Replaced the motherboard and I am back up and running. Thanks guys!

Yea, that is the only one I see also. I will contact USC. Thanks!

I took off the end cap and located the motherboard. Mine is stamped GOLDCUT 2011A. The picture of the one on the site says GOLDCUT 2010A. http://www.uscutter.com/MH-Series-Refine-Motherboard-MK2 They look identical and chances are, it will work. I just want to double check before ordering. Thanks again guys, your help is amazing!

Thanks slice&dice and Primal. I will upload to youtube next time. Looks like the motherboard is 80 bucks, not bad. Will this solve the earthquake issue? I only ask, cause that seems like a mechanical problem. But I could be wrong.

Thank's for the quick response Dakotagrafx. I checked everything and the carriage is on track and the rollers are tight. Something I forgot to mention, the machine turned off and on when someone touched it. I assume static shock, which is why I am thinking a bad motor. I am thinking the same, that it's not the board because it still connects and tries to cut. Here's a vid of it in action. Again, thanks for the help.

Hello, I purchased a second hand MH721-mk 2 a few years ago, and it has been performing great until recently. Attached is the current result of a few cuts. The one on top is a cross and the one on the bottom is the word "test". I have tried both the usb and serial connections with the same results. And I am using signblazer to send jobs. I have a feeling either a motor or the control board needs to be replaced. If it's both, I don't think it would be worth it to fix and would probably just replace it. But if it's just one part, I think it would be worth it to keep. Any help is greatly appreciated.
