@dc42 I'm a bit confused.
Let's say i'm measuring Z probe height initially at X0 Y0. I go through the steps 1-9 described in https://duet3d.dozuki.com/Wiki/Calibrating_a_delta_printer section "Measuring the trigger height". I read, let's say, 15.500 at that point. Repeating the steps 7-9 several times show that trigger height is consistent at X0 Y0. I put this value to config.g an do autocalibration.
After calibration i check the trigger height value at X0 Y0 and get consistent result 15.500.
But when i move, let's say, to X50 Y0 and do G30 S-1 i get 15.550. I repeat G30 S-1 several times at this point and always get 15.550. So this is consistent.
I thought that i should add this +0.05 value to G30 in the bed.g file for the corresponding point. Am i wrong?
