config tweak

slic3r
  extrusion multiplier tweak. I was getting a line thickness of
  0.66mm and slic3r said it should be 0.67, so pretty close. I may
  tweak the extrusion multiplier just a tiny bit more but it should
  be close

  Still getting parts popping up during the print. I need better
  insulation on the bed ;)

Marlin
  Been tweaking the X/Y movements. A value of 100 was just slightly
  over the 20m part size at 20.22mm or so. I brought it down to 98,
  probably going to have to push that up just a tad but this should
  be fairly close
