Bambu Lab P1S Without the Cloud — LAN-Only mode step by step.

The P1S is the enclosed CoreXY printer for those who want speed and solid engineering without the flagship premium — popular in small print farms too. Here's how to run it without the manufacturer cloud in LAN-Only mode.

Basics

What to keep in mind for the P1S in LAN-Only mode.

The P1S is enclosed and AMS-capable, but comes without some of the flagship's convenience sensors. For cloud-free operation that is irrelevant: in LAN-Only mode you print and monitor locally via the slicer on the same network.

As with the other models, LAN-Only mode removes remote access from outside the network and the cloud-bound convenience services. In small print farms the P1S is a pragmatic base — as long as it stays at a few devices.

Enclosed CoreXY design, AMS-capable
Local printing and monitoring on the network remain usable
Remote access from outside the LAN and cloud convenience drop out

Enable LAN-Only mode — in brief

On the printer display: Settings → General → LAN-Only mode, then confirm.
The printer shows an access code and its local IP address.
In your slicer (Bambu Studio or OrcaSlicer), add the printer via IP and access code.
Or print via microSD card with no network at all.

The exact menu wording may vary depending on firmware version.

From single printer to fleet

Multiple Bambu Lab P1S without the cloud — but centrally managed.

LAN-Only mode solves cloud-free operation per device. For multiple printers in production you need central job, material, user and reporting management — data-sovereign, in house. That is exactly what leanAM MES adds as an on-premise system, across manufacturers and without cloud lock-in.

FAQ

Frequently asked questions — Bambu Lab P1S without the cloud.

Can you use the Bambu Lab P1S without the cloud?

Yes. The P1S supports LAN-Only mode and then operates exclusively on the local network. You print via Bambu Studio or OrcaSlicer on the same network or via microSD card. Cloud convenience features such as remote access from outside drop out.

Is the P1S suitable for a small print farm without the cloud?

For a few devices, LAN-Only mode is a pragmatic base. As soon as several printers need to be centrally scheduled, documented and analysed, LAN mode lacks cross-device management — that's where an MES makes sense.

How do I centrally control multiple P1S without the cloud?

An on-premise MES such as leanAM combines local control of several P1S with central job, material and user management — across manufacturers and without cloud dependency.
