Drawing Machine

This project was a learning process for learning to build a working machine almost from the scratch. However, since this was my very first assembled machine ever, I had to jump between several instructions and make a lot of extra work to understand every step they described. Therefore, I tried to include everything into these instructions for being helpful and convenient to create this machine even if you are a beginner.

This drawing machine is a small three-axis robot that controls a pen over a canvas. For moving the horizontal x- and y-axels, the machine uses a single belt and two stepper motors in a configuration called h-bot, and the third one for moving the vertical z-axel (pen) up and down. For drawing or writing, since the pen orientation is variable, it is possible to use regular ballpoint pens, fountain pens or felt-tip pens. For building the machine, I used 3D printer, recycled parts as much as possible, and ordered some of the parts from e-commerce. My operating system is Windows 10.

As a starting point, I used instructions made by cyul (https://www.thingiverse.com/thing:1514145) and misan (https://www.instructables.com/id/4xiDraw/).
In addition, the tutorial videos made by 3DMake (https://www.youtube.com/channel/UCRhkN6gZW62WmhAbPMKPoFA) and
MiguelBi (https://www.thingiverse.com/thing:2401997) were a great help during the assembling phase.
For sure, the greatest help and support I got from wonderful staff in FabLab Silkeborg (http://campusbindslevsplads.dk/index.php/fablab/), where this machine was built.

By making this drawing machine you can learn some basics of digital fabrication and robotics. The project develops an understanding of hardware, firmware, and software. It involves 3D printing, ordering or recycling materials, mechanical and electronic assembling including soldering and simple wiring, and setting and adjusting firmware and software.

Pay attention to rotate the 3D printed parts appropriate before printing since some of them seem to be in wrong orientation after uploading.
