just connect the control port to the heated bed connectors on the duet. i use it exact this way.

@Veti but im using the syntax for G29. i tought this behaviour is only on G32.

if i change M557 to M557 X10:185 Y45:205 S20 it goes to Y14.

seems like i dont understand the interaction between Offset and Bed Compensation settings. Can you tell me what to set?

@Veti okay thanks. i replaced it with a G1 X80 Y35 F8000. Homing works as of right now.

still mesh bed compensation is not working. it wants to start at X10 Y0. looks like it ignores the offset.
i saw the bug report for 2.04 yesterday and updated to 2.05 as it said its fixed in the whats new doc.

any idea?

Hello,

i have a problem with auto bed level compensation. i created the config with the online tool and changed nothing to it so far.

my BLTouch ist working as it should. i tried to Z Probe in the middle of the bed and it worked just fine.

if i try to z probe as created by the online tool it tries to go to X-10.5 Y15.5. i do not understand what iam doing wrong. i read trough the wiki at least 5 times.

i'm on 2.05

@Meltex hi sorry for late reply. i honestly dont know how to wire it up the right way.

@CrazyCreator it does not matter. The lerdge board simply gets 5v from the duet and stays on for the time it has 5v connected. No cdg changes necessary.

If anybody came accross the same thing i got a solution. now the baord turns ON with the front button.

Sidenote: it does not matter where you get the 5v from. The pins from the main extension ports are allready if use on my board (bltouch).
