    I'm likely blind but what is the best way to connect 2 motors for the X-axis drive?

    I've seen methods were a terminal block is used to split the signals out of one driver,.

    But I was wondering if there is another way where you can use the 4th motor driver to power the 2nd X-axis motor as a slave to the motor 1 position. As i have seen other boards that have a slave terminal block that runs in conjunction with the 1st X-axis.

    Also we are using NEMA 23 motors on this build so i was worried about the draw from 2 motors being split from one motor driver.

    you can set your 4th driver to act as a slave of another driver

    $1MA - MAp motor to axis
    Axes must be input as numbers, with X=0, Y=1, Z=2, A=3, B=4 and C=5. As you might expect, mapping motor 1 to X will cause X movement to drive motor 1. The example below is a way to run a dual-Y gantry such as a 4 motor Shapeoko setup. Movement in Y will drive both motor2 and motor4.

    $1ma=0 Maps motor 1 to the X axis
    $2ma=1 Maps motor 2 to the Y axis
    $3ma=2 Maps motor 3 to the Z axis
    $4ma=1 Maps motor 4 to the Y axis
