Well, one good day with my machine up and running before I put it temporarily out of commission with a stupid mistake. I cut a few things successfully and then stupidly forgot to check the toolpath simulation before starting up a surfacing run on a project board. Sent my 1" wide bit straight into a clamp right away, before I could even react… I shattered the clamp, bent the m5 bolt from it, chipped up the router bit pretty badly. But worst of all, I knocked the Z-carriage off its rail on the bottom two v-wheels. The top two were still in place, but the whole thing was leaning forward. Didn’t realize til I went to home it and it wouldn’t move upwards. Got in there and found that the bottom left v-wheel was wrecked. 
Got it out and examined the pieces; it looks like the bolt, nut and rest of the carriage are all fine, it’s just the v-wheel that took the hit, so a decently cheap fix and a good learning experience.
But I wanted a second opinion; is there anything else I should consider replacing at the same time? Anything else I should carefully examine for issues? I would hate to replace it and realize I didn’t think to inspect something else that is broken. Not to mention that shipping on a single v-wheel alone costs more than the part itself… I’d love to skip on ahead and upgrade to the cnc4newbies slider right now instead, but it’s a little outside of the budget, sadly.
On the plus side, thanks to this forum and all the reading I was able to do between black Friday and when I finally got my machine assembled, my first couple projects went really smoothly! I was using g28, a bump stop, a v-bit and 2 stage carving right off the bat! So thanks, guys!
