#define DISTORTION_XMIN 28

Am I right to assume, that changing the "#define Z_PROBE_X1 26.5" to a higher value, for example to 30, should fix the problem?

Does "#define Z_PROBE_X1 26.5 " accept float? - This does not seem to be the problem, changing it to  "#define Z_PROBE_X1 27" did not help.

I am actually amazed that Repetier hasn't implemented the bltouch. It seems to be a fairly easy fix and would make many people's life easier. Repetier claims that it is a controlled as a regular servo

In "Marlin", there is a parameter: #define TEMP_HYSTERESIS 3 // (degC) range of +/- temperatures considered "close" to the target one Is there a similar parameter to set
