Plotters and drawing robots are entertaining assignments that enable you produce artwork with all the precision and perfection that laptop or computer numerical handle can supply. [TUENHIDIY] demonstrates that ably with the Multicolor DrawBot.
The establish relies on a very simple XY Cartesian design and style, applying a pair of NEMA 17 stepper motors. It’s crafted in the regular CoreXY vogue, running GRBL firmware on an Arduino Uno.
Where [TUENHIDIY] will get inventive is in the pen by itself. Alternatively than using a straightforward ballpoint or marker, instead, a retractable multicolor pen is applied instead. With the multicolor pen on board, [TUENHIDIY] notes the relevance of restrict switches in the structure. These allow the the ‘bot to make numerous passes, just about every time in a distinct colour, to develop up a multicolor picture. Without having the limit switches in area, it would be unattainable to line up every subsequent pass.
We’d really like to see the create taken even more with a servo-based system for switching colours immediately. As it is, though, [TUENHIDIY] has a capable plotter that can produce tidy multicolor artworks.
A person of the more curious apps of plotters of late are people utilized to send out faux handwritten letters as a result of the postal program. Video clip soon after the crack.
