Cannot control 3D printer using pronterface

Using Arduino Motors, Mechanics, Power and CNC
1

I managed to build a CNC using an arduino Uno and it worked. So now I decided to turn it into a 3D printer. What I did was swith the tool for a hotend and the arduino uno for an arduino mega. I installed marlin as the firmware and connected an aditional mottor for the extruder. Everything else stayed the same from what I had on the CNC.

However when I open pronterface it seems to connect and the console shows that it is sending the gcode instructions. but nothing moves. It doesnt even look like it is trying to move but getting stock, it doesnt even react.

Time for fault finding.
Are the motors powered or can You easily turn them by hand?
Have You checked the power supply voltage?
The extruder might overload it.
Check I/O pins for mistakes changing to the mega.

This is embarrasing, looks like it was just a driver out of place. Thanks for the help.
