Replacing Damaged Cables

In the event that a control cable to either the Y or C-axis motors, limit switches, home

sensors, or pneumatic hose is irreparably damaged, it will need to be replaced.

Replacing a cable is fairly simple, though time-consuming.

The cables and hoses that run through the black plastic “energy chain” or cable carriers

are organized as follows: (cable reference numbers shown in parentheses)

X-axis (large, horizontal – back of machine), cable carrier:

Y-axis Motor cable (203)

*Plus (+) Y axis limit switch (top)

*Minus (-) Y axis limit switch (bottom), and

*Y-axis home sensor (*shared cable, # 204)

X-axis C axis (cutting head) motor cable (205)

carrier C axis home sensor cable (206) Y-axis

Black pneumatic hose (head plunge) carrier

Clear pneumatic hose (head retract)

Y-axis (small, vertical – left of gantry) cable carrier: (above shown in bold)

*Located on back side of gantry beam in extrusion slot

To remove a cable or hose for replacement, the segmented cable carrier(s) must be

“unzipped” along their entire length. For this example, we will replace the C-axis motor

cable, as it involves one of the longest cable runs.

1) Turn off power to the machine normally. Remove the cover guard plate over the

cutting head by removing the three screws with a 1/8” Allen wrench.

2) Disconnect the C-motor

cable connector. Using a

small pair of cutting pliers,

carefully remove any

plastic cable “zip” ties

holding the cable to the L-

mounting bracket. Note:

Keep any cable ties that

you cut in position, so that

it will be easier to

remember their locations

when re-assembling the

new cable and ties.

Cut cable ties carefully!
