Multicolor Drawbot Highlights Importance Of Limit Switches


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.
