  • Topic: How to connect external microstep driver to mainboard
    You Reply: Hi pearl.chen!

    Thanks a lot for your reply. I think i need to clarify a little though.
    this is the driver i am using: http://www.jkongmotor.com/Product.asp?A ... Catalog=73
    The stepper motor connects directly to the driver so i dont/cant use the E slots. The driver and the motor are supplied externally with power with 24V DC.

    According to the schematics I would have used pins 9 (ground), 10 (direct), 11 (step) and 17 (engage) at E1 or E2. those are the signals i need for my external driver.

    I guess my question remains: If I connect my external driver with the motor hooked up to those pins .... Any chance of ruining the board?

    Thanks for your help
