My CNC v3.2.1 that came to life during the Hackaday Prize 2016 works fine for me, however there are still improvements in my mind. To give the development of this machine a new push I have added a new project for this year's Hackaday Prize:

https://hackaday.io/project/85486-basic-diy-cam-2018

Please follow that project to stay up to day about changes of this machine series.

I will declare this project being finished even if it isn't, but I must create a new project to participate in the 2018 Hackaday Prize with the ideas I have in mind for my CNC series.
