Adjusting the hole diameter

Because holes on the printer seem to get smaller and smaller due to the different shrinkage of the materials, I have created a print test for a desired hole diameter of 10 mm.
A plate 80x20 mm with 5 holes with increasing diameter.
10,0-10,1-10,2-10,3-10,4.
The material is ASA, which has been completely calibrated.
The measured values are :
9,85-9,96-10,05-10,16-10,25.
On average 0.15 mm too small in diameter.
I set the xy-hole-contour-compensation in the Bambustudio or in the Orca Slicer under Quality/Precision to +0.15 mm, which is the average value of the measured holes.
Reprinting the part with these settings gives the following values:
10,14-10,28-10,35-10,47-10,56.
What is wrong here?

Seems like 0.15 was added to the radius, not diameter. Try half the value?

x/y compensation for holes or contours must be entered as a radius value.
This means that if the diameter dimension is 0.1mm too small, 0.05 must be entered for compensation.

Hi … did you reach a conclusion to achieve accurate hole diameters in BamBu Studio ?
If yes, how did you achieve it please?

Regards …
