软限制和伺服 #600

问题是否可重复？
是的

什么情况下会出现bug？
我正在使用 ESP32 Dev Controller v4.1 进行测试。我还在 Z 轴上使用伺服而不是步进电机：

#define Z_SERVO_PIN 		    GPIO_NUM_2
#define Z_SERVO_RANGE_MIN	    0.0
#define Z_SERVO_RANGE_MAX	    360.0


// Temporarily enabled positive machine space because I don't have limit switches, but I still 
// want to use soft limits.  I "manually" home before powering on the ESP32 (i.e. by moving the
// gantry by hand to machine zero).
#define HOMING_FORCE_POSITIVE_SPACE

启用软限制后，我无法行驶超过 Z100。似乎system_check_travel_limits()inSystem.cpp 正在检查移动是否会在 outside $Z/MaxTravel。默认情况下，$Z/MaxTravel是 100。

我本来希望针对伺服系统检查Z_SERVO_RANGE_MIN软限制。Z_SERVO_RANGE_MAX
