How to setup BL Touch on Ender 3 PRO - 10 minute install - Tresbro
0BL Touch automatic bed levelling sensor for the Ender 3 Pro is a fast and easy setup. The sensor provided in the link below will work on both the V1 and V2 Creality boards as well as the SKR / SKR Mini series boards.
PAY CLOSE ATTENTION TO THE PINOUT ON YOUR BOARD AS YOU MAY NEED TO SWAP WIRES IN THE HARNESS! - This is quick and easy as they pop right out, so switching the 5V cable to the middle pin was switched in about 30 seconds.
The whole install took about 10 minutes, and updating the firmware on my main board was really simple. After setting my offset I was printing perfect layers every single time I ran a job.
If you are using an SKR board, you will need to plug into the SERVO port and then you can choose to use either the Z-Endstop or the PROBE port.
After some testing, I decided to use the Z-Endstop instead of the Probe. If you would like to use my firmware, please plug into the Z-Endstop and SERVO ports. THIS IS VERY IMPORTANT! (DOWNLOAD LINK BELOW)
