Auto bed leveling
Hi. Im planning to install an auto bed levelling system: bltouch
I have some questions:
1.- the leveling of my bed now is kind of ok, it is a aluminium bed. But I want to go a step further in automation and include this feature. So question is if repetier fully support bed leveling with bltouch system
2.- I have been thinking: lets asume that bed i not perfectly flat (it is a relaity actually) so the bed levelling makes a bed map and firmware will use this map dureing print to compensate. So for example if firmaware drwas a map of the survafe, I could see something similar to a spikes drawing right. If all this surface map is kept dureing all print, the very top of the printed surface, the top surface of the model I mean would reflect this surface map right? so this last layer would actually not be perfectly flat, will be a reflex of the bed surface, am I right?

3.- if question 2 is YES, is there a configuratin where firmware "vanishes" this map as the printing progress so at the end the top surface of the model is actually perfectly flat?
Thanks in advance

2/ G32 S2 bed levelling assumes a flat surface and will level out any tilt,
however G33 'distortion correction will map a non flat surface and add Z correction, in repetier host there is a display disstotion map option in one of the menu's.
3/ G33 will apply correction to the 1st few layers and will gradually fade, the fade height can be set in the firmware config tool https://www.repetier.com/firmware/v100/index.php ;
Pigeon has done a nice setup video for the bltouch

If now I do a Z home, the Z goes down, probe gets trigered, then Z goes up and then quickly goes like looking for 0,0 position (that is my lower left corner) and at the same time it moves in the x/y direction, it goes down... but in that corner there is screw!!!! one of the screws that hold the bed. I do an emergency stop because if not the noozle will crash into it.
Im lost, I have made sure I followed all steps in pidgeon video, I checked configuration and looks like in the video . I have uploaded my configuration.h file. Only thing not in that file are the offset values wich are: -21.300 for X and 12.000 for Y
