Eo and E1 quesions on Rambo 1.4, attached is a jpeg of a switch used instead of included ends stops; may not matter? Items purchased from V1 engineering included the Rambo 1.4, 5 motors, mechanical-end-stops, full graphic lcd controller (it works fine) and connector accessories that came with the board. I have set the mpcnc up for dual end stop use. X,Y and Z, they operate fine via Repeteir host but not X2 or Y2, they free wheel, do not engage. End stops work as they should on X and Y and home the motors.
Wiring using signal, negative and positive for all end stops is correct on the board and light up when engaged. There is no end stop on Z. I’m not positive the firmware for dual end stops was included on the Rambo board? I don’t think this was a kit purchase even though the full graphic controller was part of the purchase? I’ ve not used arduino IDE much and before going through a learning curve to flash firmware downloaded from gift-hub, wondering if I’ve missed something. I checked wire via ohm meter, double checked connections on the board at motors and end stop switches.
