# How To Guide: Cutting X Rack to length

**Problem: Y Stalling/ Skipping**

In the factory we cut the ends of the X Rack, which is the **toothed rod** the print head moves on. You may be experiencing Y Stalling/ Skipping if the ends of your X Rack are not cut. Here are some simple steps to fix the problem:

1. One side of the X Rods will be glued to the sliders, one side will not. \
   **Hold** the slider in one hand, and the X Rack in the other.

2. While holding the slider and X Rack, *gently* **pull** apart from each other. \
   \&#xNAN;*Please **be careful** as to not bend the Z Rods, only a **small gap** is needed*.

3.  **Rotate** the slider so the pegs point upwards. The X Axis is now free from the sliders.

4. **Trim** piece of plastic sticking out from X Rack. \
