The selection depends whether you have a BLTouch in combination with that mainboard or not. We’re going to talk about the BLTouch installation in another video. Another thing you need to know is, which mainboard version your printer has. Actually, I did this two times because Creality released new firmware versions during the test period.<\/p>\n

\"how<\/p>\n

When a new print starts, you may notice that it does a routine in which it goes to its home position before initiating the entire job. After the said routine, the printer only follows the instructions given by the G-Code and actually does not remember any previous notion of the initial position. It just assumes that it correctly homed and that all the following movements were correctly executed. Before getting started, make sure you have Arduino IDE installed on your computer since it will be required in order to compile the firmware.<\/p>\n

If the JRx (single) hot end has been installed, the LCD screen should read \u201cAirwolf HDx Ready\u201d. If the JR2x hot end has been installed, the LCD should read \u201cAirwolf HD2x Ready\u201d. Go into the VIKI and select \u201cPreheat PLA\u201d to test the newly installed hot end. Upgrading your Creality Ender 3 or Ender 3 Pro with a BLTouch probe for auto bed leveling will ensure your prints have perfect first layers every time and greatly reduce issues with bed adhesion. Additionally, the BLTouch probe allows better tolerances for slightly warped print beds by measuring and compensating for any inconsistencies.<\/p>\n
