Alright, if you want to solve the 'noise' issue, there are two things you can do. It involves either changing something in your stepper driver by soldering a resistor on a specific place (I don't know exactly how it works, but there are enough people here that can explain it to you better than me), or, get the G3D stepper drivers. The second trimpot functions as this resistor, and you can turn it up to where you like to solve the noise your stepper motors are making :)
With the old printer it was annoying that I could hear it while watching TV, with the new printer, I have to turn down the volume and look over my shoulder to see and hear if it's still running, and even with the TV-sound muted I can barely hear the printer in a quiet room.
So, there is a big chance the stepper drivers are making the stepper motors noisy.
Second, I still think Ramps is very good.
Third, I don't think a motor < NEMA17 will give you the torque you need for direct extrusion. Unless it is a geared stepper motor. But even with a NEMA17 motor direct drive is barely achievable. You would surely need to use 1.75mm filament.
I hope this is useful for you to know, and if someone disagrees, please step in! :)
