On some machines, the X-axis ribbon cable may need to be replaced. This article intends to show how to do so.
Products Affected: Series 1 (2014 - Serial Numbers B01-B61, 1000-1080)
Skill Level: Easy
Time Required: 45-60 Minutes
Tools Required: 2mm Allen Key
1. Completely power off, disconnect and unplug your machine.
2. Move the tool head forward so that you can get at the offending X-ribbon cable.
3. Unscrew the bolts that hold the ribbon cable spine in place. Note that these screws also hold the breakout boards mounted, so don't lose them!
4. You will find that the extruder and Y-motor wires will be wrapped around the ribbon cable spine's hooks to keep them in place. Undo them as needed - just remember to put them back into place!
4. Disconnect the thinner IDC (Insulation Displacement Cable - through which almost all signals travel.) Those who have ever upgraded RAM on their computers will find this step familiar - simply pull the two tabs of the connector apart and the cable should come right out.
5. Disconnect the thicker 6-pin power transmission cable. To do this, locate the tab on the middle of the connector. You might need to press hard to get the tab to come off.
6. You should now be able to remove the ribbon cable. Next is to replace it with the new ribbon cable by working backwards. MAKE SURE YOU ARE CONNECTING THE CABLE IN THE CORRECT ORIENTATION. You should not need to twist any cables or cut any of the insulation in order to achieve the correct connection. See the photos in this article for the correct orientation of the X-axis ribbon cable.
Addendum: Reinstalling the ribbon cable spine bolts to the PCBs and the sheet metal is a bit tricky. There are a variety of ways to achieve this. I personally used a tweezers to hold in place the nylon nut while attaching the spine with the bolt already in place.
