Hey Guys,
i've designed for my printer a panning dual hotend. It can lift the unused nozzle, so there isn't a contaminant of the printed filament an no oozing. The filament cooling is integrated as an air duct in the slider. You've to print the parts careful. They have some critical points.
Furthermore you need some purchase parts:
2x 50mm Fans
3x IGUS RJMP-1-8 Linear Bearings
1x Graupner DES586BB Digital Servo
Some M3 & M4 Screws
2x Hotends
2x Aluminium bracket 30x30x2
1x LJC12A3 Proximity Switch
Some Hot-Temperature Silicon
You can watch a video oft the prinhead in action on youtubehttps://www.youtube.com/watch?v=6Enaf-HHfRo
Note:
It could be, that the nozzle moves not to the limit stop. So the servo isn't strong enough to bend the cables an the filament PTFE tubes. Make the cable loop a little bit bigger and take longer filament tubes
Software implementation
There are two ways to implement this in Software:
The first easier way is, to use in slic3r a tool change command like this:M340 P0 S[next_extruder]…
