• menu > Preheat, select filament type being unloaded
• When up to temperature, menu > 'remove filament'
• It will start to push up and out
  grab ahold of it and pull it out the last bit
• Problems:
• It can happen that the filament gets stuck and won't come out.
• If that happens, increase the nozzle temperature,
  and repeat the unload as many times as needed,
  while pulling (try grabbing the filament with pliers)
  until it will finally come out.
• It has happened that no amount of pulling will get it out. When this happened to me, it was because there was a blob at the end of the filament that would not pull through the PTFE tube. I opened the idler door to discover this. I reached in with a pair of cutters and cut the blob off.
• If this happens, it can mean that your nozzle/heat-block are partially clogged, and you might do a hot or cold pull procedure to clean it.
