Z leadscrew coordinates are not configured

[KenD]

I just rebuilt one of my printers and upgraded from the Duet 2 to the Duet 3 6HC. I have M671 configuring with my 3 Z axis leadscrews. But I am having a strange problem. I can run the bed leveling but it does not perform any corrections. I get an error that says "This kinematics does not support auto-calibration" When I run M671 in the console I get the following report. "Z leadscrew coordinates are not configured". What I have to do is comment out the M671 line, Reboot, go back and uncomment the M671 line it will work fine one time, Then the next time I have to go thru it all over again. I don't think it's related to my code but here is my M671 line.

M671 X330:650:00 Y300:50:50 S2 ; Set the 3 Z motor leadscrew locations and max correction in mm

@KenD Sorry, Firmware is Duet 3 MB6HC 3.5.0-rc.3

[soare0]

@KenD So you are using G32 in console, or... how? It is not clear for me from your posts, but maybe I did not paid attention enough...

[gloomyandy]

@KenD said in Z leadscrew coordinates are not configured:

M669 K1 ; configure CoreXY kinematics

Your M669 command is after the M671 command. From the documentation:

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

See: https://docs.duet3d.com/User_manual/Reference/Gcodes#order-dependency-26

[KenD]

@gloomyandy Thanks! I overlooked this. I had this right at one time but then my Config.G and Config.Bak got deleted due to the factory 2 test Macro still being on the SD card. Apparently the config file I used to restore it did not have that correction in it
