Humorous Stories and Lessons Learned

1. The Filament Mishap:

A user left their printer unattended with a large spool of filament loading into the extruder. However, the filament got tangled, causing the printer to repeatedly try to force the material through, creating a comical ball of tangled filament and a chorus of grinding noises.

Lesson: Always supervise your prints, especially when loading large spools of filament.

2. The Printer Stampede:

A user attempted to print a large object on multiple printers simultaneously. However, the printers' power supplies overloaded, causing them to cycle off and on rapidly. The sudden start-stop movements created a chaotic "printer stampede," with the printers colliding with each other and scattering print parts across the room.

Lesson: Manage your printer loads carefully to avoid overloading power supplies and potential printer damage.

3. The Octo-Fail:

A user attempted to control eight printers with a single OctoPrint Multi instance. However, the excessive load on the server caused the entire system to crash, resulting in a complete printing failure.

Lesson: Use realistic expectations and consider the limitations of your hardware when managing multiple printers with OctoPrint Multi.
