Hot bed kit

If you can’t heat the hot bed, you can use an electric meter to measure it. The voltage measurement method is as follows:

1. Turn on the power of the printer. 2. Preheat the heated bed.

3. Switch the three-use meter dial to the two-digit voltage range.

4. Use the positive pole (red) of the three-way meter to contact the positive pole of the metal screw head (connected to the red wire) on the terminal base.

5. Use the negative electrode (black) of the three-way meter to contact the negative electrode of the metal screw head (connected to the black wire) on the terminal base.

6. If the meter cannot measure the 12V power output, you need to replace the motherboard to warm up normally.
