I meant to post this a while back… When I first got started using my newly assembled X-Carve, I thought I’d try producing some of the parts for my computer case project (see here: First project - I carved a computer! - Projects - Inventables Community Forum). While creating the front case part (in particular, cutting the front panel cut-out), for some unknown reason, the machine plunged the 1/8" cutter almost all the way into the 3/4" thick pine work piece and continued with the cutting. I don’t remember if I just allowed the X-Carve to continue out of total amazement or not, but as soon as it had finished cutting out this cut-out, I aborted the operation. The result was the 1" x 4" piece of pine as seen in the attached photo. What amazed me was that the X-Carve had made this cut-out practically in a single pass. Here, I say “practically” only because the Z-axis hadn’t dropped to full 3/4" depth–it was short by about 1/16". The cut settings that I was using at the time are those in Easel for “Soft Maple”. I don’t believe that I changed anything at all. So, by pure accident, I found that the X-Carve can actually cut 3/4" thick (“one-by”) lumber in ONE pass! Is this amazing or am I the only one who hadn’t realized that this was possible? Of course I wouldn’t advise doing this in normal operation but it’s kind of cool to know that the machine can do it. 
7/8" deep? OMG! When it happened to me I couldn’t believe that the bit didn’t fly off in little pieces. Yeah, the chatter indicated that my X-Carve had its hands full indeed. I still have no idea what caused the plunge because later running of the same g-code worked fine…
