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.
