3.5.0-rc2 G32/G30 on linear delta crashes into bed

DavidG_68kg_PLA

Having a linear delta with a max. build volume height of 1704mm, probe is 19.0mm high.
When starting the first G32 routine, the sensor crashes into bed. Then I reduce the machine height by 19mm, each time saved with M502&M500. After a restart, the probe is to high by those 19mm.
Then i change to 1704 again, execute the config.g, M502, M500 and the G32 proceeds fine. After a restart it will crash again, until I reduce the machine height by the sensor offset again.
It worked seamless on 3.4.4 before.
bed.g and config.g attached.

Thank you for your support!

@DavidG_68kg_PLA I've not used a delta before what probe are you using? it sounds to me like you need to reset your G31 trigger height to zero and then re-measure your Z trigger height.

@DavidG_68kg_PLA Please upgrade to 3.5.0-rc.1 and test again.

Okay, I updated all components, but the dwc on the pi (im running sbc mode) doesnt want to update.
so far the issue with the crash still happens.

To analyse why the dwc doesnt update i followed the trouble shooting, but i dont know wheres the knowledge about the update-issue in this answer:

@DavidG_68kg_PLA said in 3.5.0-beta.4 G32/G30 on linear delta crashes into bed:

Having a linear delta with a max. build volume height of 1704mm, probe is 19.0mm high.
When starting the first G32 routine, the sensor crashes into bed. Then I reduce the machine height by 19mm, each time saved with M502&M500. After a restart, the probe is to high by those 19mm.
Then i change to 1704 again, execute the config.g, M502, M500 and the G32 proceeds fine. After a restart it will crash again, until I reduce the machine height by the sensor offset again.
It worked seamless on 3.4.4 before.

Same issue still exists on 3.5.0 rc2.

Now i'm back on 3.4.6 and the same crash behaviour happens when executing bed.g via G32, after executing M502 and M500 (or reconfigguring the machine because auf mechanical changes).

I executed G32 with the probe only electrically attached but not mechanically, and the machine doesnt take the 19mm probe height into its calculation, as it travels with the tip of the nozzle to Z = 5 (=0 + 5 dive height)

; Z-Probe
M558 P8 C"^121.io0.in" H5 F300 T18000                            ; set Z probe type to switch and the dive height + speeds
G31 P500 X0 Y0 Z19.0                                             ; set Z probe trigger value, offset and trigger height
M557 R480 S48

After some test and trial with different M500/501/502 combinations with a crash on each G32, I executed G29 Mesh Bed Levelling, which works perfectly fine!

After that first G29 also the Delta Calibration via G32 takes the probe height into calculation and works without crashing.

@DavidG_68kg_PLA confermo che anche la rc3 ha lo stesso problema, la sonda si schianta sul piano, ho notato che il sensore a video legge anche in object model viene letto il sensore, ma quando si lancia la calibrazione della delta si schianta e si trascina il sensore

allora,ho rifatto la sd della stampante ed ora funziona
