Introduction

If you own a FLSUN QQ and the original bed is worn out, or if you simply want to upgrade for easier print removal, this guide will walk you through the process.

Recommended: If you have not upgraded to the leveling switch I recommend the FLSUN QQ Leveling Sensor Replacement guide first so that you can more easily level after installing the new print surface.

What you need

Step 1

              Heat the bed to 70º F
  • Power up printer
  • Tap Tools
  • Tap Heat
  • Tap Extrude 1 to switch to Bed
  • Tap + till the bed temp is set to 70º

Step 2

              Wait for the bed to reach temp
  • Heating the bed will melt the adhesive and make removing the old print surface much easier

Step 3

              Peel up Old Print Bed
  • Use the putty knife to start peeling up the old bed.
  • Once you get the edge started you should be able to peel the rest by hand.

Step 4

              Remove auto level wire
  • One side of the bed will have a wire taped in with the conductive sticker.
  • If you have upgraded to the leveling switch you can cut this wire.
  • If not, you could carefully peel the wire off of the conductive sticker to save it for later…
  • Without the leveling switch there are various techniques to do conductive leveling.
  • aluminum foil stuck to top of bed and connected to leveling wire
  • homemade leveling switch
  • etc.

Step 6

              Apply the Magnetic Sticker
  • Leave the steel plate and magnetic sticker together.
  • Remove the backing from the magnetic sticker.
  • Be sure to align the plate exactly how you want it. Once the sticker is applied it is very difficult to remove and repositioning is not recommended.
  • Carefully apply the sticker and plate from one edge to the other.
