CR-10, 220V 600W

Heat-bed upgrade – 600W / 220V for Creality CR-10 / E10 3D printer


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

Upgrade content

  • 1 silicone heat-bed 220V / 600W
  • 1 static relay
  • 1 Grounding kit
  • 1 cable tie kit
  • 1 spiral cable tie

Heat-bed disassembly

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

You should have a red enclosure provided with the static relay . You just have to position the static relay on the side where the silicone bed power wire are going out.

If you have this red enclosure you can skip the next few steps that tells you how to connect you heatbed to you static relay.

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.

insert the screw and the washer inside the ground wire round terminal from the heat-bed.

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.

That’s all!

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
