Check the account, local network permission, Wi-Fi, IP address and access code." url: https://bambubar.app/guides/bambu-studio-not-connecting-printer language: en --- # Bambu Studio not connecting to your printer When Bambu Studio can't see or reach your printer, the cause is almost always the account, the network between the Mac and the printer, or the access code. Here's how to find which. _Updated 2026-11-03_ ## In short Work through these in order: 1. **Cloud mode:** sign in to Bambu Studio with the **same account and region** as the printer; it appears under **My Device**. 2. **LAN Only mode:** the Mac and printer must be on the **same network** (not a guest Wi-Fi); the printer appears under **Other Device**, and you type its **access code**. 3. **On the Mac:** allow Bambu Studio in **System Settings → Privacy & Security → Local Network**, and check your firewall. 4. **On the printer:** check that it's on Wi-Fi with a good signal and shows no network errors; restart it and your router if needed. ## Which problem do you have? - **The printer isn't in the list at all**: start with [the printer isn't listed](#not-listed). - **It's listed but shows "Failed to connect to the printer" or offline**: see [listed but offline](#offline). - **Studio says "Failed to connect to the server"**: see [server errors](#server). - **It worked, then stopped after a change**: see [after a change](#after-a-change). ## The printer isn't listed **In cloud mode** (the printer bound to your Bambu Lab account), Studio lists it under **My Device**: - Sign in to Bambu Studio with the account the printer is bound to, with the same **region** set in Studio's preferences. - Check that the printer is still bound: if someone unbound it in Bambu Handy, bind it again. **In LAN Only mode**, or for a printer that isn't signed in, Studio lists it under **Other Device**, and only when it can hear the printer on the local network: - Put the Mac and the printer on the **same network**. Guest Wi-Fi networks, separate VLANs and some mesh or "client isolation" settings stop devices from seeing each other. - Disconnect from any VPN on the Mac. - Wait a minute: a printer can take 20 to 60 seconds to appear. **On your Mac**, macOS asks the first time whether Bambu Studio may find devices on your local network. If you clicked **Don't Allow**, open **System Settings → Privacy & Security → Local Network** and turn Bambu Studio on. A firewall or security app can also block it. ## Listed but offline, or "Failed to connect to the printer" This message means Studio didn't receive the printer's status within about 30 seconds. 1. On the printer's screen, check that it's connected to Wi-Fi with a reasonable signal, and that it isn't showing a network error. 2. Restart the printer, then your router if other devices are affected too. 3. In LAN Only mode, check the **access code** on the printer's screen and enter it again in Studio. See [finding the access code and IP address](https://bambubar.app/guides/bambu-lab-access-code). 4. Install the latest firmware once the printer is online again. ## "Failed to connect to the server" That's about Bambu Lab's cloud, not the printer: Studio can't reach Bambu's servers. Check the Mac's internet connection, VPN and firewall. In LAN Only mode, the cloud isn't needed to print on your network. ## It stopped after a change - **A factory reset or a new access code:** the code changes. Enter the new one from the printer's screen. - **A new router or Wi-Fi password:** connect the printer to the new network on its screen. - **The printer got a new IP address:** in LAN Only mode, re-add it, and consider a fixed address (a DHCP reservation in your router) so it stays the same. - **You switched LAN Only on or off:** in LAN Only mode the printer moves from **My Device** to **Other Device**, and Bambu Handy stops working until you switch back. See [LAN mode explained](https://bambubar.app/guides/bambu-lab-lan-mode). ## When other apps can't connect either Bambu Bar, OrcaSlicer and Bambu Studio all need the same thing: the Mac and the printer on the same network, with nothing blocking the traffic between them. If the printer is unreachable, no app can fix that, so work through the network checks above first. Once Studio sees the printer again, Bambu Bar can usually set itself up from it: it finds the printer on the network and reads the access code Studio saved. If Bambu Bar alone can't connect, see [Support](https://bambubar.app/support) and [getting started](https://bambubar.app/support/getting-started). ## Questions, answered ### Why does Bambu Studio show my printer as offline when it's printing? Studio isn't receiving the printer's status. Usually the Mac and printer aren't on the same network, the printer's Wi-Fi signal is weak, or the account or access code no longer matches. Restarting the printer and Studio fixes a stuck connection. ### Where is the access code? On the printer's screen, in its network settings. See [finding the access code and IP address](https://bambubar.app/guides/bambu-lab-access-code) for your model. ### Why is my printer under Other Device instead of My Device? **My Device** lists printers bound to the Bambu Lab account you're signed in with. A printer in **LAN Only** mode, or bound to another account, appears under **Other Device**, where you connect with its access code. ### Does Bambu Studio need internet access? Only in cloud mode. In LAN Only mode, Studio sends prints and monitors the printer entirely on your local network. ## Read next - [Access code and IP address](https://bambubar.app/guides/bambu-lab-access-code): Where your printer shows its 8-character access code and its IP address, and how to use them to connect from your Mac. - [LAN mode explained](https://bambubar.app/guides/bambu-lab-lan-mode): Cloud mode, LAN Only, LAN Only Liveview and Developer Mode: four different settings, and which ones you actually need. - [Bambu Studio on a Mac](https://bambubar.app/guides/bambu-studio-mac): Where to download Bambu Studio for Mac, how to connect your printer, and how to follow prints without keeping it open. - [Support: Setup, Camera and Connection Help](https://bambubar.app/support): Set up Bambu Bar and fix printer discovery, camera, controls and widget problems, or get help with your supporter license and purchase account. --- Bambu Bar is an independent app, not affiliated with or endorsed by Bambu Lab.
