I really like grbl firmware, but it can only handle 3 axes CNCs. This works great for most hobby CNCs. I am always on the lookout for a different solution. I looked at several and the grbl-ESP32 seemed to be the best fit for BobsCNC. I have a prototype board and a slightly modified off the shelf rotating axis I am trying out.

I made a video showing my progress.

About BobsCNC

BobsCNC is what happens when two old friends, one with a background in mechanical engineering and a long history of building CNC machines and the other with a career in sales and marketing, join forces along with their wives and family. What began in a garage shop in 2015 rapidly grew into a thriving enterprise that is revolutionizing the way CNC machines are made.
