I have a new FlashForge Creator Pro. Have made a few prints with excellent results. I was having trouble at the start of the raft making so I turned the cooling fan off and the problem went away. My question is “when should the cooling fan be on?”

Hi there,

As a general rule for PLA prints, the cooling fan should be off for the first layer, then on after that to help with cooling (PLA likes to cool as quickly as possible).
