I downloaded the auto-bed leveling marlin firmware, with roxy's improvements. I have only changed the Servo angles numbers, and the measure offsets from the hot end.

When I perform a g28 the head moves to x0 and y0, then goes out to X: 198.00 Y:143.00 to do the z measurement. If I autobed level, g29, at this point it tries to measure the z off the actual bed.

As I said I took vanilla firmware and only updated the ABL and Servo settings.

Is this a problem with the eprom holding old values? I tried to follow the eprom clearing instructions (adding 499) to my configs, but I was totally lost and it wouldn't compile.
