So I have become fascinated with this lately and think I have found my new project..https://www.youtube.com/watch?v=iAkzb1nXzwUI just have to have this sitting atop my toolbox at my job working on the Corvettes. So here is the engine block loaded in Repetier..https://i1050.photobucket.com/albums...ls%20block.pngWhile the above picture is of repetier host I have switched to Prusa Slicer 2.0. This is the new Slic3r and that is what I was using in repetier anyways and I don't really print from usb anymore. And I have nothing but good things to say about Prusa Slicer 2.0. Here is my Black Widow about half way done printing the engine block. ~22hrs in so far..https://i1050.photobucket.com/albums...s3%20block.jpgThe LS engine family are all aluminum engines. So I am printing the block and heads with silk silver PLA so it has a shine to it.
