 # gcode-arrays
-make multiple parts on a 3D printer
+This is a repository for making an array of the same part on a 3D printer, by duplicating the gcode.
+The parts are printed in one go, one at a time, as opposed to all at once layer by layer.
+
+The advantage of this is that if one of the prints fail, the print can be cancelled and you will still have some parts succeed.
+
+Great for small parts if you need them in high volume, like I did in a recent project. I assume you are using a marlin style gcode printer for using this code.
+
+# Usage
+-Start by slicing your stl file in your favorite marlin style slicer!
+-Divide the outputted gcode into three files: start.gcode, middle.gcode, and end.gcode
+-Enter in main.py your desired parameters: x and y GAP for the distance between each part, x and y items for the quantity of parts in each axis.
+-Create a out.gcode file, and run main.py. The program will automatically write in the created out.gcode file.
+
+# licesnse
+I applied the MIT open source license to this project.
+
+Thanks, and enjoy!!
