Z-probe (bltouch) releases too early when doing G29 mesh leveling
-
Hi all,
My z-probe works fine when doing a single point homing, but when I do the mesh bed, the pin triggers at the right point, but releases nearly instantly and hits the bed before the bed has a chance to move away.
Am I missing something?
Thanks
EDIT
another question aswell… The x-y offsets on g31.. if I have y10, does that mean that when the nozzle is at y0, the probe is sitting on y10, or the other way round?many thanks again!

1. I am aware that some users have this problem with the bltouch and clones. Using a higher travel speed (to increase the speed at which it moves up) works for some users. I may change the behaviour in the next firmware release.
2. Z probe offset of Y10 means that the probe is over the bed at Y10 when the nozzle is at Y0.

Thanks!
This one is a genuine bltouch now after I broke the original clone (drove it sideways and bent it off on the bed
).Increasing the speed isn't possible unfortunately as i'd need to increase it by 5x the amount to escape the falling pin. I have a corexy with a heavy bed so although 2x is do-able, I wont be able to outpace the sensor.
Can I suggest maybe a "z-probe reset delay" or something where you could have the pin wait 1 second before dropping again.
Currently, I think it's only a matter of time before the pin drops early enough that it bounces back up and fails

Subscribed as I see the same quirk with mesh bed levelling.
I drop the bed 40mm and then initiate the mesh levelling, which sees it get to the first point without clipping the bed.Ian
