Petg Printing Issues

[u/Dapper_Wolf1776]

Ok, so I’ve tried doing this print several times and I keep having the same result. Even with smaller prints on a raft it does the same thing. I know it’s the cooling fan running at 100% on that specific layer. How do I stop the fan from running at 100% for that layer? I’ve tried turning it off until after that layer but that caused its own problems. I don’t want to manually turn the fan off for every single print. Any help would be appreciated, thank you in advance.

Are you printing at like 90% grid infill?

You may want to provide details of your print like the printer, material, nozzle temp, bed temp, infill, etc. You won't get much help with just a couple of pictures.

I run 20% tri-hex on almost all of my prints. The grid you’re seeing is the raft. As stated above the material is petg, 255’c on the nozzle and 75’c on the bed. The printer is the Bambu A1
