SKR Pro + BL Touch 3.1 (BL Touch issue...)

General Discussion
1

Hi All,
Trying to configure my BL Touch 3.1 (Genuine) on my SKR Pro 1.1.
Wiring seems ok, no errors on the pins apprently, but…
When I start the MCU, the BL Touch pins is triggered and come back in place, BL Touch state is a steady red LED.
When I run the “BLTOUCH_DEBUG COMMAND=pin_down” command, the pin goes down, then the BL Touch is flashing red…
Trying next to send " BLTOUCH_DEBUG COMMAND=pin_up", nothing happens, pin stays down and BL Touch still flashing…

Here is my cfg for The probe:

[bltouch]
sensor_pin: !PA2
control_pin: PA1

Any ideas?

When you run BLTOUCH_DEBUG COMMAND=pin_down, does the pin touch the printbed?

yes, and it stays down… should i move the bed down so it does not touch?
Edited: Stupid me… I moved the bed down, and now it works fine…

Again, thanks a lot @EddyMI3D ! You’re a Star!
