What I wanted to ask, is how much rs is better than r? I'm just starting to make my first cuts with R-CNC and I think is it necessary to plan for an upgrade as fast as possible? Is it worth taking another few months (I have not a lot of free time:)) to make second machine or will this time be better spent making some cuts and learning more how to use my first machine?
PS. By the way, it would be cool to somehow incorporate the possibility to connect a z-probe. Do you have any plans for this? Does your new shield support it?
