Bltouch G92 command

[npm1]

Hiya,
The bltouch seems to be inaccurate as a device for homing, because of this, I have to continuously go in and adjust the g92 command for that first layer.

Please help, as the bltouch doesnt seem to be performing consistently enough.
Currently the touch has a 240ohm resistor soldered to it.

This is not what I imagined zhoming and bed levelling with bltouch to be.

Kind Regards,

[resam]

The BLTouch is known to have a large deviation between probings. Mine usually varies by as much as 0.060mm.

I recently upgraded to an inductive probe: PL08N, which is about 10x more precise/repeatable in my setup.
There is also a piezo-disc-based sensor from precisionpiezo.co.uk which is also very precise/repeatable.
Or you can try microswitch-based solutions for homing.

I am never gonna use the bltouch again,
especially since the acurecy is consistently of….
