Hi Ray,

The recommended settings for scaffold soluable are as follows:

  • Print Temperature: 215°C
  • Bed Temperature: From 20°C to 55C ideally, but will cope with bed temperatures as high as 110°C
  • Print Speed: ~50mm/s
  • Support Infill: ~15%
  • Support Angle: 45° & -45° (create a crosshatch pattern)
  • Dense Solid Layers: 3
  • Dense Solid Infill: 90%
  • Upper & Lower Separation Layers: 0
  • X/Y Separation Distance: 1.0mm to 0.50mm depending on the material and how well calibrated your nozzle offset is
  • Support Angle: 46° and up
  • Support Pillar Resolution: 1mm
  • Raft: Yes

You will also want to make sure that you keep the PVA dry i.e always store in a airtight container with silica gel. Also avoid keeping the hotend at an idle temperature when waiting for the other filament to be printing as this can degrade the filament.
