That a lot with both advice, very in deep and detailing.
However, about using AC power for extra size of hotbed. I would like to know the connect method of physical device.
Now I only experience one single board control everything from stepper motor to hotend to bed itself.
But if running on AC power, it should have some sort of connection/signal from mainboard that telling new AC device to offer certain power need for hotbed.
As far as I know the hotbed working logic is, it is set to have stable temperature on hotbed. Way of doing it is, thermistor tells current temperature, throught DIP control, then device tell how often, and how much power is given to hotbed.
If this operation is correct, then using AC power for hotbed can work individually without signal/connection from mainboard. Let say, if I want to have 78 degree temperature stable one. Then I just need to have individual device with thermistor feature, and simply have a feature on this device that I can adjust a designated temperature, or even have add on DIP manual control. Then this device can run by itself without any connection with mainboard. The only bad thing on it is, every time I turn on my 3D printer, I need turn both mainboard and hotbed device on separately. And the information LED (let say if the mainboard have connected one) doesn’t show all information at once, but need two indication/LED monitor telling the complete store of system status.
What should I search for this device?
I am curious to know your way of AC powered hotbed.
Another question is, I am looking for cheap DIY way to build hotbed platform, the components would be a large size of aluminum piece, with hotwire underneath. Do you know what type of hotwire I should use for this.
Many thanks,
