Just wanted to see if I could get some input from those of you who have run SLP pipes on a 7MM. The motor is stock. First off, I need to change my HG's(right now only 1 layer). Should I go back to stock or 2 layers? I am setting up this machine to their spec sheet which I understand is real close. one question I do have is on the helix choice. They say to use a straight 45 deg. . Just wondering if their is a multi angle that worked good with this set up? Any other info would be greatly appreciated. Thanks
