When I bought my 3D printer, it had a slight squeak. The guy selling it ch= eerfully volunteered to fix it with some WD-40, and I just about had to fig= ht him off to prevent him from spraying that gunk on my nice new printer. Just a touch of sewing machine oil at the right spot fixed it. --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
