How can I print to my FLSUN QQ over WIFI
Assuming you use Ultimaker Cura to slice, there is a MKS plugin that allows connecting to the MKS WiFi module that comes with the QQ. Just follow these steps:

Install the MKS WiFi Plugin


Open Cura
Click "Marketplace" in top right
Select "Plugins"
Scroll down to find the "MKS WiFi Plugin"
Click on the plugin.
Click "Install"
Restart Cura (quit and reopen)


Configure WiFi 


Turn on your QQ
Tap Settings
Tap WiFi
Enable WiFi
Note the IP address and network name
Connect your computer to the printers network
Open your browser
type the IP address of your printer into the address bar
hit enter
Scroll down to "WIFI Configuration"
Select STA
Enter your home network SSID into the field labeled "WIFI"
Enter the password into the field labeled "KEY"
Click configure and reboot


Setup your printer in Cura


Open Cura
Open settings > Printer > Manage Printers...
Click "MKS Wifi"
Click "Add"
Enter the new IP address of your printer (can be found by opening WiFi settings on the printer)
Click Ok
7, Click connect.


Now you should be connected to your printer. After slicing you should have the option to "Print over FLSUN..." In the Monitor interface you should have some other options such as sending commands to the printer, and printing any files already on the SD card, as well as uploading gcode files to the SD card. 

Happy Printing
