M280 P0 S140 ← Only 5V Logic mode ( Do not activate 5V logic on 3.3V logic system without 3.3V logic conversion) Learn all you need to know about BLTouch auto bed leveling sensors: what they are, how they work, and setup guide instructions. Likewise, the PWR-DET (Power Out Detection) connection on the BTT SKR Mini E3 V3 follows the same wiring orientation as the Filament Runout Sensor. Specifically, the lefthand pin is the Signal wire, the middle is Ground, and the right is Voltage. Signal (White) At Inductive Proximity Sensors, to calculate the sensing distance for other application conditions the following parameters, which affect the sensing distance, must be taken into account. (For example : Variations in ambient temperature(Kθ), Different types of object material(Km), Size of the object to be detected(Kd), Variation of supply voltage(Kt)) My leveling BLTouch is 37mm to the right of the nozzle, and 2mm behind it, so I would put the following settings. You must measure these values ​​to enter on your printer (do not use mine).

The BLTouch wiring connects to the Ender 3 mainboard by splicing into the Z Endstop connector. This connector is labeled with a small yellow label that reads “Z”. Every once in a while, a BLTouch probe will go into alarm mode. When it does, it will continuously flash the red LED. Furthermore, the reset command resolves most issues without the need to restart the mainboard. M280 P0 S160 ; Filament initial heights – Probes

Because maybe you can’t read the default Chinese Ender 3 menu. Which is the correct firmware for Ender 3 V2? Wide application： Compatible with ABS, PLA, glass, metal, plastic, and all materials.Support more filaments and apply to every control board of 3D printer

Follow the included instructions to use the the progisp software to upload the firmware to the mainboard. Carefully remove the control box enough to access the motherboard, paying special attention to the fan.

BTT SKR Mini E3 Setup Complete

To choose an option, uncomment it by removing the slashes. Note that only one option can be left uncommented. Your code should look something like this: Even though paying attention to these two factors for configuring the start G-code will ensure that your BLTouch will run and automatically level the bed before each print, the code won’t be fully optimized, which we will cover next. How to Optimize the BLTouch Start G-Code? The second vital point to discuss is the necessity of executing the G28 command before initiating the bed leveling process.
