I would have never done this 10 years ago with the garbage printers that were pieced together like science projects rather than finished products.

But a modern enclosed bambu printer is a much better engineered device. Bambu is mature enough as a company that they've issued formal recalls for device issues before. This would never happen with the aliexpress specials that used to dominate the market.

Bambu printers (and other reputable modern printers) are being run unattended at scale all the time without issue.
