P1S never downloads from studio. Will from handy

Hi folks

I’ve had my p1s for about a month. I was able to send a couple of prints directly from studio to the printer in the first week or so of usage.

Since then though Ive had no luck and have just been manually copying to the SD card.

I’ve had some time to investigate since but I can’t find any solutions.

Using latest version of studio (released a few days ago) and latest firmware (released a few days ago).

I have changed SD cards.

I slice my file in studio. I can connect to my printer. I can see all my settings, AMS, camera. It’s at about half signal strength but I have no issues connecting.

I upload to cloud no problem.

I cut across to the printer, downloading 0% and it never advances. The printer starts heating it’s bed. It never progresses and never starts.

I can however print directly from handy and it just works. Printer downloads at a reasonable pace and prints work.

I’m stumped. I have some big multi plate jobs I really want to get started on and don’t want to have to be copying files manually anymore. I want to take advantage of the bambu software but it just won’t let me at the moment.

Open to all suggestions.

Hi

That’s a very odd issue.

I didnt understand the statements above. Correct me and let me know where you got stuck in the following order of events:

  1. You slice the file.
  2. Then you go to the top right corner and select print (or send?), correct?
  3. It will pop up a new window with the info and show a “send” button at the bottom right corner.
  4. You press it, and what happens? You should only be able to move to the printer tab after uploading to the printer.

Yes that’s correct.

It uploads the file to the cloud successfully.
It takes me to the printer tab and shows that it is downloading (0%)

I can see from the printer stats on the top right of the screen that the bed starts heating. But the print never downloads or starts.

It’s now also doing the same thing from Bambu handy when it was working fine yesterday…

I even did a factory reset. Rebound it to my phone and still not working. :confused:


And here from studio

Unplug power for 30 seconds and plug back in. Easy first troubleshooting tip, especially for something strange like this. It’s almost like their is an issue with WiFi and a reboot isn’t the same as actually power cycling it.

In either the Handy app or Bambu Studio do you have multiple printers. Click the Shed P1S icon above Status in the pic above to verify. If you do a factory reset I believe you have to rename the printer or add it back. If it has the same name there could be duplicates. Also check the drop down list under Prepare in Bambu Studios for duplicate printers.

It also looks like the bed heats but thermistor temperature stays at zero although the bed always heats before the nozzle anyways so that might just be normal behaviour but manually loading or unloading filaments should rule that out as an issue.

Lastly check the WiFi antenna to make sure it didn’t come lose as the WiFi sucks even with the antenna. Especially if printing via SD card still works.

Force stop Handy app and clear cache if using Android, not sure what the iOS equivalent is although this wouldn’t explain the Bambu Studio issues.

Can you manually load and unload filaments?

Well. I cleared the cache and user data on handy. Repaired to the printer without doing a factory reset and changed the name on the app when I added it back.

It was able to print from mobile again…

I guess I’ll try studio once this print is done in a half hour…

I’m not too sure what you mean by being able to load the filament sorry. The AMS picks it up and I’ve done multi colour prints (from SD card at least) without issues.

Well…at least i get an error now. Showed 0%, shows the new printer name. Same result but with an error now at least. Im also getting full wifi signal quality now as well.

If it wasnt going through the cloud i would assume something between the connection of my PC to the printer…but that cant be the case if its uploading it to the cloud. How is it any different from the printer if its invoke via the app or studio when in both instances it has to download the project from the cloud? It makes absolutely no sense…

I found the network tester, Test Storage and Test Storage upgrade have both failed…whatever those are but to me that would seem to be referencing the SD card…i’ve tried a 3rd SD card by the way as well, Sandisk and Toshiba…

No, it has internal storage, if it didn’t you wouldn’t be able to print anything without an SD card in it which I have done many times so it doesn’t download to the SD card. Why it works through the Handy app and not Bambu Studio’s doesn’t make sense but that error code matches their wiki. I don’t know what network tester that is so I can’t comment on the responses, I would ping the IP address to see the latency and if any packets were dropped but that is just me. It really sounds like a network issue on the P1S but since Handy works, it’s just really, really odd.

I am 90 percent sure to use Handy you have to use Bambu Cloud because your phone isn’t slicing the file, it’s sent to Bambu cloud, then sliced, then sent to your printer. LAN only mode would fix the Orca/Bambu slicer issue (or should) but then Handy wouldn’t work.

Unless anyone else has any ideas I would contact support It sounds like sending locally worked for a week only which isn’t good for a new printer, issues like this tend to get worse over time, not better.

Thanks mate.

That’s actually the network tester within studio, which produces its own log.

I’ve created a support ticket with everything and sent it through to them. Hopefully we can get it sorted. I’ll be sure to update the thread if / when it is fixed…

Only other thing I can think of is ports being blocked on your router is it has a firewall enabled but the Handy app still works. Seems network related, unless you’re blocking AWS then I’m pretty sure you should be good. Suggestions are to statically IP or create a DHCO IP reservation for your P1S but I doubt that would help. Especially if you can send prints from outside your LAN (like over cell data) or view the camera remotely.

Can’t believe the hey are still using FTP, granted that’s in LAN only mode. Really need an Ethernet port on these things. Would tell you a lot more as the WiFi/download speeds on the P1 are terrible, people have been complaining about that since they came out.

Test Storage and Test Storage upgrade have both failed

, error (printer isnt connected currently)
what error msg you getting ? i assumed these were actually something to do with the sdcard, but these appear to of changed or moved

Yes, that test just seems worthless, both those are http urls, if you go to them in a browser you get a 404, the public url’s simply don’t exist. The ones that do work are just “success” pages except test.plugin download which actually downloads the files for the plug in needed for printing via cloud. They also look like real url’s.

Going to URL produced by Test BambuLab

Not sure what the point of having bing.com in there is and for some reason it’s http also (redirects to https). Honesty, I am thinking of moving to LAN mode. Handy app is nice but all this cloud stuff is overkill when it’s mainly sending a file to AWS, slicing it, then sending it to your printer. Would be easier if you could leave Bambu Studio open in the background, have Handy send the file there to slice and send to your printer without leaving your LAN. I am not a fan of sending all my MQTT data to the cloud when there is zero reason to.

Also, apparently Orca slicer uses the same plugin that Bambu does for it’s printers so it’s not the slicer either. I don’t think it’s a network issue, something else is going on. It does makes sense as Orca would have to write their own plugin to send to Bambu and Orca is a fork of Bambu also, which is a fork or Prusa slicer. According to centralops, both those domains are available for registration.

About the only solution I saw for this issue was unplugging the power and plugging it back in… Although it never seems to actually start the download in this scenario, it just sits at 0%. Similar issue, uploads to cloud fine, printer just won’t download and print. Recently Bambu has been complaining about AWS costs when they literally set it up to work this way. Like making the Panda Touch just “quit” working because it makes calls to AWS. The only error is that 0500-400b one above which is a general networking error.

did you post domain available for registration ?

Lan mode will be the next test. I’ve held off because I really like being able to check on progress from the app when I’m in bed or whatever. Hell the whole software eco system and it all 'just working ’ is why I pulled the trigger after 8 years messing around and tinkering with inferior printers.

Same problem with Studio. Any solution?

Not yet sorry. Still waiting on a response for my support ticket.

Have you tried checking if there might be any firewall settings on your computer or router that could be affecting the communication between Studio and your printer? Sometimes those settings can sneakily cause download hiccups. Also, since you mentioned it prints fine from Handy, it could be worth double-checking the settings in Studio to ensure everything’s aligned for your multi-plate jobs.

I found that it was the SD-card that was somehow making mine stop.
Calibrations, resetting the machine itself, nothing worked. but somehow I could remote to the printer. Change the name, send the calibration requests etc.

I took out the SD-card, wiped it, and replaced it. Now I am back to normal printing.
Not sure if I got lucky or not?
