G2 pro , calibration impossible!

[lenul]

hi

just buy and mount sucessfully a G2pro single extruder.
Building was quite easy but calibration is impossible...
Motions are OK

first the total high is 196mm, witch is far from 210mm given in documentation.... but anyway it's ok
I have succesfully calibrated X Y Z axis by screwing/unscrewing but the central point is alway too close from the plate, the clearance for script 1 position is 1mm instead of 2mm. .

The parameter DELTA_RADIUS seem to be a "no effect"! it was originally at "+2" I down it to 0 .. the only effect is to decalibrate X Y Z axis!!

that's wrong.... ??

First you should calibrate the 3 points.
Then you modify the "Delta Radius" value when you find the middle is not OK.
The next step is to save the modification in "Control" menu.
Finally disconnect the printer and the computer,then reconnect them.
