BTT Power Shutdown Relay V1.2 - Save your printer from idling all night. Full Tutorial.

Hi, anyone used this with klipper?

Thank you very much for this tutorial . I have a BTT octopus motherboard. For sc detect I am thinking of taking SPI3 5V and GND, for power loss detect there is 3V3/GND/ PC0. Should I take 3V3 or PC0 with GND? When in doubt I stick to the basic function

Ithink you missed how the mins power switch is wired.

Does the system auto-reset when you power-cycle the mains, or is the Reset button absolutely required?

Thank you. I don't know why BTT couldn't have put the complete wiring diagram including mains connections to the PSU in their documentation.

Great guide!, and also great warning!

Ive just installed mine flawlessly. Im just waiting for some connectors and a momentary switch to enable the reset switch and short cirquit detection.
You are legit one of the handfull of guides i found, but im actually able to follow it.
Also great that you dubbed it in english even though the original was in german.

Just a note for the people following the guide! Tripple check the wiring for the PS-ON etc. the ON on on the board side should have its JST connection flipped. for the SKR e3 mini v3 maybe yours too! it was quite fiddly to remove the pins but i managed in the end.

Thanks a lot for your video: I was struggling with the printer shutting down after 20 seconds : it was the signal cable and I had to reverse the GND and SIGNAL. The cables were the ones with the relay, and the card from the same manufacturer ... I could never have imagined that the polarity of the cable was reversed.
😇

Note you can use the cable that comes with the relay board if all you want is power control. BUT as typical of BTT, it's wired wrong. you have to be sure to swap the pins on the E3 board end. Once I flopped the wires on their stock cable it started working perfectly. Never trust any cable sent by BTT to be correct.

Wonderful! Thank you!

Excellent video, awg section for dupont cable ? 24 26 or 28 ? thanks

its not shutting things down really as it leaves the psu on its only shutting the board of witch is pretty much a waste of time as uv goto turn the psu power off manually

I've been searching for this information FOREVER!!!!! You have made my life such easier!

Hi, how to change it from 90c to 50c?

Excellent tutorial! Thank you very much!
(despite the epilepsy inducing flickering 😉)

La video est excellente. J'ai donc commandé cette carte.
Est-ce que vous vous souvenez où vous avez acheté le bouton reset ? Merci d'avance. Ghislain

Excellent video! Especially the description of sc detect and power loss detect, which are very poorly described in the BTT manual. My only question (besides wishing for a config for Klipper): wouldn’t a momentary push button make more sense than a toggle switch for reset?

Спасибо тебе, друг! Разложил все по полочком, очень подробно, очень понятно! Удачи тебе!

With Klipper?

Thank you for this great tutorial! I do have a question though. If there is a power failure, how can the PW-DET feature work? I mean if there’s no power… how will the mainboard be able to save printing data onto the SD card?

Sehr gut erklärt, hätt ich es nur letzte Woche gesehn. Jetzt ist alles dran und suchte nur nach ein Gehäuse ;)

Thanks for the time you spent doing this awesome video as there's not much information out there on how to get this BTT relay board setup - Looking forward to further educational video!

why is pw detect used?

Thank you very much, excellent video, you saved me hours of research and probably one mother board burned out.

Excellent video, very thoroughly explained! So many people do demos like this but skip over the finer details which are often so important.
Hats off for re-dubbing the video in English, many people would just add subtitles to the original.
Nice enclosure setup too btw 😜
