[SKR 1.4 Turbo] Change broken servo pin (P2_00) to another pin

[elektroplax]

Hi!

Can someone help me?

I'm trying to put my BLTouch on another pin on my SKR 1.4 Turbo because P2_00 (servo pin) somehow broke. I enabled sensorless homing, so the endstop pins aren't in use and I tried using them. Unfortunately it's not working.

Regards

Or is there any way to fix the servo pin?

Hi ，
Thanks for your information.

Please provide the wiring picture of motherboard and BL touch 

Please provide  the configuration file of the firmware

I will check it

Tested the servo pin (P2_00) with a multimeter and it should work but doesn't. The BLTouch just does the deploy/redeploy test on startup but that's it. Light stays red, no blue light and no self test.

I attached the configuration files for the recent Marlin FW (Bugfix).

Configuration.h Configuration_adv.h

Also: The BLTouch is wired to the board exactly how it's described in this document: https://teamgloomy.github.io/skr_1.4_bltouch.html

By the way: What are the pin numbers for the fans on the SKR 1.4 Turbo?

[elektroplax]

Nothing?

[elektroplax]

Still nothing.

Hi，

Apologize for the late reply.

It can not work in the z-stop pin,since the pin at the servos is not corresponding to the  z-stop.

So the bl touch can not work in  z-stop pin.

Please check

I already changed the pin back to P2_00 (Servo). It doesn't work.
