Power button should turn machine off and on

[user_1793830463]

You are a champ. Your response truly serves the discussion here. It serves the discussion around that power button, AND the discussion around climate change.
The world could not do without you.

Well, YOU brought it up didn’t you?
I like the sarcasm in your response, i hope you liked mine too…

Has anyone else felt the power button should be puttin the machine to some sort of sleep mode?

I’m quite happy with it just turning the display off. It would be too easy to accidentally power the machine off while printing if it was any different.

Most of the circuitry goes to sleep after 10 minutes or so of idling, and then it draws about 3W of standby power. That’s perfectly fine to me. If I want the machine more powered off than that, I use the hardware power switch at the back or a remote HA switch I also have in place.

also, with that choice of “power” icon, I’m pretty sure if you look 100 people who have never seen a 3D printer before, showed them the Bambu Lab printer, and asked them what they thought that button did, almost every one would surly take one look at the icon and say they thought it would switch it off…

Count me as one of those 100 people. I’d say it’s the mismatch between icon and behavior that’s the root of the confusion. The whole point of using icons is so that it’s intuitive and you don’t have to read a manual to figure out what a particular button does.

New user here. Sweet bejesus, I had to google this because I was sure my power button is faulty. Now, I figured out that I have to turn off the enclosure light manually but “Bambu Lab” light of the extruder is still glowing.

It’s not a big deal to hug the printer and give the PSU switch a nudge but I too assumed that power button in the front is an actual power button. And so it should be.

While we are complaining about poorly implemented buttons…

The other top button is marked with the symbol that is the standard for an EMERGENCY STOP. As such, it should immediately cancel or at least pause all current operations. Instead, it asks for verification, which has to be provided on the screen, or app, or in Studio. If I’m dealing with an emergency, my attention should be on the problem, not searching elsewhere so I can repeat my command.

Old topic, but I wanted to mention that the X1Plus firmware permits some changes in button usage.

The firmware distinguishes between short and long button presses, providing four functions from the two buttons. So now we can finally choose a true emergency stop, using our choice of a long or short button press.

Well in my case because the machine consumes a measured 23 watts in standby. Yes, it’s not a lot, but it’s wasted power. I was really expecting the front ON/OFF switch to do more than turn off the LCD backlight.

I confirmed this by setting the hotend to 100degc and bed to 40degc, internal led light on. Waited a while and then used the front ON/OFF to turn the machine off. Surprise, surprise, the LCD goes blank but the hotend and bed continue to be heated, the lighting stays on.

Surely as a minimum, the front on/off switch should turn everything off and go to the 23watt standby value. How hard can this be to program? Come on Bambu. Other than that I am a new user and am delighted with the machine. Now I know what a first layer should look like

I fully agree.
Climate change has nothing to do with turning any electrically powered machine or appliance anyway.
Climate change is a naturally occurring phenomenon that happens periodically around every 525 years and what we mere humans do or how much Co2 gas we produce has nothing to do with it.

Did I read somewhere that the latest X1Plus can now designate the front/top buttons to run g-code? If so, could a series of g-codes be coded in order to shut everything down and get to some kind of sudo standby (off).

[MZip]

Just a guess but for mechanical things with motion I’d bet one button was to be an emergency stop and the other was a soft power button. The power supply they are using doesn’t have soft power control though. I’d bet it was a design change for some reason that didn’t get fully changed out. Maybe they had some pallets of buttons already molded?

Who knows? But using symbols that imply other uses sounds like a design change to me for some reason.

Did I read somewhere that the latest X1Plus can now designate the front/top buttons to run g-code?

I don’t think that running g-code from the buttons is currently possible. I’ve not heard of using the buttons for anything other than the four functions posted above. Sleep/wake the screen, Reboot, Pause the print, Abort the print.

There might be some use for starting g-code with a button press, but I think it could be dangerous if a button is pressed accidentally.

I also don’t have a need for another standby method. Bed heating stops after a print completes and the fans stop after cool down. Just turn off the chamber light before starting a print and it will stay off until a print begins. When the print completes the light will go back off. There is already automatic screen shutdown with a user-selectable delay. It’s been a while since I had a Kill-o-watt connected to my printer, but I think standby mode only uses about 8 or 9 watts.

[GrahamGo]

Thanks, you are right. It’s not mentioned as a new feature in the latest version. It must have been someone requesting it or something. I measured the standby to be 23 watts on my X1 using a fluke meter measuring the current in one of the power lines (230vac). I’m too afraid to try X1plus due to my concern about loosing warranty. So the rear switch is my goto place

I found this thread because I was googling why the big, obvious on/off button on the front of my new printer wasn’t turning it off. I thought I had a bug because, like OP, I assumed the symbol used for a power button on every other electronic device was a power button.
