Based on the images and information you provided, it sounds like you are experiencing a problem with overextrusion on large radius features when printing with your Raise3D Pro2 printer using 1.75mm Ninjatek Cheetah filament and slicing the model with IdeaMaker.
This could be caused by a number of factors as you can read some printers information, such as the extruder not being properly calibrated, the filament diameter not being set correctly, or the extrusion width not being set correctly in the slicer software. To fix this issue, you may want to try the following:
Make sure that the extruder is properly calibrated so that it is extruding the correct amount of filament.
Check the filament diamete
Check the extrusion width
It's also important to note that this is a complex issue
