Migrating from the SimplyPrint Bambu Lab client to the new SimplyPrint Client

Migrating from the SimplyPrint Bambu Lab client to the new SimplyPrint Client


This guide is for you if you still run the old SimplyPrint Bambu Lab client. The new SimplyPrint Client replaces it: one app for Bambu Lab and every other brand SimplyPrint connects through a bridge. Switching takes three steps, and you keep your printers and their history in SimplyPrint.


Not sure which one you have? Open the client and look at its version. 1.0.0-beta followed by a number (for example 1.0.0-beta.117) is the old Bambu Lab client. 1.0.0-rc followed by a number is already the new SimplyPrint Client.


What this guide covers


Why switch

  • Updates. The old Bambu Lab client hasn't been updated in a long time. The new Client gets fixes and new printer support every few weeks.
  • New features, such as switching the chamber light on and off and setting each fan from SimplyPrint, and a Diagnose button that tells you why a printer is offline.
  • More printers. One Client connects Bambu Lab, Creality, Anycubic, Elegoo, Snapmaker, Ultimaker and Duet printers, and Flashforge, Prusa, Dremel and Klipper printers in beta.


Switching isn't required yet, and the old client keeps working. There is no automatic upgrade from the old client for now, so you switch by hand with the steps below.


You can switch while printers are printing. The prints run on the printers, so they keep going. Only a print that finishes during the switch may not get its result recorded in SimplyPrint.


Step 1: stop and uninstall the old client

Do this first. If the old client is still running, it keeps the connection to your printers and blocks port 8000, and the new Client can't take over.


Don't delete the configuration folder (.config/SimplyPrint on Linux, AppData\Local\SimplyPrint on Windows, ~/Library/Application Support/SimplyPrint on a Mac). On the same computer, the new Client can pick your printers up from it.


Windows

  1. Close the old client. To be sure it's gone, open Task Manager (Ctrl + Shift + Esc) and end every SimplyPrint process.
  2. In the Start menu, find SimplyPrint Bambu Lab, right-click it and choose Uninstall. Follow the uninstaller.


Check: http://localhost:8000 no longer opens the old client.


Linux

  1. Open a terminal on the machine (or connect over SSH).
  2. Run sudo systemctl disable --now simplyprint-bambu-lab.
  3. Remove the old program and service: sudo rm -rf /opt/simplyprint-bambu-lab, then sudo rm /etc/systemd/system/simplyprint-bambu-lab.service, then sudo systemctl daemon-reload.


Check: systemctl status simplyprint-bambu-lab reports that the unit could not be found.


Raspberry Pi with SSH

Follow the Linux steps above over SSH. Then install the new Client with the Linux method in step 2 - you don't need to reflash the card.


Raspberry Pi without SSH

See Raspberry Pi without SSH below.


Mac

  1. Open Terminal.
  2. Run launchctl unload ~/Library/LaunchAgents/com.simplyprint.bambulab.plist, then rm ~/Library/LaunchAgents/com.simplyprint.bambulab.plist, so it doesn't start again at login.
  3. Delete the simplyprint-bambu-lab folder from your Applications folder.


Check: the old menu bar icon is gone, and http://localhost:8000 no longer opens the old client.


Step 2: install the new SimplyPrint Client

Follow How to install the SimplyPrint Client, or the setup guide. On a Raspberry Pi image, pick SimplyPrint Client OS, not SimplyPrint Bambu Lab Client OS.


Check: the new Client opens at http://localhost:8000 (or http://<device-ip>:8000), and Settings > About shows a version starting with 1.0.0-rc.


On the same computer, your Bambu Lab printers usually show up in the new Client by themselves, because it reads the old client's configuration. If they are there and online in SimplyPrint, you are done.


If a printer is missing, add it again and link it to the printer you already have in SimplyPrint:

  1. In the new Client, click Add printer > Bambu Lab and add the printer.
  2. On its card, click Set up in SimplyPrint.
  3. In SimplyPrint, choose Link to existing and pick the printer.


Check: the printer is online in SimplyPrint with its old name and print history.


Don't delete your printers in SimplyPrint and add them as new ones. Linking keeps their name, print history, costs and maintenance records.

Raspberry Pi without SSH

Without SSH you can't uninstall the old client or copy its files, so start fresh. It takes about 10 minutes, and nothing in SimplyPrint is lost.


  1. Flash the card with SimplyPrint Client OS, as in How to install the SimplyPrint Client. This removes the old client.
  2. Open the new Client and add your printers again. You need each Bambu Lab printer's IP address, access code and serial number, which the printer's screen shows.
  3. Link each printer to its existing printer in SimplyPrint, as in step 3.


Check: every printer is online in SimplyPrint with its old name and history.


Have SSH after all, or another way to reach the old Pi's files? You can copy the configuration instead. See Bambu Lab: Migrating configuration from one device to another.


The new Client keeps spinning or opens on port 8001

Both mean the old client is still running. It holds port 8000, so the new Client moves to 8001, and both try to connect to the same printers.


  1. Go back to step 1 and remove the old client completely.
  2. Restart the computer or Raspberry Pi.


Check: the new Client opens on port 8000 and your printers come online.
