Unknown rows in Configuration.h

DBSDBS

Hi Folks,

I'm traing to tune up mu printer and read a lot in the Firmware settings. When I compare my current Configuration.h with the new ones that I made, I found some differences for wich I can't found any descriptions, nor where from they come:
.
The first groupe is this:

#define ZHOME_HEAT_ALL 1
#define ZHOME_HEAT_HEIGHT 20
#define ZHOME_X_POS 999999
#define ZHOME_Y_POS 999999

The second is this:

#define Z_PROBE_Z_OFFSET_MODE 
#define UI_BED_COATING 

#define ZHOME_MIN_TEMPERATURE 0

#define Z_PROBE_Z_OFFSET 

I guess, thous settings are important too, but I'm not sure how they will change the work of the printer. And because I'm affraid to made any changes without knowing what exactly I do, I ask for some help.

Thanks in advance

P.S. My Z probe works, but I'm not sure is it works correctly.

First group is only important for home order HOME_ORDER_ZXYTZ as described in config/** Set order of axis homing. Use HOME_ORDER_XYZ and replace XYZ with your order. 

 * If you measure Z with your extruder tip you need a hot extruder to get right measurement. In this

 * case set HOME_ORDER_ZXYTZ and also define ZHOME_HEAT_HEIGHT and ZHOME_MIN_TEMPERATURE. It will do

 * first a z home to get some reference, then raise to ZHOME_HEAT_HEIGHT do xy homing and then after

 * heating to minimum ZHOME_MIN_TEMPERATURE will z home again for correct height.   

 * */

Second part:

/* Z-Probing */

/* After homing the z position is corrected to compensate

for a bed coating. Since you can change coatings the value is stored in

eeprom if enabled, so you can switch between different coatings without needing

to recalibrate z.

*/

#define Z_PROBE_Z_OFFSET 0 // offset to coating form real bed level

/* How is z min measured

 0 = trigger is height of real bed neglecting coating

 1 = trigger is current coating

 

 For mode 1 the current coating thickness is added to measured z probe distances.

 That way the real bed is always the reference height. For inductive sensors

 or z min endstops the coatng has no effect on the result, so you should use mode 0.

*/

#define Z_PROBE_Z_OFFSET_MODE 0

Thank's a lot!
