I talked with tech support and they pretty much narrowed it down to a Z chip issue with my MH871. I did the 9V battery test and the arm did "jump" so it sounds like a Z chip will do the trick. I will let you know how it goes once I receive it. Anyone replace a Z chip and it still didn't work?

Just had my MH 871 do the exact same thing yesterday. It basically stopped cutting in the middle of the job, after a couple power cycles and even rebooting the compter (just for good measure) the blade still would not lift. I put a ticket in with US Cutter but if its just a chip that would be great. Anyone know how to install the chip? Does it come with instructions if you buy it from US cutter?
