Introduction


This guide will walk you through the process of disassembling the print head and replacing the X-axis limit switch. 


Important Notes

  1. Strong Yellow Glue: The connector on the X-axis limit switch is secured with a strong yellow glue. You may need to carefully cut or gently wiggle the connectors to release them. Avoid forcing the connector, as this could damage both the X-axis limit switch and the cable.

Step 4. Unplugging the X-Axis Limit Switch Cable


The X-Axis Limit Switch can be located on the left side off the Toolhead.


Important: 

The connector on the X-Axis Limit Switch is secured with strong yellow glue. Be sure to carefully cut or score through the glue before proceeding.

Use a flathead screwdriver to gently score or cut the glue. Once that’s done, you'll need to compress a latch to release the cable. I recommend using tweezers for better precision and ease. For reference, please see the photos below:

When installing the new board, you'll notice a notch that aligns with the hole on the X-Axis Limit Switch. This alignment is clearly marked in the photo below for your reference.


Once the switch is aligned, use your 2mm Hex driver to tighten the screw and securely fasten the X-Axis Limit Switch in place.
