    Hey everyone! I just built a makelangelo custom with an arduino mega board and a ramps 1.4.. everything seem to be working great.. except for seemingly one thing.. when using the manual drive controls.. when I press -10 left.. it goes up, when I press 10 right, it moves down.. when I press -10 down it moves right.. and when I press 10 up it moves left…

    I tried switching some of the stepper wires around but It just seemed to freeze the motors up..

    I tried reversing the orientation of my stepper drivers, but I think that just fried them..

    not sure what Im doing wrong..

    HeWP!

    I hope you reversed them with the power OFF. (dis)connecting motor or adjusting the voltage dial on an A4988 driver with power on WILL kill the driver.

    Second thing to check is that you have setup your machine limits. New machines require a factory reset. In the latest firmware that’s an M502 command.
