My new P1S will not bind to my WIFI. Help!

My new P1S came today and it prints just fine with the preinstalled files. But I cannot figure out how to get it to sniff out my WIFI and bind with it. I got an A1 mini a few weeks ago and didn’t have any trouble getting it to bind. When I scan the QR image on the P1S, it sends me to Chrome and opens my Bambu Handy app. It tells me “This site is trying to open another application”. It gives me the choice of Allow or Don’t allow. I’ve tried it both ways. After that, it takes me to a screen asking me to accept terms and conditions which I accept, and then I press Confirm to Bind. After that it just freezes on a screen that says “Building Connection” and I see a “spinner”. It also says “If the printer’s Bluetooth pairing request appears, please double confirm on both phone and printer (click “Pair”)”. But, the spinner just keeps spinning while I’m standing in front of the printer. I remember when I setup the mini, it gave me a choice of Bluetooth vs WIFI. I took the WIFI and it easily connected or bound to it. And that’s what I want, WIFI, not Bluetooth. From this point, I’m stuck at this screen. I’ve gone through the steps repeatedly, re-scanning the QR image, but I always end up back here. Any help will be appreciated. PS: I control my A1 Mini remotely from my PC in another room using Bambu Studio.

I am having the same problem. Nothing I have tried is working.

You may try entering your wifi credentials on the SD card

Sorry for your trouble, but I’m glad I’m not alone. Maybe someone will help us. So far, Bambu Lab factory support seems very inaccessible. I think they hope we’ll figure out our own problems with forums like this. In fact, I think almost all manufacturers are doing this. I’ve tried to connect with Live Chat several times but can’t get past the questionnaire.

I’ll see if I’m smart enough to do that. Thanks.

philch suggested using the wiki to configure my wifi directly to my sd card. He gave me a link to the wiki, a link dealing with this particular issue (Thanks philch!).

The wiki gives instructions to download a file and they supply you with a link for doing that. When I click on the link, a file goes to my download folder and Chrome alerts me that it’s a dangerous file. When I click on it, despite the warning, it doesn’t open for me.

The name of the file is 438657.crdownload. Wiki describes this as the user_wifi.cfg file. Wiki further instructs me to substitue my wifi name and password with the config file’s examples. Without being able to open the file, I cannot make any substitutions.

Do you think Chrome corrupted the file for my protection, that it would open otherwise?

Wifi further tells me to plant this file into the root directory of my sd card. When I put the sd card in my computer it shows me 8 folders, none of them are named root. If I dump the file outside of any folders, it still won’t open for any editing.

My next experiment was this: I opened my sd card on my pc. I right clicked outside the folder and used notepad to make a blank text file. I renamed the file “user_wifi.cfg” (without the quotes). Microsoft advised me that changing the name to end with .cfg instead of txt might render the file useless. But I did it anyhow. It wouldn’t open by double clicking on it, so I right clicked and chose “open with” and named notepad as the app to open it. Then, I typed in my network and password as suggested by the wiki. With my printer turned off, I replaced the sd card and turned the printer back on. When I scrolled through the screens, my network was there. Shazam! I’ll edit this post if I’m able to find my printer in Bambu Studio.

I was able to download it, and then I used McAfee to scan it, and it was clean. I followed the directions too, and the network appeared on my printer. However, it doesn’t show up in bambu studio, even when i am on the same LAN. It doesn’t bind in the handy app, either.

The number and .crdownload extension is just a temporary filename that Chrome uses until the download is complete. Your download was not completed, even if it showed 100% done.

Is this your only printer? Were you using the studio successfully with other printers?

Yes, this is is my only printer. I got it last week, and am trying to connect it now.

I think it has to be 2.4GHz wifi band, not even shared with 5GHz,

So I just got the printer bound to the network. What I ended up doing was making a separate guest network specifically for my printer, and enabled MAC Address Filtering. I input the MAC of my phone, computer and printer into the filter, then I restarted my phone, printer and wifi router. I then went through the binding process again, and my printer bound successfully. Hope this helps!

Well, I’m glad you knew how to do all that because that’s all Greek to me :slight_smile:

I had the same issue. Make sure that you “forget device” for the printer in the list of known bluetooth devices. Turn bluetooth off/on or restart your phone. Then you should be good to try again.

Hello, I have the simmilar issue… My pc cant connect to my p1s and so I followed the troubleshoot and logout of the devices but now I cant even login im getting “error code 83968037” on printer when im trying to login and “error code 1 context deadline exceeded” on my babmu lab app on pc… So I tried to open a support ticket but cant even do that im getting “Gateway time-out Error code 504” on the website… Any1 know how to fix it or how can I get in touch with the team?

Bambu labs is having an outage including printer binding

So, what the hell does that mean?


Just what it says, partial outage on several services. Meaning those services may/may not function for you.

It appears cleared up now though

Am I correct in assuming that would have nothing to do with my offline (no-cloud) printing?
