The 1100M wiring diagram shows four wires feeding the Accessory Input #2. They are 5VDC+, 12VDC+, Input and COM (photo attached). I have the ETS red wire connected to the Accessory plug 12VDC pin, the ETS green wire connected to the 5VDC pin, the ETS Black wire connected to the COM pin, and the ETS yellow wire connected to the Input pin.
I then selected the Passive Tool Setter for Accessory Input 2 and the green light is lit on the ETS Setup screen. When I click on the ETS Spindle Ref button the Z axis moves down but doesn't stop when the ETS plunger is pressed. I've obviously wired it wrong. Can someone tell me how to wire it correctly? Any help is appreciated.
