5. BrachioGraph

   4 4 714 5.2 Python

   BrachioGraph is an ultra-cheap (total cost of materials: €14) plotter that can be built with minimal skills.

   

   Reminds me of the https://www.brachiograph.art/ . I tried to replicate this, but found the position drifted and jittery.... Probably due to poor glueing technique...

6. x-scara

   SCARA CNC and 3D printing machine

   

   For a more refined machine, there is the XScara[0], a DIY SCARA 3D Printer that can be used for more than 3d print. I made one and change the 3d print head with a laser system, and also had a pen that can be used as a plotter.

7. Quincy

   6 1 24 - C

   Opensource software for the Landzo Quincy Drawing Robot Artist (by AnykeyNL)

   

   I took a look at the code that I started with and... it is kinda horrible.

   https://github.com/AnykeyNL/Quincy/blob/master/coordcalc.py#...

   There is a loop in a loop that goes through all the possible values of x and y to find the correct ones. No wonder it's so slow!

   The scipy solver - inspired by the original article, I used https://docs.scipy.org/doc/scipy/reference/generated/scipy.o... - isn't much faster though (from reading the docs, it's just a smarter random search).

   I guess it's time to learn some linear algebra (again!) and create a custom algorithm.
