Hi .
I tried to change the table heating parameters from 0-1 to PID. I got errors after exiting the compilation.

Look for the phrase "error" in the text file

Please help.

There is no need to yell, or be obnoxious.
No need for large fonts and bold of text

How about providing more information instead of shouting?

What exactly did you change?

you should not comment out #define BANG_MAX 255
The very next line uses the same value for PID_MAX
ie
#define PID_MAX BANG_MAX

Hello again.

As per your advice I uncommented the #define BANG_MAX 255 and the compiler resulted with errors as on attached screenshot.

You have enabled #define PID_PARAMS_PER_HOTEND when you only have 1 hotend.
Comment out #define PID_PARAMS_PER_HOTEND unless you have more than 1 hotend

Hi.
I appreciate your quick reply, yet I'm a little concerned. My idea is to have both hot end and hot bed heated in PID fashion. Now I have "BANG-BANG" control mode and I don't quite like it. Upon your post I conclude that PID heating is not possible for just one hot end. Please advise.

That is not correct at all.

#define PIDTEMP
this enables pid for the hotend(s)

you have one hotend so disable #define PID_PARAMS_PER_HOTEND

It then uses the values from the else part of

#if ENABLED(PID_PARAMS_PER_HOTEND)
    // Specify up to one value per hotend here, according to your setup.
    // If there are fewer values, the last one applies to the remaining hotends.
    #define DEFAULT_Kp_LIST {  22.20,  22.20 }
    #define DEFAULT_Ki_LIST {   1.08,   1.08 }
    #define DEFAULT_Kd_LIST { 114.00, 114.00 }
  #else
    #define DEFAULT_Kp  22.20
    #define DEFAULT_Ki   1.08
    #define DEFAULT_Kd 114.00
  #endif

#define PIDTEMPBED
Enables pid on the bed

uses these values

#if ENABLED(PIDTEMPBED)
  //#define MIN_BED_POWER 0
  //#define PID_BED_DEBUG // Sends debug data to the serial port.

  // 120V 250W silicone heater into 4mm borosilicate (MendelMax 1.5+)
  // from FOPDT model - kp=.39 Tp=405 Tdead=66, Tc set to 79.2, aggressive factor of .15 (vs .1, 1, 10)
  #define DEFAULT_bedKp 10.00
  #define DEFAULT_bedKi .023
  #define DEFAULT_bedKd 305.4

  // FIND YOUR OWN: "M303 E-1 C8 S90" to run autotune on the bed at 90 degreesC for 8 cycles.
#endif // PIDTEMPBED

Having "#define BANG_MAX 255" does not mean you using bitbang
