How to Replace a Replicator 2X XYZ Endstop Cable
These are instructions for replacing the XYZ endstop cable on the Replicator 2X. They will
require the use of the 2.5mm hex wrench that came with your bot, several zip ties, and a
wirecutter or strong pair of scissors.
Note:
Your new endstop cable should ship with the jumper cable already attached. If they are
not already connected, simply attach the larger end of the jumper cable to the Xaxis motor
cable. You will also receive a jumper cable for the XYZ motor cable, which you should also
attach.
Before you start, do the following:
• Unload and remove any filament.
• Turn off the Replicator 2X.
• Remove the filament guide tube and spool holder.
• Unplug power and USB cables.
• Remove the right side panel of the Replicator 2X.
The XYZ endstop cable connects to the Mightyboard with a single connector, but from there
branches off in three directions, one section going to each of the three endstops.
1. Disconnect the cable from all three endstops, as well as the motor cable from the
Xaxis motor
.
Unplug the black plastic cable connector from each endstop. The Yaxis endstop is located at
the upper back left corner of the Replicator 2X’s interior. The Zaxis endstop is located behind
the top section of the threaded Zaxis rod. The Xaxis endstop is located on top of the Xaxis
motor, at the right side of the gantry. Also unplug the motor cable from the Xaxis motor.
2. Detach the Xaxis section of the endstop and motor cables from the gantry.
The Xaxis sections of the endstop and motor cables route through a hole and into a slot on the
side of the gantry. Pull the cable connectors free of the hole. Then pry the metal dowel out of
the slot at the side of the gantry and set it aside. Slide the endstop and motor cables out of the
slot.
3. Detach all three endstop cable sections from their cable clips.
There are two kinds of clips holding these cable sections to the interior of the Replicator 2X: a
curved metal flap and a plastic piece with a hole for a zip tie. Remove the cables from the zip tie
clip using a strong scissor or wirecutter to clip the zip tie, being very careful not to damage the
