Slope Calibration

This is a simple model to calibrate the printer to print slopes.
Unfortunately, my printer does not yet print successfull.
The first layer print fine, until it prints the first top solid layer.

When sliced with Slic3r it does not detect the top sold fill, therefore instead of using the configured number of top shells it just does 1-2 shells.
Even when sliced with cura it does not print well.

Please let me know if this prints correctly on your printer !
