It’s a long story, I originally owner a 24 X 36 Axiom which was about 6 years old. About May of 2021 I was thinking it would be nice to have a tool changer. Looked around and settled on a Step Craft Q404 and ordered one. Did some research and looked at YouTube for information. Call one person with a 4 X8 and got a good recommendation. Big mistake. Not very happy with it. One problem after another.
I’m back on an AR 16 and it’s great. As I expected it works as advertised. I can live with the tool change!
