I am in the process of building up my first Prusa i3.
Ive got all of my electronics, but still waiting for some printed parts to turn up, so I can complete the mechanical side of the build.
I have wired/ connected the stepper motors and drivers etc. onto the RAMPS 1.4 as shown in the wiki.
At this stage, I only have the stepper drivers and motors wired (No end stops at the moment)
I have loaded the test code onto the Arduino, and all motors work (flashing LEDs and Full rotation in both directions of motors)
I have also uploaded sprinter onto the Arduino, however when I use in conjunction with Repetier host, When I try to Jog the motors, they simply Buzz/ Vibrate.
Is there a setting i need to change in Configuration.h, or is it simply the fact that I do not have any end stops connected, which would be stopping the motors from working in the same way they do during the 'test code'
Any help much appreciated.
