BLTOUCH not working

Hi,

my BLTOUCH Setup ist not working. The hardware config looks like good, because with a downgrade to the original firmware "Ender-3 Pro - Marlin2.0.1 - V1.3.1 - BLTouch - TMC2225.bin" works BLTOUCH without any problem. But on this firmware I don't have my filament sensor.


My Setup is:
Printer: Ender 3 Pro
Board: 32 Bit 4.2.7
Adapter for BTTouch: Pinboard A
Marlin-Version: 2.0. Bugfix from 31.12.2020
Compilng Config: As Attachment: Configuration.h Configuration_adv.h
BLTOUCH-Sensor:


Board-Setup:


When I am comiled Marlin without errors, then I can not conrtol the BLTOUCH-Sensor. Nothing ist moving. Only the checkup on power on is worklich well.
I think my config is wrong, but I don't found a good tutorial how I can enable BLTOUCH with the "Pinboard A"-Adapter.

Do you have an idea?

Thx for help.

Thomas

Marlins default is to use the 5 pin bltouch port



To use that break out board (which is really for 8 bit machines) you need to add #define HAS_PIN_27_BOARD to your Configuration.h
This will disconnect your LCD buzzer and use that pin as a PWM control of the bltouch
NB this is only in bugfix. (at this time)

If your running older code you will need to change your pins file

#ifndef HAS_PIN_27_BOARD
  #define SERVO0_PIN                        PB0   // BLTouch OUT
#else
  #define SERVO0_PIN                        PC6
#endif

#ifndef HAS_PIN_27_BOARD
    #define BEEPER_PIN                      PC6
  #endif
