//////////该配置是为了防止热床电阻太小，长时间加热容易烧mos管，增加这个数字，可以防止mos管过热，但加热时间会增长
// If you want the M105 heater power reported in watts, define the BED_WATTS, and (shared for all extruders) EXTRUDER_WATTS
//#define EXTRUDER_WATTS (12.0*12.0/6.7) // P=I^2/R //#define BED_WATTS (12.0*12.0/1.1) // P=I^2/R
//////////如果你希望用M105命令实时查看挤出机和热床功率，请将这两行取消注释(即去掉代码前的//)
//////////PID温控配置，PID参数设置，需要根据系统情况设置，可以通过 M303 代码调用PID_autotune函数获得基本PID参数，然后参照修改下面的DEFAULT_Kp、DEFAULT_Ki、DEFAULT_Kd，例如：M303 E0 C8 S190，表示获取打印头0（第一个打印头）、目标温度190度、循环调用PID_autotune8次后的相应的PID参数。系统自动生成的PID参数相当不错，可保持默认。当然机器不同，也不一定都有效 // PID settings:

// Select PID or bang-bang with PIDTEMPBED. If bang-bang, BED_LIMIT_SWITCHING will enable hysteresis //
// Uncomment this to enable PID on the bed. It uses the same frequency PWM as the extruder.
// If your PID_dT above is the default, and correct for your hardware/configuration, that means 7.689Hz,
// which is fine for driving a square wave into a resistive load and does not significantly impact you FET heating.
// This also works fine on a Fotek SSR-10DA Solid State Relay into a 250W heater. // If your configuration is significantly different than this and you don't understand the issues involved, you probably
// shouldn't use bed PID until someone else verifies your hardware works. // If this is enabled, find your own PID constants below. //#define PIDTEMPBED //

// This sets the max power delivered to the bed, and replaces the HEATER_BED_DUTY_CYCLE_DIVIDER option.
// all forms of bed control obey this (PID, bang-bang, bang-bang with hysteresis) // setting this to anything other than 255 enables a form of PWM to the bed just like HEATER_BED_DUTY_CYCLE_DIVIDER did,
