Install esp32 resource pack

Select ESP32-CAM development board

Select a USB-TTL serial port tool. According to the diagram, connect RX to U0TXD, TX to U0RXD, GND and 5V power supply. GPIO0 needs to be shorted to GND during programming.

Select the serial port on the IDE to get the development board information and test it.

Select WebServer in the example

The default is not the red frame define, otherwise the camera will not be recognized after the burning is successful

Short GPIO0 to GND, press the RST button on the development board, and click Compile.

Burn successfully, disconnect GPIO0 from GND

Open the serial monitor, adjust the baud rate to 115200, and press the RST key

I have done this before, but I want to use it as a recording 3D printed camera, take a picture once a second, and save the data to an SD card.

Then edit the video, right? Hahaha, that's ok, but 3D printing is best done by layer, not by 1s.

There is no way to monitor how many layers are printed, so let's do it once every 1s.

It can be tested. In the gcode of the 3D printer, add a return to the origin after printing a layer, and press the shutter at the origin

Do I need to remove the motherboard or connect the printer to the USB port?
