Don’t buy Flashforge unless you want to hate your life. They were the first printer I ever bought and unless things have changed they use a proprietary slicer that’s years behind anything else, and they will claim it works with other slicers…until you discover you need to figure out all the settings yourself, including start and end codes
every phone had a different format, i remember the Razr had a deprecated tool to convert .mp3 to a format it could read and limited it to like…30sec audio snippets?
