Brand new CX with 2.004- used daily, no problems at all until now. Dust collection and vacuumed after each use- no fouled belts, truck is free to move in all axes. During bit loading the bit finds home (below surface level) and touches the swing-out touchplate (above surface level). The only issue is when the bit (1/16"carving, BTW) is supposed to touch the wood surface it comes SO close- but doesn't touch. All other automated measurements are otherwise fine i.e. length, width, etc. Double-checked the board settings for the piece in Designer and it's correct. When the fault occurs, there is no error message, it just re-directs me to load the bit again. Tried ABORT-and-start-over, tried power OFF and restart, etc... everything except re-format the card, which doesn't seem applicable here. I'm very experienced in trouble shooting my old Rev.A Compucarve, so I'm no newbie. Any ideas?
