Introduction

Note: This guide is for the FLSUN QQ not the newer QQ-S

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.

FYSETC Flexible Build System

Step 1

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

Heating the bed will melt the adhesive and make removing the old print surface much easier

Step 3

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

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 5

Power down the printer
Use mineral spirits, gloves, and cotton balls to clean the bed

Step 6

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.
