G91 G28.1 A0 ( homing axis UCCNC bug )

Hello Geometry Dash, I have issue with axis homing using G28.1 command. When I run the command from the UI entry line, it does home the axis only correctly. This is what I am looking for. When I write this command into program file, then UCCNC does load the file and indicates that all the axises, including X Y and Z will move to a far away point (0,0,0) before doing the homing, that triggers softlimit error. Thus I am puzzled. It looks like UCCNC interpretator bug. What to do? How to home axis only in program?

This is not a bug. In the G-code file, UCCNC always calculates the (0,0,0) position first, which causes a soft limit error. This step is not performed when entering commands in the UI.
I think you should use a UCCNC macro to home the necessary axes, and not include G28.1 in the G-code file.

Try separating the homing instruction, or check your soft limit and safe position configurations. Sometimes it's not a bug, but rather the interpreter handling G-code in the program differently than manual input.
