# The 3D-Printomat clearing method for AutoPrint

# The 3D-Printomat clearing method for AutoPrint

3D-Printomat is an automatic plate-changer for the Bambu Lab A1 series. When a print finishes it pushes the bed off and grabs a fresh plate, so SimplyPrint can keep the queue running unattended. This guide covers what it does, how to select it as your AutoPrint clearing method, and the plate-limit setting it needs.

|| 3D-Printomat runs as a clearing method inside [AutoPrint](https://help.simplyprint.io/en/article/autoprint-put-your-printers-on-autopilot-1hssb9u/), which is part of the Pro plan and up.

## What 3D-Printomat is
3D-Printomat is an auto-ejection plate-changer made by 3D-Printomat for the Bambu Lab A1 series. According to 3D-Printomat, after a print finishes it pushes the current bed off and loads a new plate for the next print, so the printer keeps going without anyone removing the finished part. Paired with AutoPrint, it lets the A1 work through a stack of plates on its own.

## Selecting 3D-Printomat on a printer
You set a clearing method per printer, from the AutoPrint settings.

1. Open the printer's **control panel** and find the **AutoPrint** widget.
2. Open the AutoPrint settings and find the **Clearing method** section.
3. Click the method selector and choose **3D-Printomat**.
4. Set a **Max AutoPrint cycles** value to match your plate stack (see below), then **save**.
5. Flip the **AutoPrint** switch on for the printer.

| You can view the 3D-Printomat clearing gcode under the gcode editor and adjust it if your setup needs it. The default sequence assumes the 3D-Printomat system is installed on your A1.

## Set a max cycle count
3D-Printomat works through a finite stack of plates, so SimplyPrint asks you to set a **Max AutoPrint cycles** value. This is how many prints (plate changes) the printer runs before it stops and waits for you to reload plates. Set it to the number of plates your stack holds, so AutoPrint never tries to load a plate that is not there.

## What SimplyPrint does each cycle
With 3D-Printomat selected, each AutoPrint cycle runs like this:

1. The print finishes and SimplyPrint detects the completed state.
2. The bed cools to the temperature (or for the time) you set, so the part releases from the plate.
3. SimplyPrint runs the 3D-Printomat ejection sequence, pushing off the finished bed and loading a fresh plate.
4. SimplyPrint verifies the bed is clear. With a camera connected, **AI bed check** can confirm visually before continuing.
5. SimplyPrint matches the next queue item and starts it, until the max-cycle count is reached.

For how matching, scheduling and verification work in detail, see the [AutoPrint overview](https://help.simplyprint.io/en/article/autoprint-put-your-printers-on-autopilot-1hssb9u/).
