offset probe
-
ok thanks so here I set the difference of the extruder to the effector?
-
ah, your post just overlapped with my edit. but yes you could do that.
but that makes me wonder if then the probe offset is offset from the nozzle or not; hopefully you can test or someone more experienced can comment on that.

@nemecek said in offset probe:
good morning I don't understand something I have a problem my extruder is not centered on my effector. so for the bltouch offset what do I put? from the effector center to the bltouch? or from the extruder nozzle center to the bltouch?
Decide on where the Head Reference Point is. This can be wherever you like; but on a delta, the centre of the effector would be the natural position. Then define the offsets of the nozzle(s) and Z probe relative to that.
On deltas I advise against using an offset Z probe such as a BLTouch. This is because offset Z probes are affected by effector tilt; and effector tilt is very hard to eliminate completely.

thanks I don't think I understand the first part. google translate is not perfect.
so I set the offset from the nozzle to the probe? then I leave the G10 parameters to define the difference as in the picture? -
@dc42 perhaps you told me that in my case the offset is measured from the center of the effector to the probe even if I have a distant nozzle
-
@bearer thank you
-
@dc42 please can you reply when you have 5 minutes time please? thanks in advance

Hi,
You can specify both a X and Y offset for the nozzle AND an X and Y offset for the probe.
Use the center of the effector (0,0) as the reference for BOTH.
The nozzle offset is done with a G10 command.
The probe offset is done with a G31 command.

@fcwilt ok thanks for the help now I understand. so in g31 I put the distance from the effector center to the probe then in G30 that of the extruder to the effector center

Correct.
Just be sure to get the values correct - be aware of which is plus (if any) and which is minus (if any).
