BLTouch will not deploy with M401
-
Hello,
I have a Problem with my BLTouch. It will not deploy!
I have checked the wiring. It is definitely connected right.I have not a config-override.g file inside the system. I have also updatet the firmware to the latest release 3.3.
With the M401 Code, the BLTouch will not deploy. Do you have any Idea, why?
Thanks for your help!

@t3p3tony yes, I saw the solution at the other thread.
Many Thanks @T3P3Tony and @Gixxerfast !!!
This solved my Problem!

Your configuration looks correct. Does the BL touch carry out its self test when powered on?
I know you have checked the wiring but please share a photograph.

@t3p3tony yes, the bltouch does its self test when powered on.

@inno-3d said in BLTouch will not deploy with M401:
M557 X15:595 Y15:595 S20
one thing to mention is that your setting are ((595-15)/20+1)*((595-15)/20+1)= 30 * 30 points = 900 points, which are more than the 441 allowed.
And the G31 P500 X0 Y0 Z2.5 the XY offsets are probably incorrect (unless the BLTouch is at the nozzle position).

@inno-3d that port on the expansion breakout board is at 5V signalling level so should be fine with even older BL touches. Can you try the other PWM port on the expansion break out board (heater 6)
-
@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!
