I am using a Mac, OS X 10.11.6.

I need some help... Haven't been able to print my first 3D print, or even get the extruder moving.

-I have built/wired the pro B. So far, so good.
-To install the Marlin firmware I rolled back to Arduino 1.0.6 to get around the compile error with later versions --> "using typedef-name 'fpos_t' after 'struct'." Success. - Arduino suggested a more up to date driver for the board --> updated.
- I downloaded Repetier Host & installed. Success.
- I d/l & installed Repetier Firmware x through this link - http://www.repetier.com/firmware/v092/ & uploaded the Repetier.ino file through Arduino. Arduino successfully uploaded but the LCD screen now has only blocked display & constantly make a quiet, metallic screeching noise.

Despite LCD screen issues i tried to print a basic .stl with Repetier Host. If I set baud = 115200 I at least get extruder temperature updates coming into Repetier Host, but when i slice-->"run" it gives me a printing ETA of 6m:35s, but nothing else happens & the log just goes back to giving me extruder temperature updates.

Any ideas? I've spent so long trying to get this to work I need a fresh opinion.

Update - removing/reinstalling Marlin driver fixed the LCD & screeching & I thought it would then be wise to try & print from a gcode file on an SD card.

The result is the same as when hitting 'run' in Repetier Host... the Pro B doesn't do anything. I can see the file on the LCD screen & select it just fine, then i just see the following screen. Looks like the extruder & heat bed aren't getting started/not heating up.

Also - i should add, in case it helps narrow in on the real issue. I can move all axes through "Prepare" --> "Move axis" --> "Move..." so all motors seem to be functioning.

Any ideas?

Did you have the right slicer settings in Slic3r?
You can attach the Gcode file if possible.

Hi Bang,
It wouldn't let me attach the gcode here so i have uploaded to dropbox

Please let me know if you notice anything. thanks - brian.

To further help diagnose, I tried to print one of the gcode files from the prusa drivers file, ABS_2x_3DHubs_Marvin_1H.gcode
...
same result - I click the file (through LCD screen navigation) & nothing happens

Did you set the right parameters(temp for extruder and heatbed) as the user manual told?
Then how about printing via USB?
