Step 1 : Test the cable
Turn the machine on its left (your left when facing the machine) side and remove the base plate that protects the motherboard.
Remove the right side panel off your machine (6 large cap screws hold it in place) for easier access to the X axis cable
Now unclip the X axis endstop cable and connect the new cable (the longest ribbon cable length) by just threading it through around the
outside of the machine and in the right side window
Unclip the Y and connect the new one, again running straight through the right side window.
Lastly do the same for the Z Endstop, again just through the window.
Now connect the new cable to the motherboard. It is the only connector of its size on the motherboard (see fig 1.1)
Gently turn your machine upright, be careful not to squash any cables as you have a few dangling about now.
Plug in and turn on the machine. If you press each of the endstops a red light should light up on the endstop board (see picture 1.3).
Now test the new cable by telling it to home, after having slid the extruder to the front left.
All good ? Yes? Then tidy up, otherwise contact us.
Step 2 : Tidy up
Start at the x motor.
Start by disconnecting the old cable, working backwards from the stepper motor. Be VERY careful when cutting the small zip tie
that holds the motor cable to the endstop cable and unclipping the cable from the cable clips on the chassis. You will find the cable enters
upwards from the motherboard into the machine body through a small triangle hole in the base, push it through into the motherboard area under
the machine and thread back up the new cable.
Plug the cable into the stepper motor and re-trace the cable path, popping the cables back in the cable clips on the chassis, push
excess cable back down to the underside of the machine.
Do the same for the Y and Z axis endstop clips.
Turn the machine upright and test again.
Step 3 : return the damaged cable
We ask that damaged cables are returned to us in an envelop so that we can test them and try and work out why they broke.
They can be sent to :
