BigTreeTech Mini UPS V2.0 - 12V Power Out Detector

hen 3D Printing a beautiful masterpiece with complex details and extremely challenging parts like overhangs and bridges, there are few things worse than being hit by a power outage just as the print is nearing its end. And with loadshedding being quite a prevalent part of our lives, as well as other potential power problems that could strike out of nowhere, this is a serious concern for someone who loves to Make, but hates to waste filament. This is what gives the BigTreeTech Mini UPS V2.0 - 12V Power Out Detector such a solid value in our country, despite being relatively cheap to buy, as it can help protect your masterpieces from complete disaster in case of a power outage, and ensures that your 3D Printer will have just enough time to save the current progress into memory and move the hotend out of the way to prevent burn spots.

This handy little module is relatively easy to install, and connects to both the 12V Power Supply of your 3D Printer, as well as its Controller Board. Then, once it detects that the power has been cut from the power supply, it sends a signal to the motherboard, while also providing a tiny amount of stored power from its capacitors, after which the motherboard just enough stops printing, saves the progress, and moves the hotend slightly upward. Then, once the power has come back on, you can utilise the print resume functionality on your 3D Printer to find that stored progress data, get back into the right position, and then carry on printing like nothing had ever happened.

Compared to many other Power-Out Detectors, such as the MKS 220DET Power Out Detector, this module is clever in the way that it also features some onboard capacitors, which is how it manages to lift the print head even after the power has been cut. This is fantastic, as it helps to prevent the print head from burning the print on the spot where it’s left standing, and while the print-resume may not be absolutely perfect, and could leave a small line around the print on that layer, such a minor artefact is quite easy to fix, and is certainly much better than a ruined print that ends up going into the recycling bin. So if you’re tired of spoiled prints from power cuts, whether it’s the loss of an entire print or just a burnt black spot on a beautiful model, the BigTreeTech 12V Mini UPS V2.0 is an awesome upgrade that can save you from a lot of headaches, heartache and wasted filament.

Please Note: The BigTreeTech Mini UPS V2.0 - 12V Power Out Detector is specifically designed for 12V 3D Printers, so be sure to double check your PSU power rating to ensure that you are getting the correct version. Alternatively, if you have a 24V 3D Printer, we also stock the BigTreeTech Mini UPS V1.0 - 24V Power Out Detector, which is similar in design but is made to accommodate 24V Power Supplies instead.

When dealing with any power-related modules, it’s firstly important to remember to disconnect all incoming power before doing anything, and of course use all of the necessary safety precautions to prevent dangerous shocks. With this in mind, we've included some handy resources in the images above, showing the connection diagram, as well as a physical connection demonstration showing what's required to get the full power outage detection functionality of the BTT Mini UPS V2.0.

As one of the rising stars in the world of 3D Printer Component Research and Development, BigTreeTech have certainly hit the ground running, entering the market in 2015 and spending their early stages primarily learning, researching, testing and developing, before producing some truly impressive results. From simple but effective upgrades to standard parts, all the way through to completely custom parts that no other brand offered at the time, BigTreeTech now have an incredibly diverse range, with almost no area of 3D Printing being left out.

Some of BigTreeTech’s most notable additions to the world of 3D Printing include the SKR Motherboard Range for numerous different 3D Printer models, the awesome TFT Touch Display Range with fancy features like dual-mode operation, as well as their very impressive Stepper Driver Range that cater to all tastes and preferences under the sun. And of course, to top it all off, BigTreeTech also have a sister company named BIQU, and we must admit that they have been producing some pretty impressive (and low price) 3D Printers, with the BIQU B1 possibly becoming a new rival to the Ender 3.

Of course, it’s easy to see that BigTreeTech are modern masters of 3D Printing R&D, and while we do still have a lot of different parts that we want to test out from them, so far we’ve been extremely happy with what they’re capable of producing – all while fitting into same kind of hobbyist budget that they used to operate on as Makers and Tinkerers themselves.
