F: CalibrationT: Feature Requestgood first issue

描述

Is your feature request related to a problem? Please describe.

No response

Are you looking for hardware support?

No response

Describe the feature you want

In some cases, it would be convenient to be able to change max axis movement without changing firmware, using GCODE commands, then save to EEPROM. For example, if there are no other needed changes in the firmware but you change hardware to allow more clearance or change hotend and thus reduce maximum print height.

Sorry if it was already suggested (I couldn't find any) or if it's actually possible to do.

Additional context

Disabling software endstops is not a good solution for this, as it adds risk of crashing.

研究方向
Investigate the current implementation of machine limits in Marlin firmware, specifically in files like `Configuration.h`, `Marlin/src/module/motion.cpp`, and `Marlin/src/gcode/movement/G28.cpp`. Understand how software endstops are currently handled and how M503 and M500 commands work. Review the discussions in the issue comments for any suggested approaches. No linked PRs exist.
