Mystified at autobed level probe points

simervillefarm

I am utterly mystified at WHY my home built kosel-ish clone is trying to probe way, way, WAY outside the build plate. I issue a "G28" to home my printer then issue a "G32 S2". The printer goes down to about 20mm above the build plate and lowers SLOWLY until my inductive sensor trips, raises 2mm and trips the sensor again, then it just buggers off on a straight X positive direction and I have to kill the power to the printer to avoid damage. I know that the changes I am making in the Configuration.h are "taking" because I changed the probe from single trigger to double trigger as a test and that seemed to "take". Here is the relevant section of my Configuration.h file

I tried setting the probe points to positive values as well as negative values but ALWAYS well within my 300mm diameter build plate. I am super confused because if I take the print head off the printer and just have the pulleys moving the x tower will crash into the base of the printer.

Help a brother out, I am at my wits end here.

As I pondered this problem further I thought "I wonder if there is something programmed in the EEPROM". Sure enough there it was first probe point was 20,20 second probe point was 1000,1000 :-O. So changed those EEPROM values to more reasonable numbers and now things are acting as expected.
