Hey, I had some starting with my V6. I could only get very little materials out and it was jammed constantly. Im not completely sure what I did to make it work more or less but i got some small prints out now. However I still have the feeling that Im underfeeding in some parts. I had relativly big spaces between the lines on my top layer (250% of .3mm layerheight .4mm nozzle) and reduced it now to 150% where I get a good closed surface, but I find it a bit small. Slicer suggest 230% as default and I remember printing up to 300%. The infill looks also very thin. http://1.bp.blogspot.com/-X9gm90aM7Ww/U ... CT4222.JPG http://3.bp.blogspot.com/-ka3VHxL336U/U ...
