Creality Ender-3: Installing a Clean Marlin and Configuring BLTouch
In the first part of this video, I'll show you how to flash a bootloader to the Creality Ender-3 3D printer using a USBASP programmer or Arduino UNO, and install a clean Marlin firmware from the official website.
In the second part of the video (6:41), I'll show you how to install and configure the BLTouch autocalibration sensor on the Ender-3. I'll use the original BLTouch as an example. I can't make any promises about the performance of the clones yet. For comparison, I've already ordered one of the cheapest clones.
I apologize in advance for the connection diagrams; I don't know how to draw them. I did the best I could.
I apologize for any omissions in the video:
The servo cable for extending the BLTouch wires needs to be quite long.
The Bilinear method by default tries 9 points instead of 6.
UPDATE: When editing the startup Gcode. If you use a different temperature for the first layer than for the subsequent layers, it's better to use
{material_print_temperature_layer_0} instead of {material_print_temperature_layer} in the startup gcode.
UPD_2: If you're flashing the bootloader using an Arduino with a CH340G chip and encountering issues, use Arduino IDE version 1.6.9.
You can use the driver from here: https://all-arduino.ru/drajver-ch340g....
On the Arduino Nano, the ICSP port is reversed, meaning the GND and 5V pins are on the USB port side.
UPD_3: The issue of the 3DTouch (Bltouch clone) dropping out when navigating the printer menu can be completely resolved with firmware. In the pins_SANGUINOLOLU_11.h file, find and comment out (put // at the beginning of the line) the line
#define BEEPER_PIN 27
There are two such lines; you can comment out both, but the first one is sufficient.
Mechanical and electronic solutions (pull-up resistors, filters, wire insulation) don't help.

My configuration.h and configuration_adv.h
BLTouch is enabled. The calibration method is bilinear, 16 points (4x4).
Please set your X_PROBE_OFFSET_FROM_EXTRUDER and Y_PROBE_OFFSET_FROM_EXTRUDER parameters; mine may not work, depending on the mount.
