3D Printer Heated Bed Use Guide
The heated bed is very important for 3D printing of fixed models. If the temperature of the heated bed is not enough or the heating effect is not good, it will cause the model to warp, which will cause the model to easily fall off the plane and cause displacement or misalignment. So do you know what needs to be paid attention to in the use of heated bed?
Guide:
1 The power supply voltage should be the same as the rated voltage of the hot bed , or slightly higher, not too much higher. If the voltage is doubled, the power of the heated bed will be 4 times the original, which is dangerous!
2 To use a heated bed in a closed loop. It is to have temperature measurement + feedback + temperature control, the motherboard generally has temperature control, so don't worry.
3 What should I do if the temperature of the heated bed rises too slowly? The power supply voltage can be increased a little bit, for example, 12V hot bed , with 15V power supply, the power will be more than 1.5 times the original.
4 The wiring must be thick enough, 20A current, 2.5 square millimeter wire diameter is recommended.
5 Safety precautions: After the heating bed is powered off, the residual heat of the heating bed still exists. Please pay attention to safety and be careful of burning your hands.
