G32 Error: Probe was not triggered during probing move

@jay_s_uk
with the OOB config the z will hit multiple time on the Z switch when home all:

You'll need to physically alter the placement of the BLtouch to lower it down a bit and probably move the z endstop out of the way. The bottom of the BLtouch body should be ~8mm above the nozzle tip to allow for proper trigger height.

Phaedrux

If you raise the print head higher up and then do a homeall can you touch the pin with your finger to see if it stops z motion correctly?

@Phaedrux

Yeah! thats one part of problem if I touch the pin while homing it will not stop the motor check the video:
https://www.veed.io/view/47fba682-59b9-4054-8d5c-fa732df8e43f?panel=share

the BLTouch wil changing color and at the end it will become red

Phaedrux

Check the continuity of the signal wire. That's usually the white one that would be going to the "probe" input pin.

Thank you so much! @Phaedrux

Great Call! i've inverted 3dTouch white and black wire and now the sensor works.

Now I am Following this:

Now I will like to level the bed and print, i am

homing X (not configured for BLtouch)
homing Y (not configured for BLtouch)
homing Y (not configured for BLtouch)
HomeAll (not sure why the home is in the middle of the bed)
True Bed leveling G32 (should I use this or the other?)
HomeAll (not sure why the home is in the middle of the bed)
Print

I am wondering:

Is that the correct way of leveling?
is there something wrong in my configuration?
I am also wondering why the homeAll is going in the middle?
should I edit also the homeX, homeY, HomeZ?
Is there any video/tutorial/info on how to level the bed?

That's going to depend a lot on your printer. Do you have independent Z motors to do full automatic tilt correction, or do you just have leveling knobs on the print bed?

It goes where you tell it to. G1 X150 Y150 Usually the center of the bed is the best place to go, since that's typically where you will be printing.

What do you want to do with them?

There are plenty of videos on youtube on that subject if you search.

I have a stock Ender3, so Im guessing leveling knobs?

Yeah! thats my curiosity why should I use them

Well they are what dictates what the printer does when you tell it to home an axis. So it moves towards an endstop and sets the axis extents.

@john345463563 said in G32 Error: Probe was not triggered during probing move:

Well the most basic leveling is to use a piece of paper to set the knobs so that the nozzle is just touching the paper.

Thats an amazing article too bad its does not have the instructions for the BLTouch

Phaedrux

What instructions are you looking for? How to use the bltouch to tell you how much to adjust the knobs? That's here: https://docs.duet3d.com/en/User_manual/Connecting_hardware/Z_probe_manual_levelling
