Notes

David’s IT Garage: Creality Print and Bambu Studio PETG defaults were off on fan and temperature. Read the spool: some PETG has additives for a 205–225 °C range, and printing it at 250 °C strings badly. Dry PETG even straight from the bag; avoid bare glass. Disabling z-hop made stringing worse. PLA and PETG make easy breakaway supports for each other.
