The holes where orgin to small and with a positive correction you make them smaller than small.
The issue is constant, my big prints with a diameter of 50 , 60 and also 120 mm have the same declination: walls of 3.00 mm are 3.10 to 3.50 also as screws-holes of 6.00 mm were down to 5.60 mm. What is accurate enough for my applications.
I have well done!
What I have changed?
1. reduce the ExtrusionWidth to the nozzle diameter (0.30 mm ; my 0.60 nozzle doesn't work at the Moment
2. scale the object to 101%
3. horizotal compensation to -0.20mm (thats not enough, the new meassures are to accurate but they need a little play to use in a commode way.
meassured the object, standing upright on the printtable in print-preview >>> Cross Section View >>> I can read out the Z-high of the beginning and the ending for length, width, holes, hexagon. The difference is the desiered value for them from the sliced STL.
Long way = 33.50 mm
short way = 19.10 mm
rod - base = 13.10 mm
hexagon diameter (diagonal) 6.30 mm
holes = 3.30 / 3.10 / 3.30
The printed results:
object long way 33,30 mm
objekt short way 18,90 mm
hexadon diameter 6,03 mm
rod-base = 13,10
holes diameter 3,29 mm (the center-hole
I can't meassure in a right way, downside there is the FirstLayer an upside it ist dipped into the hexagon)
This values need another playing with scaling and compensation, but this is the way. For the moment!
Anyway, that can't be the final solution, Simplify is requested to do their homework ...
