FarmLoop Stage 2 P2S - Automatic Printing

Introducing 3D Farmers FarmLoop Stage 2, the most advanced automatic printing system for the Bambu Lab P2S.

Stage 2 takes automation to a new level by combining active build-plate bending, automatic door opening, and intelligent cooling. This enables reliable detachment of virtually any print - even large, flat-surface parts that challenged Stage 1. 

How to Start

All 3D-printed parts for this module are available here on MakerWorld, but to make the system work you'll also need the Stage 2 Hardware Kit from our Shopify store:

The Stage 2 hardware works exclusively with the FarmLoop Pro App.

How It Works

• Automatic Door Opening: One of the first automatic door opening systems for Bambu Lab you can buy. 64N of motorized force opens and closes your door on command – with a push of a button or fully automatic when in looping mode. Keep your chamber heated. Print any material. No more choosing between enclosure and automation.
• Active Build-Plate Bending: A precision linear actuator with 64N of controlled force bends the plate up to 50mm. Even parts with big surface areas release cleanly. Two-phase bending – an initial bend, short relaxation, then full flex – creates a peel front that progressively breaks adhesion from edge to center.
• Accelerated Cooling: A 6000 RPM fan pulls cold air directly onto your print and build plate, cutting cooldown time significantly. Faster cooling also shrinks the part slightly faster than the plate – creating microgaps at the adhesion interface for easier detachment.
• Smart Safety System: Force-sensing technology detects obstacles instantly – whether it's overflowing prints, a forgotten tool, or your fingers. If something blocks the door, the system triggers an error and stops your printer before damage occurs. No runaway prints. No disasters.

• Custom FarmBoard PCB
• 2× High-force linear actuators (64N each)
• Limit switch for activation
• Button for door activation
• AMS/Molex cables
• Screw set
