Thanks Bobby. I figured that would be the case that firmwares etc.. wouldnt match up. It powers up and all interfaces work on the keypad, motors work, carriage moves and will do test cuts native to the machine. The ONLY thing that wont work is the computer recognizing it and it looks like most everything is located on that 1 mainboard.Sign Warehouse has recommended complete replacement, so I suppose I will pitch that to the insurance company and see what comes back. Sign Warehouse has given me the supporting quotes and recommendations. Just not sure how homeowners policy will look at a specialized piece of equipment. I am almost sure that a mainboard will fix it though, and worried that they wouldnt question $700 as much as they will $4k. Maybe I am just worrying too much.
