@JAZZCNC Thanks for your quick reply. I'm tempted to just bite the bullet and open the control unit up have a look and try to repair myself. There seems to be no way of contacting the supplier, I could return to Amazon but from what I have been reading I'm considering sticking with it and improving the system.

Seen lots of articles about interference etc. from VFD and poorly cabled internal control units with shielded cables internally. Given it is a VFD motor what would be my options to replace the controller. I don't even mind managing the spindle speed manually but even that seems impossible without MACH 3.
