描述

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

Actually I have dual Z drivers and invidual Max Z homing sensors. On Lerdge original firmware it's possible using the Ex-Axis function as described in here: https://www.lerdge.com/document/detail/ExtensionOf-ExAxis

Are you looking for hardware support?

No response

Describe the feature you want

Would be nice if on Lerdge K Marlin firmware port one could choose to use Ex-Axis as: a) second individual step generator for Z axis (my setup) b) second step generator synchronized with steps on Z1 (some people use Ex-Axis like this)

This is a picture of my actual Ex-Axis configuration on Lerdge original firmware. Please, take this is consideration as it is the only thing attaching me to the Lerdge original firmware, which is awful. 9e262851-572c-4339-bfbb-6c0ec322d075

研究方向
Review Marlin's existing dual Z axis support (e.g., Z2 STEPPER PIN, Z2 DIR PIN) and understand how EX AXIS is implemented in Lerdge's firmware. Examine Configuration adv.h for relevant defines. Look at M350, M906, and other G code commands for stepper driver settings. Check the issue comments for any implementation discussions.
