Sorry, I don't get it with the X Delta. You have activated the 3 Point method, right? Where did you measured the Z offset? In the Middle of the bed or at 0/0?
If you measured the height at 0/0 and for example the Z Offset at this point is 0.5. and the nozzle scratches on the bed at 180/180, do I have to choose a positiv value for the X Delta?

I will post as much pictures this evening as possible.

I have a positive value and everything is working fine.
If you want, check my configuration file, maybe it will work for you?

Yes on my SmartRaps I use a positive value as well and a negative on the MagikMakers and i3 machines. But all of this depends on how the probe is setup and we have not seen clearly how this particular machine is setup. The photo shown is not clear on how the sensor is working.
As we all know, there are many different SmartRap variations now, and some are using very different probing systems and more are coming.

I'm terribly sorry, but I forget to make some pictures of my build, I will implement them this evening.

I tried the negativ value of the offset: It's scratching on the heatbed. But finally I think the probing works much better than before. I got the tipp to clear the EEPROM with the following code:

/*
* EEPROM Clear
*
* Sets all of the bytes of the EEPROM to 0.
* This example code is in the public domain.
*/
#include
void setup()
{
// write a 0 to all 4096 bytes of the EEPROM
for (int i = 0; i < 4096; i++)
EEPROM.write(i, 0);

// turn the LED on when we're done
digitalWrite(13, HIGH);
}
void loop()
{
}

So I was able to enable the EEPROM Setting in the firmware.

Unfortunately I only can print small pieces in the middle of the bed (That is where I defined the Z Offest)
at the Position of 10/10 the layers don't stick, because the nozzle is to far away from the bed. At 180/180 the nozzle scratches on the bed again. at 90/90 everything is fine.

I tried to play a bit with the Delta X adjustment, but it did not worked for me. I tried values from -3,9 to 3,9, but the behavior did not changed. Only small pieces.
I'm using the Probing version of the smartrap build 0.491 from github/thingiverse.
