‘Wolverine’ CNC Gantry Robot

Multifunctional Powerhouse – Part 2: electronics and software

‘Wolverine’ CNC Gantry Robot
In part 1 of this series (ElektorLabs March & April 2019 [1]) we described the mechanical construction of our CNC gantry robot. Now it’s time for the control electronics and the software. We also present some simple CNC projects to help you get started with the gantry robot and learn about the various software packages you can use together with our machine to create your own products.
