UltiPlotter, plotter head for the Ultimaker2

thingiverse

WARNING ! IF YOU USE THIS HEAD WITH THE DEFAULT UM2 FIRMWARE, IT WILL CRASH INTO THE FRONT OF THE PRINTER AT PRINT START ! ALWAYS LEVEL YOUR BED AFTER A HEAD CHANGE. This plotter fits the Ultimaker 2 modular printhead: https://www.youmagine.com/designs/modular-printhead-for-ultimaker2-v2-2. Unlike in a normal ballpoint, in this thing you need to place the spring at the back of the pen. I modified my firmware to keep away from the edges of the printer a few cm more during print start and bed leveling, which is where I learned how; http://umforum.ultimaker.com/index.php?/topic/6436-more-information-during-print/?p=96906. Use Cura to load a photo, with total height around 0.8 and layers of 0.1. Other settings after picture import are as follows: Z hop at 3 mm, cut off object bottom (play with this depending on the picture, look at layer view), nozzle size (this determines the distance between infill lines). One photo shows results with a 0.4 nozzle, the other with a 2.5mm nozzle. When starting the print, just dial bed temp and nozzle temp to zero and the printing will start. This article provides information on using a Cura setting file but I did not use it; https://ultimaker.com/en/stories/view/99-transform-your-ultimaker-in-a-desktop-pen-plotter.
