Connections:

Step 1:

Connect all stepper motors to the X, Y, (if using a gantry style machine Y2) and Z. The 6 pin connectors

are labelled below. Looking at the face of the box the connections are, from left to right:

Accessories :

Black/ White = Z probe

10V

X Axis:

Black/White = X axis limit switch

Y Axis:

Black/White = Y axis limit switch

YNL: (this is only needed on gantry style machines with two Y motors)

YNL stands for Y axis no limit, the black and white wires are not present on this axis.

Yellow/Blue = 1A 1B stepper motor pair

Z Axis:

Black/White = Z axis limit switch

NOTE: If your machine is a kit from us this will directly plug (color to color) into the stepper motors and limit

switches.

NOTE: All limit switches are filtered and should be used in the NO (Normally Open) position.

Yellow/Blue = (+/-) PWM

Yellow/Blue = 1A 1B stepper motor pair
