Machine looks good !! Mine is working awesome
I know what you're saying about learning all this stuff. It can get overwhelming at times. The biggest problem I think is that we're playing with equipment that's not really designed for the masses, and the instructions that come with them are not the best.
You made the right choice by using the CandCNC controls, because IMHO it's the best out there. Tom is a very smart guy, but because of this, his instructions are very difficult to understand for the newcomers like us. A lot of the information he tries to tell us leaves us scratching our heads because we don't understand it inside and out like he does. In a few weeks, it will all make sense !!
I'm no expert at this either, but if there's something you're not sure about, ask me and I may be able to help.
Good Luck !
