Turning off DeWalt 611 stops Easel

X-carve 1000x1000 DeWalt611. Ok my DeWalt is running off of 1 circuit. My X-carve controller is running on a UPS separate circuit. My Computer is on a third ups protected circuit. If I am in the middle of a carve, pause my carve, turn off my router, Easel comes back to How was the carve Great?. Well the carve never completed…So if everything is on a separate circuit, when i turn my router off why does Easel assume I’m done?
Any ideas or thoughts or knowledge about this problem out there?
