4xidDraw

The 4xiDraw is a diy xy plotter made from off the shelf materials and 3d printed parts. Perhaps it is a drawing machine more than a plotter. It can use regular felt-tip pens, ball pens or fountain pens as pen orientation is variable. It is a new version of an XY plotter using a single belt and two stepper motors in a configuration called h-bot. 4xiDaw instructables page

The plotter is Arduino based, and uses a special flavour of GRBL software created by the robottini user. It enables GRBL to handle a servo on digital pin 11 using commands M3 and M5. This way it can raise and lower the pen on the paper. Find the GRBL version here: servo GRBL
