Well, it’s been a good long while since I gave this thread any thought and today I figured I would just throw this block at my x-carve with a yonico carbide 1\4 inch bit since I figured, eh, my machine is tough, might as well try it! And to my surprise, it went perfectly! I intended to set the DOC fairly conservatively, and didn’t realize it was cutting so deep, but to my chagrin the machine didn’t even flinch cutting somewere around 1\8 inch DOC. AMAZING!
