Note: Using a slicer other than Creality Print for slicing and printing will not allow you to utilize the full capabilities of the Ender-3 V3. This includes, but is not limited to, features that enhance print quality such as "Activating the cooling fan only in specific areas (overhangs and bridging sections)" and "Automatic temperature control" (adjusting the extrusion temperature based on flow rate).
1.Open Orca Slicer, import configurations
2.Remember the IP in WIFI in the printer's screen menu.
3.Open Orca Slicer, select the imported printer profile "Ender-3 V3", click on the WIFI icon next to it, for "Host Type" select "Octo/Klipper", for "Host Name" enter "xx.xx.xx.xx:4408/", where "xx.xx.xx.xx" is your printer IP address; in the "Device User Interface" enter the same content as the host name, click confirm to complete the setup.
4.Now, in LAN status, you can use OrcaSlicer to directly send the sliced files to Ender-3 V3 for printing!
