Talk:Stepper Expander
I have purchased this expander x2 and am looking to upgrade my anet a8 to 3 colors. I have everything hooked up, the 5v light is even on, only unsure of one thing, and with me being realatively new I dont want to blow my board. as far as the vmot and grnd, where on the ramps board should they be connected to? 12v-aux? and any help with defining pins would be righteous.
- There is no 12V source on the RAMPS board, suitable to power extra stepper drivers. The RAMPS board only has digital and analog pins on the Aux ports.
- The Expander needs its own 12V wires, directly from the power supply.
- and only the control signals go from the RAMPS Aux ports, to the control pins on the expander board.
