Convert a Fabrikator Mini into a drawing plotter

Pen holder for the fabrikator mini (aka tinyboy) to be attached to the back of the extruder (closer side to the Y motor)

Can be used with the
cura.ini profile for converting images to gcode. then import the code into repetier, and it works fine.


Make sure in Repetier gcode editor, or in cura before exporting the gcode, to manually eliminate the homing movements just at the start of the code because the pencil will be stopping the Y and Z axis before it can touch the end-stop controller, making otherwise the motors lose steps. You would have to set up manually the zero point, at least for Y and Z, using command: G92 X0 Y0 Z0 (optionally @isathome)
see more here about setting zero manually on fabrikator-mini or any other reprap based machine on this:
reprap forum thread.

These are the two files I designed at onshape for which you can adapt the pen diameter/hexagon dimensions, then export to STL from onshape website:
