Printing Help

Looks like your bed is not level this should be done before any other calibration. link--> wiki dot solidoodle dot com slash leveling-the-print-bed <--- hope this helps, it is amazing what small differences make in the final appearances.

forum software won't let me put in /'s or .'s   :-((((

z offset screw is a coarse adjustment.  Fine adjustments are made with the 3 leveling screws on the bed  ; 2 front, 1 rear.  Use the manual controls to move the head around to all the corners and move the screws to raise/lower it.  Make sure the bed is heated so you don't have to factor heat expansion/contraction.

And even if it's a coarse print, print the thumbscrews (http://www.soliforum.com/topic/242/thum … m-beneath/) and superglue them to the underside of the screws under the bed.  Makes adjusting a pre-heated bed so much easier.

Use paper method to adjust the leveling screws until the nozzle is the same distance from the bed at each point.  Then watch the first layer and adjust the Z screw until it looks right - http://solidoodletips.wordpress.com/201 … st-layers/

Is there any way you can post a video, maybe a youtube link?  There is something very wrong.  The giant blobs at the ends of the raft make it look like the printer is standing still for awhile when it should be moving on Y, as if you have something like a few mm worth of backlash.  Are the belts tight?  Are the motors making grinding noises at each end of the raft lines?
