Kelly54487 2 Posted March 8, 2015 Hi! I have a MH 871 and it worked fine yesterday, today however... as soon as I turned it on and started cutting letters it sounds like grinding noise is coming from the head. Blade holder goes up and down still but it's grinding and my setting are acting weird. I had to set the cut press to 000 Cust speed to 200 and raise my blade in order for it to cut. Cutting wording is where it grinds. Any help would be appreciated here. I have orders to fill and can't wait till Monday if at all possible! Thanks in Advance!

slice&dice 2,450 Posted March 8, 2015 In prior thread on this same issue, there was extensive troubleshooting dedicated to solving this issue on the MH unit. As it turned out, the motherboard was fried (maybe from excessive static?) and had to be replaced. In that thread, I couldn't believe that the motherboard would be the culprit, but I was proved wrong.
