Plotter

In November 2013 I started designing a big 2D plotter for Tiago Batista (Assistente Convidado, Artes Visuais, Faculdade de Ciências Humanas e Sociais,Universidade do Algarve).
I started with an H-bot with wheels running on the aluminum profiles (lowest picture) but it gave me a lot of trouble with the rigidity of the x-rails (see bad circles).
At the time it wasn’t possible to boy v-slot profiles longer than 1m.
In the end I switched to “CoreXY” and replaced the wheels with some low friction Nylon.
