After remounting the bed I was pleased to see that it all just fits without needing to make any further changes. The wires and the thermocouple were attached with capton tape. Note that the MOSFET board requires 12V to turn on and so I used a simple voltage divider to drop the 24V down to 12V. The MOSFET board was connected directly to the power-supply and switched with the relay output of the temperature controller. Note that you can use a bi-metal switch as a method of temperature control on its own but that they tend to become stuck after a few thousand cycles.

In series with the input to the heated bed was placed the bi-metal switch so that in the even that it becomes stuck on full power it should still stay within a safe temperature range. The resistors were wired up in a 4S-2P configuration so that the current draw from the power supply was around 4.2A for a total of 100W output. After many dozens of hours of printing this method appears to be working just fine. The power resistors were attached with two part epoxy as I did not have any thermal adhesive on hand.

High current ‘Heated bed’ MOSFET break out boardīoth the power supply and the switching MOSFET are overkill for this application but they are what I had on hand.

Omron S8JC-Z15024C 24V, 6.5A PSU that I had on hand.

Omron E5CC temperature controller off AliExpress.

100 Deg C bi-metal switch for safety cutout.

Over-temperature protection independent of the temperature monitoring.

Use a separate power supply to that used by the 3D printer so as to not overload it.

Ability to monitor and set the print bed temperature.

You can purchase an official heated bed for this printer but I want to roll my own more powerful version

Overall I would highly recommend this printer to anyone needing a cheap high quality 3D printer in a small form factor.Īfter seeing this video by Marco Reps I have decided to upgrade my printer to include a heated bed. If you do purchase with a heated bed it is apparently quite slow to warm up and will only reach about 50C if your ambient temperature is low.If no heated bed is used then you are limited to PLA or using large rafts.It does support 3rd party g-code but when doing so you no longer have a print time estimating. Included software has limited slicing options.Can print in Pet-G and ABS without a heated bed if you use a glue stick prior to the first layer.Can be modded for other uses such as a laser engraver.Extremely high print quality due to the use of linear rails and small nozzle sizes.So far I have been very happy with the results. Last year I purchased a Cetus 3D printer which I have now been using off and on for 8 months.
