 These are the profile of your thermistors. Generic profile are often "1" which is "100K Thermistor". If you can get exact brand and thermistor type for your hotend/heated bed, use that particular number/value/profile. Because each thermistor has their own characteristics to report temperature.
 
 This is crucial to ensure exact temperature measurement. If you're unsure, just use 100k thermistor for `temp_sensor` and `temp_sensor_bed`

 ## Z Probe Options
 
-`//#define Z_MIN_PROBE_ENDSTOP`
+```cpp
-
+//#define Z_MIN_PROBE_ENDSTOP
+```
 If you want to use both probe and default z min switch for your 3D printer, enable this. However, This requires extra setups to be done. If you're using Ramps 1.4, the probe pins are located in D32 of the aux4 array that used by the lcd panel. You have to change the pin manually from the board pin file for example "pins_RAMPS_14.h" located at `#define Z_MIN_PROBE_PIN  32`. I would change this to pin 19 (z max) since it never really been used. This extra ports is actually the Z Probe that is used for your auto bed leveling.
 
 Another way is to change between these `#define Z_MIN_PROBE_PIN  32`, `#define Z_MIN_PIN          18` and `#define Z_MAX_PIN          19`  according to your board. This is not for beginners.
 
-`#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN`
+```cpp
+#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN
+```
 
 This however uses single switch for your z axis only. If you only want to use z probe for everything related to homing and bed leveling, enable this option. Note that either one of them can be enabled at a time. 
 
 Note to dev; Please make the comment explanation much simpler or the define variable, it's so confusing that reading it again can took me 1-5 minutes to figure out 
 
-`//#define DISABLE_Z_MIN_PROBE_ENDSTOP`
+```cpp
+//#define DISABLE_Z_MIN_PROBE_ENDSTOP

 These inverts the motor movement for each axis. Usually flipping the connector will be okay but if that's such a hassle, just invert these without the need to fiddle with your electronic.
 
 ***
-`//#define MIN_Z_HEIGHT_FOR_HOMING 4 `
 
+```cpp
+//#define MIN_Z_HEIGHT_FOR_HOMING 4 
+```
 This works like how a probe based 3d printer works when homing. Instead of increase z height after x and y has been homed, Z axis are raised first before homing procedure. This is also to avoid from the head crashing to the bed mounting such as screws, bulldog clip and some other stuffs. This works with auto bed leveling enabled and this will be triggered only when z axis are less than defined value, else the z axis will not move.

-`#define Y_HOME_DIR -1`

-
+#define Z_HOME_DIR -1
-`#define Z_HOME_DIR -1`
+```
-
 This tells marlin where the head is at when all the endstop has been triggered. typical setup are all at min position; bottom front left side of the bed. In some cases, some owner puts the home endstops at max position and these needs to be changed if max position are used.

+```cpp
-
+#define min_software_endstops true
-`#define max_software_endstops true`

 These are one of the safety features that prevents manual movement exceeding the below specified value. The head can only move within the specified value below.

+```cpp
-
+#define X_MIN_POS 0
-`#define Y_MIN_POS 0`

-`#define Z_MIN_POS 0`

-

+#define Z_MAX_POS 170
-
+```
-`#define Y_MAX_POS 200`
-
-`#define Z_MAX_POS 170`
-
 Usually the `MIN_POS` are left at 0 value and `MAX_POS` depends on your maximum travel. Setting this too high would risk the printer's carriage crashing to each ends. This needs to be set in conjunctin with home offset eeprom variable to work properly. If you don't want to set using eeprom, you can fiddle with `MIN_POS` value above as a substitute to eeprom's Home Offset.
 
 ***
-`//#define FILAMENT_RUNOUT_SENSOR `
+```cpp
+//#define FILAMENT_RUNOUT_SENSOR
+```
 
 This one is optional yet cool feature to have. An extra endstop switch is required to detect if the filament is present or not and the switch usually in normally closed/open state when the filament is present. If filament ran out, M600 command will be issued immediately.

 ##Bed Leveling
 
-`//#define MESH_BED_LEVELING`

 Bed elevation are not equal and the bed shape might be a bow shaped in the middle when it is hot nor manual bed calibration works perfect on all 4 point during initial setup. This one is slightly more advanced technique of bed leveling process where each point will have their respective elevation values

-`#define AUTO_BED_LEVELING_GRID_POINTS 3`

-
+#define AUTO_BED_LEVELING_GRID_POINTS 3

 This avoids the risk of z probe going out of the bed when homing all of the axis especially when it is the z axis's turn to home. This will bring the z axis probe into the middle of the bed then wil do the z homing to find z position. Disable this `#define Z_SAFE_HOMING` if you're using more tan 1 z axis sensor (probes and switch) and enable this`#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN` if you want to have your printer head to be parked outside of the printing area. These will work together where usign the G28 command will not going to use the z-probe while using the G29 will use the z-probe instead of the default z min switch. If `#define Z_SAFE_HOMING` is enabled, then the z min switch will never be triggered since the head will always move to the center of the bed area.
