Have a Implotex compressor and a omio 3040 that dont seem to like each other

This happens pretty much every job. Sometimes it will cut out, sometimes not. The compressor is plugged into a different wall socket (in my small utility room).

When the compressor kicks in or off I get a ncusb error on mach3 and the spindle stops.

Anyone had this issue? Ive been thinking about upgrading to a UC300ETH, not sure if it will fix the issue though
