The 3DQue Ejection Kit clearing method for AutoPrint

The 3DQue Ejection Kit clears finished prints off the bed using the print head, so SimplyPrint can start the next print on its own. According to 3DQue it works on a range of Cartesian printers, and it has no plate stack to refill. This guide covers what it does, how to select it as your AutoPrint clearing method, and how it relates to the built-in push-off method.

What the 3DQue Ejection Kit is

The 3DQue Ejection Kit is a hardware kit by 3DQue that auto-ejects prints using the toolhead. After a print finishes and the bed cools, the print head sweeps across the bed to push the part off the front edge, clearing it for the next job. 3DQue states it supports a variety of Cartesian printers; check 3DQue's site for the current list of supported printers.

Because it clears the bed in place rather than swapping plates, the 3DQue Ejection Kit can run continuously for as long as there is matching work in the queue.

How this compares to the built-in push-off method

The 3DQue Ejection Kit uses the same idea as the standard print-head push-off method built into SimplyPrint: the toolhead sweeps the part off the bed. In fact the clearing gcode for the two is the same starting template in SimplyPrint. The difference is the hardware: 3DQue describes the kit as purpose-built to make push-off reliable on the printers it supports. If you have the 3DQue kit installed, pick this method; if you are pushing off with a bare printer, the standard push-off method is the one to choose.

Selecting the 3DQue Ejection Kit 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 3DQue Ejection Kit.
4. Save, then flip the AutoPrint switch on for the printer.

What SimplyPrint does each cycle

With the 3DQue Ejection Kit 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 more easily.
3. SimplyPrint runs the push-off clearing sequence, sweeping the part off the bed with the toolhead.
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, and the loop repeats.

For how matching, scheduling and verification work in detail, see the AutoPrint overview.
