BigTreeTech Relay V1.2 – 3D Printer Automatic Shutdown Module

Relay Modules are trusty little devices that allow you to break a circuit and program all sorts of fun features or switches into them. Fellow Tinkerers are well accustomed to how convenient a simple relay can be, and the 3D Printing industry was quick to catch on as well! Many modern 3D Printers from Creality and other brands now feature automatic shutdown functions that save on power consumption while the printer sits idle. Now BigTreeTech has made it possible to add this convenient function to your older 3D Printer models with the BTT Relay V1.2!

This BigTreeTech Relay V1.2 Relay is an automatic shutdown module for 3D Printers and works as a 5V relay module with special short circuit detection and support for resume printing. With two signal lines for power failure detection, the BTT Relay V1.2 also features a handy safety feature that immediately powers off to prevent damage on the motherboard. The realy’s main drawing feature is detecting when a 3D Print finishes and safely shutting down your printer for power saving until you return to start another print. A small MCU on the BTT V1.2 Relay is a fantastic addition for stable control and the option to upload new firmware with programmable features like print resume support! This BigTreeTech Relay V1.2 gives great opportunities to Makers who want to add this handy auto shutdown function to an old Printer model or who are building new 3D Printers from scratch.

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.
