Installing the Y-Axis Drag Chain
1.
Unroll and lay out the wiring harness on the
baseframe, move the X-rail all the way to the
FRONT, and move the Z-Plus 8 to 10-inches from
the Y2-carriage as shown in
Figure 6-10.
Figure 6-10
THE WIRING HARNESS
The complete wiring harness consists of the Y-Axis drag chain, X-Axis drag chain, four stepper motor
extension cables, two proximity switches with cables, and one proximity switch extension cable. Th drag
chain organizes and protects all the cables needed to operate the machine. It distributes power, and
connects the controller unit (the brains), to all the moving parts (the muscles). Although one unit, we often
break it up into the Y-Axis drag chain and the X-Axis drag chain. Take a minute to familiarize yourself with all
of its components described below and shown in
Figure 6

Y-Axis Drag Chain
The Y-Axis drag chain rests on the Y1-rail and serves as the protective housing for all seven of the extension
cables. It has 44 chain links with its tail being next to the controller unit and head on the Y1-carriage.
X-Axis Drag Chain
The X-Axis drag chain rests on the X-rail and serves as the protective housing for only four of the cables, the
X- and Z-extension cables, the X-Axis proximity switch, and the Z-Axis proximity switch extension. It has 54
chain links with its tail being next to the Y1-carriage and head on the Z-plus.
Stepper Motor Extension Cables
There are four stepper motors, the Y1-, Y2-, X- and Z-Axis stepper motors. The Y1- and Y2-motors work in
tandem to drive the gantry forward and backward. The X-motor moves it left and right. The Z-motor moves
it up and down. They are all connected to the controller unit by four gray 4-pin extension cables,
pre-installed in the wiring harness.
Proximity Switches and Cables
There are three inductive proximity switches, one each for the X-, Y-, and Z-Axis. They set the origin for the
machine and determine the limits of the work area. The X- and Y-switches, attached to the ends of their
black 3-pin extension cables, are labeled and routed through the drag chains. The Z-Axis switch comes
pre-installed on the front of the Z-Plus. It has a separate grey 3-pin extension cable that is routed through
the drag chains.
