What is a Zarplotter?
The Zarplotter is a four motor drawing robot originally created (to our knowledge) By Randy Szarzynski et al in California. They sell a fully finished machine which you can purchase at https://www.zarplotter.com/.
This machine is in the early days of testing, and already runs 30% faster than a Makelangelo 5 vertical drawing robot. It has a quick-change pen adapter to work with many styles of markers or pens, and can be physically expanded to larger drawings than the ~60x60cm (A2) drawings you see here:
Why make a Zarplotter?
We were challenged to build a new Skycam/spider cam robot, which has four motors at the top of a box. Making a Zarplotter was a natural intermediate testing step, having nearly the same shape without the huge vertical Z movement.
Because it’s frikkin’ cool, ok? 🙂
This item includes the four corner mounts, the center pen holder, the belts, the electronics, the LCD, and the power supply. You will have to supply the flat drawing surface yourself. At this time no electronics enclosure is included.
By purchasing this robot you support us in our research & development of creating open source robots. Thank you!
This item is for a mostly-assembled kit. ROBO-0048 is the bill of materials list for those who want to DIY the entire thing themselves.
How big can I make a Zarplotter?
We tested on a machine 60x60cm (~24″x24″). Larger is doable in the software and the hardware, though you might need longer timing belt, motor extension cables, and servo extension cables.
Please let us know if you plan to go larger and we can suggest what to add to your order.
Will I need anything else?
You will need the open source 3D printable Zarplotter models.
You will need the open source makelangelo firmware code that lives in the brain of the robot.
You will want the open source makelangelo software Java app that makes running the robot easy peasy lemon squeezy.
