## Connect the Sunlu S9 Plus to SimplyPrint

| Way of connecting | Status | What you need | Notes |
| :--- | :--- | :--- | :--- |
| SimplyPrint | Expected to work |  | Through OctoPrint |
| OctoPrint (Directly, over USB) | Expected to work | A Raspberry Pi running OctoPrint, plugged into the printer with a USB cable | Ships with a USB cable for direct PC printing and Marlin firmware; serial printing like the S8. ([Source](https://the-gadgeteer.com/2022/09/01/sunlu-s9-plus-3d-printer-review-powerful-3d-printing-with-oodles-of-options)); Expected to work like the Sunlu S8 |
| Klipper (Moonraker) | Not compatible |  | Ships Marlin; community Klipper configs exist, after you install it. ([Source](https://github.com/weeksrw/Sunlu-S9-Plus-with-Dryer-Box-on-Klipper)); Doesn't ship with Klipper: it runs Klipper after you install it in place of its own firmware, a modification |

### What works with SimplyPrint

Connected through OctoPrint, SimplyPrint is expected to support everything the Sunlu S9 Plus lets other software do: the camera and AI failure detection, remote printing, temperature and movement control and AutoPrint. 3 features depend on how it's set up: the table says what each needs.

## What slicer to use for the Sunlu S9 Plus

None of the slicers in SimplyPrint's cloud has a ready-made profile for the Sunlu S9 Plus, but it takes standard G-code: start from a similar printer's profile and set the bed size, height and nozzle to match.

We only list slicers you can use in the SimplyPrint cloud, so there may be others for the Sunlu S9 Plus.

## The app for the Sunlu S9 Plus

Sunlu doesn't make an app for the Sunlu S9 Plus. SimplyPrint works as its app: on your phone and in any browser, with a slicer in the cloud.

- An app for iPhone and Android, the same in any browser, and a slicer in the cloud.
- More than monitoring: a print queue, AI failure detection, AutoPrint and accounts for a team.
- Printers from many brands in one place, side by side.
- Hosted in Frankfurt, Germany, under the GDPR.

## Automate the Sunlu S9 Plus

**Bed slingers are the easiest to automate.** The Sunlu S9 Plus moves its bed back and forth, so its plate comes out to the front of the printer. That's what plate swappers like these use: they take the finished plate off and slide a fresh one on. Without a kit, a G-code routine can push cooled prints off with the toolhead. For example: [JobOx](https://simplyprint.io/features/autoprint/jobox), [swapmod](https://simplyprint.io/features/autoprint/swapmod).

### Ways to automate it

- [Push prints off with the toolhead](https://simplyprint.io/features/autoprint/push-off): On a bed slinger, a G-code routine can sweep the cooled print off the bed before the next job starts.
- [Your own ejection G-code](https://simplyprint.io/features/autoprint/custom): Write the routine that clears your plate, and AutoPrint runs it after every print.
- [A robot arm, or anything with an API](https://simplyprint.io/features/autoprint/api): Tell SimplyPrint the plate is clear through the API or a webhook, from a robot arm or your own system.
- [Clear it by hand, keep the queue](https://simplyprint.io/features/autoprint/manual-mode): AutoPrint waits for you to mark the plate clear, then starts the next job.

[How AutoPrint works](https://simplyprint.io/features/autoprint). AutoPrint comes with the Pro plan and up.

## What filament can the Sunlu S9 Plus print?

Filament compatibility for the Sunlu S9 Plus: the materials it can handle, judged from its hotend, bed, chamber and enclosure.

| Filament | Suitability | Notes |
| :--- | :--- | :--- |
| PLA | Great | The easiest filament to print. Works on almost any printer; a heated bed helps adhesion but is not required. |
| PETG | Great | Comfortably in range (PETG likes a ~230-250C hotend and a ~70-85C bed). |
| TPU & flexibles | With care | Possible, but a Bowden extruder makes flexibles harder - print slowly and prefer firmer (higher-shore) TPU. |
| ABS & ASA | With care | The bed is hot enough, but ABS and ASA warp without an enclosure, which is strongly recommended for clean prints. |
| Nylon (PA) | With care | Possible with care - an enclosure and very dry filament are essential. |
| Polycarbonate (PC) | Not ideal | Not recommended - PC needs very high hotend temps and an enclosed chamber. |
| Carbon-fiber & glass-filled | With care | Possible if you fit a hardened or wear-resistant nozzle - the abrasive fibers quickly wear a stock brass nozzle. |
