arduino 3d printer and laser engraver

I am building an arduino 3d printer and laser engraver. So far, everything has worked out perfectly.(for once!) Now, I need to put the software in. The 3d printer has 6 Nema 17 1.5 amp stepper motors. I am using the Ramps 1.4 shield on the arduino mega. Anyone know how to code it??? The laser engraver has 3 stepper motors (Nema 17 1.5 amp) and they are drivin by the arduino uno with a cnc shield on top. I want to use benbox for the laser engraver and I know you need pronterface for the 3d printer. Thanks in advance!

Start with google, I see plenty of hits on converting a 3D printer to an engraver.

Thanks for your help. I googled it and I came up with this page: https://create.arduino.cc/projecthub/DesiEngineer/how-to-make-a-big-3d-printer-at-home-using-arduino-4a7b79. The problem I now have is my arduino software does not look anything like his. I have noticed this before, but is has never been a problem. This is what mine looks like. . Anyone know how to download a different version?
