Geeetech A20, A20M Superplate Glass + Heatbed Kit
This kit has a piece of Superplate glass, aluminum substrate heatbed, NTC-0805 thermistor and wiring to hook it up. The aluminum substrate heatbed is 1.5mm thick and works as heat producer and heat spreader. The NTC-0805 thermistor is of high accuracy and reliable wiring insulation.
We choose silicon carbide glass with microporous coating as the building platform for 3D printer, without the need of attaching the masking tape. The silicon carbide glass is of chemical stability, high heat conductivity coefficient and good wear-resistance and can withstand extreme temperature. The special coating is inorganic and has a hardness of 8 Mohs, hence of high durability.
Compared with common building platform, this kind of tempered glass is of better adhesion and flatness and easy to take prints off. Besides, it is easy to clean with water or alcohol.
The heatbed in this kit is soldered for 24V power as default. The pad 2 is soldering to “+”, and pad 3 is soldering to “-”.
The two red wires are for “+”, the middle two for the thermistor, and the two black wires for “-”.
Please refer to the silk-screen on the heatbed.
If you have any doubt, please contact us to check it for you before powering it up.
