Product description
Aluminum Build Plate was designed to be used as
heated build surface of typical 3d printer with 200 x
200 mm XY build area, it is compatible with MK2,
MK2A and MK2B heat bed PCBs. Material is 4mm
thick T6061-T6 aluminum alloy. Plate has sufficient
thickness to prevent twists and maintain flatness
across whole building area, which is necessary for
first layer of print to stick to the surface. Plate uses
countersunk mounting screws to eliminate possibility of hot end to run into a screw and damage itself.
Another convenient feature is the milled channel
for thermistor installation on the bottom of the
plate. This feature makes assembly easy and clean,
thermistor wiring is hidden in between plate and
heated bed PCB.

Thick 4mm plate maintains flatness across
whole area.
Scratch resistant anodized surface.
Hidden countersunk mounting screws.
Kit uses high temperature resistant silicone
rubber spacers instead of typical springs.
Thermistor hidden in the milled channel on the
bottom of the plate and easy to install.
With short kit you can use your existing MK2,
MK2A or MK2B.

Start assembly by preparing thermistor, wiring, PTFE
sleeves and ferrules for the first step. Cut heat shrink
tube in two pieces each no longer than 20mm.
Put PTFE sleeves on the thermistor leads, then cut thermistor cable to the required length and then put pieces
of the heat shrink tube on the cable wires. Use small
ferrules to connect thermistor leads with cable wires,
lightly crimp ferrules using small pliers.
Move heat shrink tube over ferrules and apply heat to
shrink the insulation tubing.
Attach thermistor with wires, assembled in previous
step, to the bottom of the aluminum plate. Thermistor
assembly should be put inside milled channel and secured with Kapton tape, as it is pictured here.
Prepare MK2B PCB heated bed, power cable, M2 hardware and connection bridge for the next step.
For 12V power, istall connection bridge between PCB
pads number 2 and 3. Install connecting bridge and
attach wiring on the bottom of PCB (resistance pattern
is etched on the top, LEDs are soldered on the
bottom). Use this picture for guidance.

This picture shows how 12V power wiring should look
like from the top of MK2B PCB.
If you use 24V power supply to power up heated bed,
use this step for guidance. Attach power wires to the
PCB pads number 2 and 3. Connection bridge not used
ащк 24V power.
When you have aluminum plate assembled with thermistor, and PCB heated bed assembled with wiring, you
can mount everything on the mechanics of your 3D
printer. Use M3 hardware to mount build palte, consult
with exploded view diagram on page 2 for details.
This is how Aluminum Plate looks like on ORD Bot Hadron when assembly is finished. Use M3 screws to adjust
each corner to the required height.
