My Ender 5 heated bed was getting too slow when heating up to the 100 degrees C plus I need to print the high temp filaments I have in mind. Therefore I decided to install and AC/mains heated bed and SSR to switch it. It used to take just under 15 minutes to reach 120 deg C, but now does it in under 2 minutes. A huge improvement! Not every printer needs it, but for those that have slow heated beds, this is a game changer. I will be adding a new mains powered chamber heater next, then the printer will be complete.

Safety warning: Mains electricity is high voltage and can kill you. Consult a professional before attempting these procedures.
