Prusa

Hello,

I am new to this forum and 3d printing.
If I am in the wrong section please let me know.
I am building a Prusa i3 printer.
I have completed most of the frame and fitted the stepper motors.
Before I go any further I am seeking a bit of advice.
Firstly, which controller is the best, easiest to use.
The weak part of my knowledge is the software, so any help will be appreciated.
Next question, what diameter printing material is best.
I am shortly going to make the Hot end so I need to make it to suit the diameter.
On the same subject is there any agreement on the best Hot end design.

Thanks

Tony

I have not got problems with Arduino 2560 Mega + Ramps 1.4 / Marlin firmware. I use 3mm filaments, but perhaps 1.75mm is already more common now. 1.75mm also if you want a Bowden type extruder. 3mm is perhaps better in not slipping when feeding some special filament types to hot end?
