is A0 on the Arduino. The signal seems quite noisy. I have put a 10uF capacitor across its supply. Maybe add an 0.1uF across its signal? Two values need to be set in Platform.h: If v is the value from the A->D on A0, then: z = v*Z_PROBE_GRADIENT + Z_PROBE_CONSTANT (mm) Z_PROBE_GRADIENT is dependent on the IR proximity device (though they may be consistent enough all to have the same value) and Z_PROBE_CONSTANT depends on how high it is mounted relative to the nozzle. To generate these values, uncomment the bits of code in and around Platform::Spin() zero the Z axis by eye, run the program, and raise Z by 0.1mm increments. Put the raw A->D values in the spreadsheet in the Data directory, and it will give you the values of Z_PROBE_GRADIENT and Z_PROBE_CONSTANT.
