1 3D Printer Aluminum Heated Build Plate Kit Assembly Instructions

2 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. Exploded View of Build Plate Assembly with Prusa i3 Y Carriage Aluminum Plate design features: 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.

3 Full kit contents This kit contains all necessary parts to assemble ready to work Aluminum Heated Build Plate. Kit includes: 1. One Aluminum build plate. 2. One MK2B dual voltage 12V 24V PCB heated bed. 3. One EPCOS 100K B57560G104F NTC thermistor. 4. One 20mm long heat shrink tube. 5. Four 22 AWG ferrule to connect thermistor to wiring. 6. One 1m long thermistor cable. 7. Two 0.3mm ID 60mm long PTFE sleeves. 8. One 750mm long 16AWG power cable with pre-soldered terminals. 9. Three M2 Screws with Washers and Nuts. 10. One Brass connection bridge for MK2B 12V connection option. 11. Four 9mm long high temp. silicone rubber spacers. 12. Eight 9mm diameter M3 washers. 13. Four Stainless M3 x 25 socket countersunk head screws. 14. Four M3 Nylon insert locknuts. 15. One 40mm long piece of Kapton tape to mount thermistor (not pictured). 16. One Allen key for M3 screws (no pictured). Short kit contents This kit contains only Aluminum Heated Build Plate and hardware. Kit includes: 1. One Aluminum build plate. 2. Four 9mm long high temp. silicone rubber spacers. 3. Eight 9mm diameter M3 washers. 4. Four Stainless M3 x 25 socket countersunk head screws. 5. Four M3 Nylon insert locknuts. 6. One Allen key for M3 screws (no pictured). CC BY-SA 3.0 : RP One Labs 3

4 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.

5 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. This is how 24V connection looks like from the top of the PCB. 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. CC BY-SA 3.0 : RP One Labs 5
