TerraPen — Open Source A2 CoreXY Pen Plotters

Blending Art and Technology

a tool for computational artists that is easy to set up and use out of the box

Example

terraPen’s mission is to make large format artwork easy to produce from a reliable quality product, supported through an open source community.

the terraPen A2X

Our current-generation A2 pen plotter: a fast, precise CoreXY machine, hand-built to order and open source down to the design files and firmware.

An A2 plotter designed and built in the UK by pen plotter artists, for pen plotter artists. Rigid SLS-printed nylon parts give smoother motion and easier servicing, a stepper-driven pen lift takes pens up to 16mm, and FluidNC firmware lets you run it from any browser, from our free terraForge app, or from terraDial at the bench.

We've listened and worked closely with the community to build a suite of tools that develop your creative practice, straight out of the box.
