Ok so i have built a 3d printer from old cd rom drives. Before installing the 3d pen(extruder/hotend) i used www.makercam.com to export i file containing a star. With a marker attached the machone successfully drew a star. Now i have the 3d pen but using makercam i am not having any luck. Is there a better way to generate files for my new toy?

  • $\begingroup$ I would like to be able to generate my own files so it will have some functionality but something to test it with would be great $\endgroup$ – Keith Bybee Oct 26 '17 at 1:33
  • $\begingroup$ TinkerCAD may be the way to go for simple exportable 3D prints. $\endgroup$ – IMustBeSomeone Oct 26 '17 at 1:34
  • $\begingroup$ You can easily build, create and design 3D prints and export them straight to a 3D Printer. Used it myself. $\endgroup$ – IMustBeSomeone Oct 26 '17 at 1:34

Try using TinkerCAD!

I'm not advertising here - I have used TinkerCAD in the past for 3D printing. TinkerCAD allows you to easily build and create simple shapes by the press of a button. (I assume this is what you mean by generation)

It is great for testing if your homebrew 3D printer works.

  • $\begingroup$ What gcode sender do you use? I use grbl controller on linux and it seems to only support .nc files i also have ugs but i dont see the file with that either $\endgroup$ – Keith Bybee Oct 26 '17 at 2:20

The g code is generated by a program like slic3r, skeinforge or cura. These programs import a CAD model slilce it into layers and output the gcode required to print each layer.
