1. The quantity of burn in layers including transition layers are too many. Causing them to bleed into the support shafts. Or your raft is too thin. You want a 1.0mm raft min.
    • This can also cause an issue of hard cured resin next to soft cured resin causing raft separation.
  2. Your burn-in layer UV exposure is fine but your supports shafts are undersized.
  3. Your lift speed is too fast.
  4. You have bad resin. Bad resin could mean, not mixed well, a bad batch or ECO resin.
  5. Energy supply inconsistent 

This kind of error could also be caused by an inconsistent energy supply from your network. Try moving your machine to another outlet which you know is not within the same electrical line.
