G code to set max X and Y

My brain went on vacation leaving me home alone.
What is the g-code command to set max X and Y axes for MPCNC?

It isn’t in gcode (that I know of). It is in the firmware configuration under BED_SIZE.

It only gets used when homing. I think it is set to 200x200mm by default, and it just means that if it has to travel more than 200mm while traveling, then it will stop with a “homing failed” message.

Now the brain came back, Yes it is in code and you cant home when you are out of bounds. That is why I set it up on my previous build
