Got the first servo motor today and since it is not a geared motor it is very easy to turn by hand. Looks like my possible plan of having to put in some type of clutch mechanism to disengage the motor when operating the machine manually won't be needed. I will see once the motor is driving through a reducing pulley if that is still the case.
Should have the power supply tomorrow. Might be a few days before I have time to hook it up and run through Mach since I have a bunch of work projects to finish.
