A low-cost and easy to build 3-Axis motion plattform is presented. It can achieve step sizes down to 50nm while supporting arbitrary acceleration limited motion paths in a working volume of 23x23x23mm³. The simple G-Coder interface allows easy control from printer-hosts or custom software. The device can be used in applications, like automated microscopy, optical alignment or maskless lithography. ✅ Project on Github: 🠲 I am looking for a better project name?
