The safety net for hands-off bed clearing

AI bed check: verify the bed is clear before the next print

AI bed check watches your printer's camera between jobs and confirms the bed is actually empty and properly seated before AutoPrint starts the next print. If a part is still on the plate, the plate is missing or sitting wrong, AutoPrint is paused - so your fleet never crashes a new print into the last one.

However the bed gets cleared, AI confirms it's really clear

Bed clearing - whether by hand, by a hardware mod like FarmLoop, or by your own gcode macro - can occasionally fail: a part sticks, a plate is put back wrong, or someone forgets. AI bed check is the camera-powered check that catches it before the next print starts, so unattended printing stays safe. It's currently in beta and free to use as part of AutoPrint.

What is AI bed check?

AI bed check is a safety and verification step for AutoPrint. After a print finishes and the bed is cleared, SimplyPrint sends a frame from your printer's camera to our bed-check AI, which decides whether the plate is empty and correctly seated. If it isn't, AutoPrint is paused and the next job is held back until the bed is genuinely ready.

It's deliberately lenient about the things that don't matter - a tiny, inconsequential bit of stray filament won't block a print - while still catching a whole leftover part, a missing plate or one that's been put back off-center. That makes it especially useful for plate swappers, where the wrong or misaligned plate is exactly the kind of mistake that ruins a print.

What the AI can see

Every check returns one of four results, and AutoPrint reacts to each automatically.

Clear

The bed looks empty and ready, so AutoPrint goes ahead and starts the next job.

Print detected

The previous print is still on the bed, so AutoPrint is blocked until it's removed.

Object detected

Something unwanted is on the plate, or the plate is missing, off-center or wrong - AutoPrint is blocked. Great for plate swappers.

Could not confirm

An obstructed view or poor lighting means the AI isn't sure, so it waits and retries once before continuing.

When the bed isn't clear, AutoPrint pauses

You stay in control

If the AI decides the bed isn't ready, the AutoPrint widget shows an AI detected bed not clear card telling you AutoPrint is paused until the print is removed from the bed, with an AI-generated note explaining what it saw. From there you can hit Mark as removed to tell SimplyPrint the bed is clear and let AutoPrint carry on, or Disable AI bed check to jump straight to the setting. Every detection has a thumbs up / thumbs down so you can tell us when it got it right or wrong, and the model keeps improving.

How to turn on AI bed check

It's a single toggle inside your AutoPrint settings - turn it on per printer, or roll it out across a model or your whole account.

Open AutoPrint settings

On the printer's control panel, open the AutoPrint widget and go into AutoPrint settings.

Enable under Safety & verification

Toggle AI bed check on, set your clear-bed timeout in seconds, and save.

What you need to use it

AI bed check only runs for AutoPrint-managed prints - it doesn't apply to prints you start manually.

AutoPrint enabled

The printer needs to be running AutoPrint, with a clearing method set up.

A working camera

The AI reads a frame from your printer's camera, so a camera connected to SimplyPrint is required.

A clearing method set up

A way to clear the bed - by hand, hardware, or your own gcode - so the plate is actually cleared before the AI checks it.

Stacks on top of any clearing method

AI bed check doesn't replace your clearing method, it backs it up. Run it alongside manual mode, a hardware mod like FarmLoop or your own bed-clear gcode, and whichever path you use, the AI gives the final yes/no before the next print starts. FarmLoop can even run AI bed clear detection, powered by SimplyPrint, to confirm the push-off worked.

Plan access: what plan do I need?

AI bed check runs through AutoPrint. It's currently in beta and free to use as part of AutoPrint, and may become a separately paid add-on in the future - we'll be upfront when that changes. AutoPrint is included on Pro as 1 license (up to 5 total), and unlimited on Print Farm, Enterprise and Education.

Frequently asked questions

It looks at a camera frame and decides whether the bed is empty and properly seated. It returns one of four results: clear, print detected, object detected (which also covers a missing, off-center or wrong plate), or could-not-confirm. AutoPrint only starts the next job when the result is clear.
Yes. AI bed check reads a frame from your printer's camera, so a working camera connected to SimplyPrint is required. Without one, the feature won't activate.
No. AI bed check only runs for AutoPrint-managed prints. Prints you start by hand are not checked.
That's exactly what it's for. When no one is in the room, AI bed check is the step that confirms the bed is clear before each new job, so an unattended printer never starts a print on top of the last one.
If the view is obstructed or the lighting is poor, the AI returns could-not-confirm. Rather than guess, AutoPrint waits and retries the check once before deciding whether to continue.
AI failure detection watches a print while it's running to catch spaghetti and failures. AI bed check runs between jobs to confirm the plate is empty before the next print starts. They solve different problems and work well together.
During the beta, yes - it's included as part of AutoPrint at no extra cost. It may become a separately paid add-on in the future, and we'll let you know clearly before that happens.
