That little typo there have caused way more cursing than one would think 🤣 . Fat finger-typing on the numpad ended up with them being H2 instead of H0, and of course that fixed all the issues, thanks dude! ♥
with Exec On MCode setting i shut down the sbc with M7722
Shut down isn't hard, but how do you restart it? I have an remote controlled mains adapter to switch the odroid powersupply off/on to restart...
you can restart the sbc also on this way. create an new service and call him reboot. modify the lines from poweroff to reboot andfrom M7722 to M7723 and than you can reboot with M7723. also updates over the sbc should be possible
@dstjohn so i think there has been a bit of confusion here. M667 is deprecated in favour of M669 for setting Kinematics.
Levelling using multiple Z motors is not deprecated but from your config you only have 1 Z motor and the bed.g you posted is try to use the old 4 point compensation, which was replaced with mesh bed levelling quite a while ago.
Very old versions of the firmware compensated for the bed not being level by probing 4 points.
*New versions adjust the bed to be as level as possible by probing a point in front of each independently driven Z screw (or allow a manual equivalent). And separately allow a mesh to be used to compensate for lack of flatness.
Its a problem that you cant reproduce it.
I am using a Duet 2 Wifi v1.04c powered by 24V (Meanwell) and a quiet recent BLtouch (so v3.0 or 3.1)
All genuine and the issue is on my side 100% reproducible.
Wiring is definetly not the issue here. (tested with the clone directly connected to the Duet - shortest wire possible).
2 different BTtouch clones tested with the same issue.
I am pretty sure its a firmware issue.
Tested the BLtouch on exp.heater3 (connected currently) but also checked (exp.heater4 and exp.heater5.)
As the problems disappears on 3.2.0 and comes back again on 3.3+ I think we can say its not a hardware issue.
For your checks, I would suggest to use a different pin and see if the BLtouch works as intended like:
M558 P9 C"^exp.4" 5 F60 T1000
And connect the white pin to the EXP-Pin 4.
Before, make sure that your BLtouch is giving out 0 and 3.3/5V on the white pin (check that with a multimeter). Just to be sure, the BLtouch has no weird short, that is damaging your board.
I'm pretty sure, that the BLtouch will give out 5V if its powered via 5V.
The duet exp pins are to my knowledge not 5V tolerant (only 0-3.3V), so you might need to put a level shifter or voltage divider in between.
Thank you both for your efforts and time, i DID find my mistake after all. You know, sometimes my brain is so crippled that i cannot see clearly. Somehow i added the same offsets to Tool 0 script. All is good now..
