E172F6000\nG1E5F500\nG90"
#define EXT1_DESELECT_COMMANDS "G91\nG1E-180F6000\nG90"
