Aprašymas

The Alu-Heatbed MK3 have features similar to MK2 and you can also operate this board with 12V or 24V.

  • Heatbed with 3.2mm Aluminum Core. Print directly on the heatbed, no need for glass plate. It's a much lighter solution than PCB heatbed + glass, which makes it better for faster prints.
  • Dual power supply. Operate at 12V or 24V. You can use thinner wires when operating at 24V.
  • A central mounting hole on the front side to allow for three point mounting. This is much easier for bed leveling in comparison to 4 point mounting. First level the side with two holes and fix in place, then level the side with one hole.
  • Large solder pads for multiple wires (ribbon cable) or a SMD pinhead connector can be mounted.
  • Pads for SMD thermistor 1206

  • Dimensions 214mm x 214mm
  • 1 layer 35μm (1oz base) copper
  • Resistance between 1.4 and 1.6 ohm for the 12V
  • Resistance between 5.0 and 5.4 ohm for the 24V
  • 100 degree Celsius possible for both 12V and 24V
  • With 15V on the 12V terminals will maintain approx. 115 degree Celsius without regulation
  • Running 24V on the 12V terminals will heatup the heatbed to 100 degree in only 2 minutes (Your printer controller will regulate the power to the heatbed in order to get your preset temperature.)
  • 180 degree Celsius max. temperature

When connecting the heatbed in the 12V setting it is important that you connect solder pad 2 and 3 directly on the heatbed.

Recommended NTC: EPCOS - B57621C104J62 - THERMISTOR, 100K "or whatever thermistor you normally use."
