ultimaker syringe extruder II

Originally posted on Thingiverse.com: Dec 8, 2011 - Updated and improved some things to better attach to the ultimaker. Works now with 100ml syringes. Still uses the filament for 'driving' the syringe. Also new are the end stop enlargers so the endstops still work with the syringe attached.

Description

The concept is more or less the other way round. The filament pulls the syringe and squeeze the material out.

Resize the shapes suited for your syringe.
Print the syringe holder.
Print the end stop enlargers.
Screw same [ultimaker spare] m3 bolts through the holes to fixate the syringe holders to the moving head.
Attache everything.
Generate gcode
Without temperature settings
Very low extrusion speed
Open the gcode in a text editor and replace "E" with "E-"
[we want to pull the filament not push it, you can also change the firmware, but this was easier for me]
Print and use the live control panel in repg to tune the flow and speed.
