Friendly reminder that 3D printer are a fire hazard and it's a bad idea to print unattended.
I agree with you mate, but how do you deal with long prints like 12 - 24h? Im printing at home for many years and since day 1 I plan to get some fire protection like ampoule. There are no signs of fire hazard in OPs failure, but your comment made me think again and maybe Ill stop being lazy and cheap. Gonna do some research right away
Once you've seen how the heater cartridge melts the aluminium hotend and liquid aluminium setting everything on fire, it drops onto, you never print unattended again! For longer prints I always wait until the weekend, before starting it. As well I pause the print and turn heatbed and the nozzle heater off, before heading to bed. This method isn't perfect, as it adds another possibility for failures, but until now it worked everytime. My last print succeeded after ~28h (print time only) this way. Another option is, to divide your model into smaller parts, which are easier to print and glue them together, when everything is finished.
I was just thinking anytime you can make something more modular, do it.
You can set up your printer in the same area you work in (if you work from home), and audio fire alarms can be used
My father used a web camera and a remote controlled solid state power relay on his tabletop CNC that he locked away in a separate room so he can look after it
