Solved BLTouch will not deploy with M401
-
@joergs5 Yes this is right. I haven not changed the settings yet, becuase first I would like to home the printer.
-
@t3p3tony I have tested it with the other port, but there was the same result.

@inno-3d the core at the top of the BLTouch (allen key rotatable) needs correct position, is the pin movable?

@joergs5 The BLTouch should work fine. At the start, the BLTouch does it's self test.
The BLTouch worked at another borad fine. So i think, that is not the problem.
-
@inno-3d I have no more ideas, only rechecking wiring, and using only the mainboard pins.
-
@joergs5 Ok, thanks for your help!

I’ve had a similar issue where the BLtouch would not deploy even though everything was set up correctly. My issue turned out to be the stepper motor cables creating noise on the servo wire and interfering with communication to the BLtouch.
Have you tried sending M401 with the stepper motors disabled vs with them powered on?

@inno-3d I see you started another thread, I had not noticed that the port should be inverted with the EBOB, as @Gixxerfast suggested on the other thread, try adding a ! to invert the pin definition:
M950 S0 C"!exp.heater6" -
@t3p3tony yes, I saw the solution at the other thread.
Many Thanks @T3P3Tony and @Gixxerfast !!!
This solved my Problem!
