CNC Electronics (Custom CNC Part 3)

If you are just joining us, take a look at part 1 and 2 at: Custom Built CNC, an Introduction https://replicantfx.com/cncpart1/ Building the Structure, Folding CNC https://replicantfx.com/cncpart2/ Version 1 (G251 + parallel breakout board) It took me a long time in life to realize I should do it right the first time, but lets not be too tough on me. […]

Folding CNC (Custom Build CNC – Part 2)

Finally I have gotten to talking about version 3 of the CNC router. (Want to see where I started: Part 1)I learned my lessons, pulled on my big person pants and finally did it right. Doing it right started with getting the base table right. For years I had been designing bases out of wood because welding and working with […]

Custom Built CNC – Part 1

Welcome everyone. To cover my past and current Computer Numeric Control (CNC) build will take a few posts. I will be breaking up the documentation and discussion into sizeable chunks. I will introduce the first few builds but avoid the deep details. The final build will be full of details as it is built using all of my lessons learned […]
