We see loads of easy pen plotter tasks round right here, and whereas we respect them every person, most of them are just a little on the gradual facet. That’s OK — a glacial tempo is typically all that’s wanted, so long as it will get the job carried out. However there’s nothing improper with placing the pedal to the metallic, so to talk. And that’s precisely what this super-fast Arduino-based plotter is all about.
Because the story goes, [IV Projects] felt the necessity for velocity after constructing an earlier pen plotter undertaking that labored, however did not excite. With the extra objective of protecting the plotter straightforward to construct with low cost components, the design facilities on a “grit curler drive” for the Y-axis — the one that truly strikes the paper forwards and backwards. And transfer it does, utilizing Dremel software sanding drums on a light-weight shaft to maximise acceleration. The truth is, all of the transferring components are saved as light-weight as doable, and the outcomes actually present — the three steppers actually sing when this plotter is in motion.
There are some actually intelligent particulars in [IV Projects]’ design. We notably like the best way the pen carry mechanism works, and the shock look of a clothespin spring as a belt tensioner was an actual deal with. Judging by the pile of rejected prototype components, it took fairly a bit of labor to get this design proper. If you happen to’d wish to construct your individual, STLs are available for the printed components.
If you happen to’re serious about what the opposite finish of the velocity scale appears like, try this bare-minimum pen plotter.
