I run a Creality CR-10S Pro. It's been exceptionally reliable. Rare to have print failures. As others have said, without CAD modeling you might be bored quickly. I also recommend Fusion 360, free version for the personal user and lots of resources to learn it. I use KISSlicer and Cura for slicing, different types of parts behave differently. KS will take learning but I believe the toolpaths are higher quality than Cura and others. Cura has some great features, especially for generating better supports. Material is all over the spectrum, spend a little more and you will get a little more. I prefer Paramount 3D filaments, good price and high quality. Here's a make I did on Thingiverse with the CR-10s Pro. Makes of 3D Printable Jet Engine by LayerShaper - Thingiverse[^] Good luck!

I have a similiar situation when saving an image, no matter what type. It's a local winform client application. When I'm logged onto the machine (I am admistrator) it works fine. When other users without admin rights are logged on, the generic GDI+ error occurs while saving the image. Any ideas on how to get around this? Using Image.Save taking a .png, .jpeg, or .bmp file types, seems to make no difference.
