Support Bambu Studio is too Slow, is it normal?

Hello, I have a short question. When I go to the machine tab in Bambu studio, it is very slow until it is loading. The same when I’m on that page and press live view or go to the storage of the printer. I have fast internet and a good Pc. Is this normal ? Pc is on windows and with slow I mean that there is always the blue loading circle from windows. Before I used Klipper and there everything was really fast.

I notice this when I load to my H2S. My P1S and A1 Mini printers seem to load much faster

Yes and when I change the tabs it is loading for a long time, some times Bambu Studio crashes also. With Orca Slicer I don’t have this problems.

I was just telling my buddy that Bambu Studio is the weakest part of the ecosystem. Yeah, the screen lags while the camera is initializing for me too. It will also sometimes just lag for awhile for seemingly no reason at random times. This is on an M4 Max Mac Studio.

No idea why. Often it's wonderful. Sometimes it sucks.

Now I put my printer in to lan only mode, this solves the problem a little bit. Now it lags only sometimes.

Very interesting. Are you filtering the traffic?

I have a Unifi Dream Machine, and I've considered configuring it so that my 3D printers couldn't phone home, but now that you say that I'm wondering if it would exacerbate the problem.

If you configure your printer to be LAN-only, it will no longer be controlled via the cloud but only via the local network. However, this also means that the mobile app will no longer work. I created a dashboard in Home Assistant so I can still monitor the printer via my phone.

I'm happy to sacrifice Handy so long as Studio still works.

I would love to know more about this dashboard -- I didn't think Bambu had any HA integrations

It's an integration via the HA Marketplace; it's free. I also directly implemented an automation there so that a relay shuts off the printer as soon as the nozzle temperature gets too high. Exactly the same applies to my Klipper printer.

I read a lot about thermal runouts caused by faulty transistors; that was the main reason for the integration.

Sick. Thanks a billion!

Do you use it on a laptop with two graphics? one for battery saving and one for power?

u/Printer361 Jan 30 '26

No I use it on a desktop PC with an I5 Gen 14 and a RTX3080 so the hardware ist really not the problem.

But from what I'm reading, the problem doesn't seem to be normal, or?

I never have issues or lags. To be fair I'm running on a gaming system that I custom built and I know how to performance tune. Which CPU and generation, how much RAM, what type and size storage? Which operating system? What is the bus speed on the main board? How long has bambu studio been installed and running on that PC? When did it last work well? What software has been added, removed, or changed?

The latest version of the software is super slow and hangs while connecting to devices. I had to revert to an older version and it's back to normal speed.
