This guide covers what you see when you open a printer in the app, what each control does, and what to do when something looks off. || The app and the web panel share one source of truth. Whatever you can see and do on simplyprint.io for a print job, you can see and do on the phone. ## Table of contents - Open a printer - The live camera tile - Temperatures - Progress, ETA, and current layer - Pause, resume, cancel - Clearing the bed - Multi-printer view - AI overlay during a print - Watching across multiple printers (Pro+) - What needs the web panel - Connection requirements - Troubleshooting the camera - Related articles ## Open a printer On the app's home screen, every printer your account has access to is listed. Tap a printer to open its detail screen. The list shows live status badges, so a quick glance tells you which printers are idle, printing, paused, errored, or offline. Tap once to drill in. | Group your printers in the web panel (Printers > Groups) and the same grouping shows up in the app. On a print farm or school lab with a lot of machines, this is how you avoid scrolling through dozens of cards. ## The live camera tile If the printer has a camera connected through the SimplyPrint bridge (Rasperry Pi / OctoPrint / Klipper / etc.), the camera tile shows a live MJPEG-style stream of the bed. - **Tap to zoom**: pinch in and out on the camera tile. - **Rotate to landscape**: full-screen camera view, useful for inspecting a layer. - **Tap the fullscreen icon**: enlarges the camera to fill the screen with the controls overlaid. The stream rate matches your plan's stream speed. Free has a slower refresh; paid plans get a smoother feed. ## Temperatures Below or beside the camera, the app shows live temperatures for: - Hotend (nozzle) - current and target - Bed - current and target - Chamber (if your printer reports it) The values update in real time from the printer's firmware via the bridge. Tap a temperature to see a small chart of the last few minutes if your printer supports it. ## Progress, ETA, and current layer The progress section shows: - Print job file name - Percentage complete - Time elapsed and time remaining (ETA) - Current layer / total layers (if the file reports it) - Filament used so far ETA is computed from the slicer's estimate plus the live print rate, so it gets more accurate as the print progresses. ## Pause, resume, cancel The control row right below the camera has three primary buttons: - **Pause** - sends the firmware pause command. Movement stops, temperatures hold, the nozzle parks (printer-dependent). - **Resume** - resumes a paused job. The nozzle returns to the print and continues from where it stopped. - **Cancel** - ends the job immediately. Use this when you've seen a failure that won't recover. Cancel asks for confirmation before firing. Pause and resume are single-tap. ||| Cancelling is final. The job cannot be resumed once cancelled - you'd need to restart from the queue or the file. ## Clearing the bed After a print finishes, the bed needs to be cleared before the next job can start. The app has a **Clear bed** button that: 1. Marks the previous job as completed in the system. 2. Optionally moves the printer to a homing position. 3. Frees the printer to receive the next job from the queue. For [AutoPrint](https://help.simplyprint.io/en/category/about-3d-printers-bssj1b/) hardware (the conveyor / belt / arm models), clearing the bed is automatic; the button is hidden in those cases. ## Multi-printer view If you have multiple printers, the home screen is your control tower. Each card shows a thumbnail, current job, progress, and status badge. Tap a card to drill in, or use the filter / sort controls at the top to narrow the list. On Pro and above, **multi-stream** lets you watch several cameras at once in a grid. This is mostly a web-panel feature, but the app's printer list with thumbnail previews is the mobile equivalent. ## AI overlay during a print If AI Failure Detection is running on the print, the camera tile shows a translucent overlay marking where the model thinks there's a problem. The confidence gauge shows how sure the model is. If the model crosses the alert threshold, the app sends a push (see [Push notifications from SimplyPrint to your phone](https://help.simplyprint.io/en/article/push-notifications-from-simplyprint-to-your-phone-1lma1ad/)) with a snapshot of the camera and a one-tap Pause button right in the notification. AI Failure Detection runs minutes against your account's monthly AI quota. See [The SimplyPrint AI Failure Detection feature](https://help.simplyprint.io/en/article/the-simplyprint-ai-failure-detection-feature-1blpac7/) for how the quota works. ## Watching across multiple printers (Pro+) On Pro and above, SimplyPrint includes multi-stream tiles and multi-printer controls (multi-pause, multi-resume, multi-cancel, multi-clear-bed). The phone app surfaces these as bulk actions when you select more than one printer from the list. Free and Basic plans see one printer at a time without bulk actions; the per-printer controls are the same. ## What needs the web panel A few things are still web-only: - Slicing files in the cloud slicer - Editing per-printer settings (camera URL, gcode hooks, firmware-specific options) - Building the print queue from scratch - Setting up a new printer The app intentionally doesn't try to be a full panel - it's the monitor-and-control surface. ## Connection requirements Live cameras need: - A camera physically connected to the printer's bridge (Pi / OctoPrint / Klipper / SimplyPrint-OS / etc.) - The bridge online and communicating with the SimplyPrint cloud - Your phone has internet If the camera tile shows "No stream" or a still image, the camera is either not connected, configured to a different URL, or the bridge is offline. Confirm the bridge status in the web panel first. ## Troubleshooting the camera - **No camera at all**: the printer doesn't have one connected via the bridge. Add one to the bridge first. - **Black screen / spinner**: the bridge is online but the stream URL isn't reaching the cloud. See [Klipper webcam not detected](https://help.simplyprint.io/en/article/klipper-webcam-not-detected-1q7uw5y/) for Klipper-specific fixes. - **Frozen frame**: the stream stalled. Pull-to-refresh the printer screen. - **Stream is choppy**: the printer's network is slow. The stream is uncompressed-ish MJPEG; weak Wi-Fi will struggle. - **The bed is on the camera but I can't tap Pause**: the printer is connected but not currently printing - Pause only works during an active job. If everything looks right in the app but wrong on the printer side, open the printer in the web panel; the same diagnostics will be there with more detail. ## Related articles - [SimplyPrint on your phone: the mobile app](https://help.simplyprint.io/en/article/simplyprint-on-your-phone-the-mobile-app-vfelp5/) - [Download and sign in to the SimplyPrint app](https://help.simplyprint.io/en/article/download-and-sign-in-to-the-simplyprint-app-1y49y3a/) - [Push notifications from SimplyPrint to your phone](https://help.simplyprint.io/en/article/push-notifications-from-simplyprint-to-your-phone-1lma1ad/) - [Approving queue items from the app](https://help.simplyprint.io/en/article/approving-queue-items-from-the-simplyprint-app-vzxaag/) - [The SimplyPrint AI Failure Detection feature](https://help.simplyprint.io/en/article/the-simplyprint-ai-failure-detection-feature-1blpac7/) - [Optimal camera setup and lighting for best AI failure detection results](https://help.simplyprint.io/en/article/optimal-camera-setup-and-lighting-for-best-ai-failure-detection-results-1eo262r/)
