How To Guide: X-Rod and Rack Replacement
Here are some simple steps to replaced a damaged X-Rod and Rack:
  1. 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. 2.
    While holding the slider and X Rack, gently pull apart from each other. Please be careful as to not bend the Z Rods, only a small gap is needed.
    ​
  3. 3.
    Rotate the slider so the pegs point upwards. The X Axis is now free from the sliders.
    ​
  4. 4.
    Take the print head and begin to slide it off the x-rack towards the end that is free to remove from rack. Set print head aside.
    ​
  5. 5.
    To remove the damaged rods, carefully wiggle and twist the side that is glued to break the glue bond without applying too much force that will break the pegs on the slider
    Note: Remember which side the x-rack is located for next steps of replacing rods
    ​
    ​
  6. 6.
    Replace the rods on the pegs in their correct locations with the print head installed.
  7. 7.
    With the extruder in the MIDDLE of the X-rods, rotate the rear X-rod to the tightest position. This will reduce the amount that the extruder wobbles. Note: Sometimes you will have a rod that does not get tighter as you rotate it. That is ok, just move onto the next step.
    ​
    ​
  8. 8.
    Push inwards on the sliders to make sure the rack is pressed into the sliders.
    ​
    ​
  9. 9.
    While still pushing the sliders together, push the rear X-rod all the way to the RIGHT side. This ensures that if the rod is short and there is a gap on one side, the gap is next to the LEFT slider.
    ​
    ​
  10. 10.
    Flip the printer over and lightly glue the rack and rod to the left slider from the bottom.
    ​
    ​
  11. 11.
    Once glue is set, you are ready to print again!
