The strange homing, once it starts homing, it seems to think I've already touched the limit switch and starts moving away from the limit switch distance, and it alarms with code 8 after exceeding the limit switch distance. #362

Manually pressing the limit switch is fine; it can trigger a hard limit alarm.

This is my limit circuit, connecting X_XW to GND can trigger the hard limit normally. 安安

Based on STM32F407VET6.

"I noticed that the wiki mentioned the limit switch is a normally closed switch. Now, when I connect the limit switch to the normally closed configuration and send $HZ, there is no movement. I have to manually press the limit switch once, and then it moves away from the limit, returns to seek the limit again, and finally completes homing. It's confusing."
