Since I started assembling my cnc about 2 years ago, I had intended to use dual computer monitors. Recently, while digging thru some packing crates, I found a spare monitor. I immediately ordered mounting brackets from Amazon and when they arrived I added them to my "to do pile". It rained all morning so I decided it would be a good time to get the 2nd monitor mounted. I've made a lot of changes to my machine since starting and I hope this is the last one for a while! Rotary axis?
