G32 error while bed leveling

Q2101

I have a printer with a 3 motor Z-Axis and the pivot point connections are kinematic mounts. I keep getting an error when I have the duet3 6HC attempt to level the bed with the G30 commands. It will probe the correct locations (as close as I could get the sensor, a BL Touch, to the pivot points), however when it finishes the last probe, it kicks out the following error:

G32
Error: This kinematics does not support auto-calibration

I thought I setup the config.g and bed.g files correctly with the pivot points and probe points but it seems I’m missing something. It also doesn't seem to be moving the probe to the center of the bed during the initial homing even though the homeall.g file seems to be subtracting out the offsets. If i manually input the offsets it will put the probe where it should be.

What am I missing?

Below is my bed.g, config.g and homeall.g code

Below is bed.g, i commented out the while loop to see if that was the cause of the issue

Does your bed.g work if you remove the indentations and run it without conditional gcode commands?

@Q2101 said in G32 error while bed leveling:

; Kinematics
M669 K1 ; configure CoreXY kinematics

Order dependency
M669 must come earlier in config.g than any M671 command.

Q2101

@Phaedrux

I did not notice the order dependency on the M671 command, that is most likely the issue. I'll move that command around and see what that does tomorrow after work. Thank you for pointing that out.

Q2101

@Phaedrux

The M671 command being in the wrong place was indeed the issue. I also had to adjust the maximum allowable correction to 2mm. Thanks again for pointing that, it would have taken me a while to find it.
