Thanks for the advice. I will take that into consideration when I make a new part. What is confuses me is why the most of the dimensions I have used have come out extremely accurately including holes.

I have been printing with my Ultimaker for about a month now and have faced many technical problems along the way however I have managed to make several nice accurate prints. My current issue has come up when trying to print a .250" slot in a extruded rectangle. The hole has been coming out about .020" to small and I feel ive done everything I can to correct it such as using 3 different slicers, measuring the .stl file, remaking the model all together in Solidworks, uploading new firmware, tensioning the belts, looking at the dimensions in the G-Codes themselves and probably a few other things I cant remember. Specific details bellow The model was created and exported as an .stl from Solidworks .stl was sliced in Cura Slic3r and Kisslicer prints were made from 210 to 225 C multiple filament extrusion percentages used for perimeter, first layer and fill Same result every time. .020" small but all other dimensions look perfect Any help would be greatly appreciated Zac
