UNSOLVED Delta calibration give wrong z height

Hello folks,
Need advice.
After doing the delta calibration I get less Z height than it actually is. Due to this problem, the first layer does not stick because it prints too high
Real heigh for perfect first layer is: 514.250
Calibration calculates that height is: ~513.680 I calibrated the trigger heigh several times.
 The number of calibration factors or points does not give a different value
 I even made corrections for each point in bad.g
 I try to disable for G30
;G1 Z5 F6000 ; move down a few mm so that the nozzle can be centred G90 ; absolute positioning ;G1 X0 Y0 F6000 ; move X+Y to the centre
No matter what I do, I always get a bad Z height: ~513.680.
The current solution is to perform the calibration, save the parameters to the M500 and manually change H to 514.250. Then prints well and at a good height.
But it doesn’t suit me, a solution is needed. Why auto calibration give wrong z height?Sensor Bl touch.
