Bl Touch measures not precise

[dc42]

Are you probing with heaters on or off? The magnetic field from some bed heaters in particular interferes with BLTouch. You can add the B1 parameter to your M558 command to turn of heaters temporarily during probing.

Trigger value of 500 is not good for bltouch as well, use P25 in G31 command.

@PaulHew unfortunately I don't know the Bl touch version. This is mine :

There is a method to understand the Bl touch version?

Anyway, I want to update the board to the latest (no RC) firmware as you said.

Thanks

[zecchi]

@dc42 I've tried both, with heater on and heater off. No changes.

Thanks

[zecchi]

@aidar ok, I will change it. P500 was set as default.

Thanks

that looks like a clone
Genuine BLTouch have a QR code on PCB

clones are know to be inaccurate

[PaulHew]

Have to agree with Veti, that is definitely a clone.

AntClab BLTouch have plastic pins, not metal. Also they have a plug that plugs into the Touch as opposed to being directly soldered.

Get an original is my advise.

or build something like this.

@Veti unfortunately when I bought I didn't think about this :'(.

[zecchi]

@Veti very interesting , is it precise as is shown in the video?

[Veti]

@zecchi
yes and its not prone to interference like the bltouch. it is not as compact
