"Must home axis first: 0.000 0.000 15.000 [0.000]" Error After Update to v2.0.2-36-g230929e3

Hello, Machine is a RatRig vCore 3.1. 500mm x 500mm. Has been sitting idle for a few months. Powered up and updated to v2.0.2-36-g230929e3. After update I keep getting "Must home axis first: 0.000 0.000 15.000 [0.000]" error. If i SET_CENTER_KINEMATIC_POSITION command is sent, all axis home and print will run. I have attached the Klippy Log and printer.cfg files. Any help would be appreciated.

I have the same problem, did you find a solution? In my case I can start the machine and go home after executing the "set center kinematic position" macro but it is not a solution.

If you're not on ratos 2.1 yet, highly recommended you do. It fixed mine and Hutch's Old outdated code, as most of us know, will cause issues with anything. @MakerManiac3D

In my case it doesn't work, I had it installed working perfectly with 2.1, and I had to go back to 2.0 since from one day to the next there was no way for me to connect Moonraker with Mainsail. It is possible that it is some incompatibility of my system, but for now I can work, waiting to be able to stop the machine and dedicate maintenance time to be able to solve it. It is not a definitive solution, and it is annoying to have to execute "set kinematic center position" before a home, but the job has to be done. However, thanks for the response.

Hi. I have the same " must home axis first " problem after upgrading to the latest klipper. Unfortunately trying to upgrade to the latest RATOS 2.1 didn't go well as I have just too many non standard bits on my RATRIG Vcore 3.1 500, such as CAN bus, to let this go very smoothly, I ending up reverting back to RATOS 2.0. What I have done to hide the problem is to add a homing override section to my printer.cfg as show here. It worked for me but your mileage may vary and it may cause problems with your system. [homing_override] gcode: G28
axes: xyz set_position_x:250 set_position_y:250 set_position_z:250 oh I put it after the base setup section which imports the include file. [include RatOS/homing.cfg]
