Did I read you correctly, you were not able to print anything on an ender 3? Did you install or update the splicer? Use AutoCad? Control bed and extruder temps? I'm struggling to figure out how you can't print on an Ender3.
LOL point taken. The 3D printer is not manufactured using any 3D printed parts LOL
I used Cura for slicing and it makes parts just fine. No AutoCAD....2D drawing programs suck for 3D modeling. I use Inventor (regretfully) and Solidworks for 15 years now.
