Description
Originally upload at www.thingiverse.com/thing:14421Decemnber 8th 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.
The concept is more or less the other way round. The filament pulls the syringe and squeeze the material out.

Instructions
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]
Increase the flow by changing the filament diameter.
Alternatively: In the GCode, you can use M302 to allow the extruder motor to turn without the nozzle being heated up.

Joris commented agoI think UM2 does some startup procedures which are programmed in the firmware, but.... you can set the gcode style in cura from ultimaker2 to reprap, [but not very sure anymore, haven't tested this for a long time....] then you can edit the start en endcode manually.
Ana Catarina Cabral commented agothink I got it... start generated code.. have to change it in cura, not in the gcode file.

Ana Catarina Cabral commented agoadapted the shape and now it fits in the UM2! YEY! but having trouble with the gcode.. cannot find out where the command that feeds material, to clean up nozzle in the start, is hiding... already deleted a couple of lines of code that I thought were responsible for that, but it still happens... do you have a gcode file you can send for comparison? best, Ana
Ana Catarina Cabral commented agoCool! I'll give it a try ;)
Joris commented agoYes, chocolate paste...
It should work for the UM2, but the moving head is a bit smaller so you might need to adjust the files a bit.
Ana Catarina Cabral commented agoIs it just nutella you are printing with?
I can see it's a Ultimaker Original in the pictures. Should be ok to apply it to a Ultimaker 2 instead, right? Best, Ana
