By swapping them, you move cable or connector and the electrical connection is (temporarily ) established.
The stepper motor always rattles when one of the phases is missing or it's intermittent.
Power supply (low) voltage is another possibility, however unlikely in my opinion, given that motors actually work (when swapped).

Thanks BPO and Bojan.
I've received the NEMA 17 motors I ordered as replacements (from automationdirect.com.au - STP-MTR-17048) but of course now have the amusing task of interpreting the wiring and preparing suitable connectors for the EQ6 control board. The new motors are 4-wire 1.8 degree (I think they are bipolar parallel type but am not sure about the proper description) and they come with a plug that does not suit the EQ6 control board and will require either a new plug or some form of adapter. But either way, I'm wondering if anyone knows which are the A, A+, B and B+ wires on the standard EQ6 motors so I can match them up with the new motors. (The product description does not use the + symbol but instead has a line above the letter - like a minus sign on top of the A or B).
Peter.
