This page describes the way to setup this 600W / 220V silicone heat-bed upgrade from 3D Modular Systems . This upgrade is compatible with Creality CR-10, also potentially compatible with Anet E10
- 1 silicone heat-bed 220V / 600W
- 1 static relay
- 1 Grounding kit
- 1 cable tie kit
- 1 spiral cable tie
Remove the glass from your bed.
Remove all 4 screws from your heat-bed
Return your heat-bed
Place the silicone pad so that the holes fits the bed screw holes.
Remove the protective film
Make sure to place the silicone pad so that the power supply cables are placed on the same corner as the original cables.
Note here the location of the power supply cables.
Re-use of the existing wiring
The main purpose here is to re-use the existing wiring
You have several choices here:
- Simply cut the power supply wires (Red and Black)
Make sure not to cut the 2 small white wires!
- Or un-solder them from the PCB bed
Separate the 2 power wires from the temperature sensor.
Insulate the heat-bed
The more efficient way is to use simple aluminum foil for cooking.
Warning! the aluminum foil has 2 different faces
- 1 shiny side
- 1 mat side
Use the shiny face so that it faces the black side of your bed.
The mat face has to face you.
Using a fine cutting device, carefully remove the excess of aluminum and open up the dedicated square holes .
Secure everything using kapton tape.
Kapton tape is specially made to handle high temperatures
It is also a great electric insulator.
Make sure to use proper tape
Place 4 Kapton strips along the sides of the bed in order to properly secure the whole system over the black heat bed surface.
Using a fine cutting device, you can remove the excess of tapes on the corners
Finally place a diagonal strip to secure everything.
Re-install the heat-bed and the glass.
Cut the sheath holding the power wire and the thermistor. Use a simple pair of scissors.
Make sure to cut only the sheath. Avoid cutting the wires inside the sheath!
Use a pair of cable ties to secure the thermistor wires with the bed power wires.
You can use the spiral sheath to secure the wires.
Static relay installation
Remove the blue extrusion cover located inside the left side of the chassis, at the back.
Cut about 8 cm
Static relay installation without cover
Install the static relay using a pair of M4x8mm screw and a T-nut.
Take special precautions on the orientation of the relay. The 3-32VDC side has to be facing the Z axis stepper motor. The 220V side must point toward the outside of the chassis.
Connect the Red wire of your heat-bed that you previously cut and connect it on the « + » terminal of the static relay (terminal number 3)
Also connect the Black wire from your heat-bed (that you also previously cut) on the « – » terminal of the static relay (Terminal 4)
Make sure to take into account the polarity on the static relay!
Wire both Terminals from the 220V silicone bed on the static relay terminals . Here there is no polarity
Make sure to insulate the 220V of the static relay using Kapton tape.
Ground wire installation.
You will need a pair of washer, 1 M4x8mm screw and 1 T-nut.
Take the 2nd ground wire provided
Connect the 2 ground wires at the same location on the chassis, here pointed by the arrow.
The last washer is inserted at the bottom. The T-Nut allows to secure the ground wires on the chassis.
The 2nd ground wire has to be attached under the heat-bed.
Unscrew the adjusting knob under the bed, on the corner near the static relay.
The 2 washers allows to make contact between the ground wires and the metallic side of the bed.
1washer o each side of the ground wire terminal.
The adjusting knob secures everything.
you can use the spiral sheath in order to finalize the wiring.
You can use your heat-bed now.
On the electronic side you have no changes to make.
You heat bed should reach the following temperature
- 60°C in less than 1 minute 10 seconds
- 110°C in less than 3 minutes
