Heating stage mass production plan-450W heating stage extended heat shield

    The original PCB in the mass production plan of the heating table cannot use a 450W heating plate. Referring to the schematic diagram, the insulation board is not wired. In the spirit of giving it a try, this project allows the 300W heating table to use a 450W Deer Fairy heating plate. The 450W heating plate not only increases the power but also the area. The actual test shows that the circuit is sufficient to support the 450W heating plate. This project is for reference only.
    Considering that the heating table is fixed with multiple screws, there is still a white piao mentality. Two PCBs of the required size are used to form a large insulation board. "This project has been verified";
    the acrylic board in the picture is the acrylic that was made for free at the time of the Lichuang event, not in the original author's project, so the data is biased. If you need acrylic, please go to the original author's open source link to obtain it.
