Start here, Stage 2 in 6 steps

Follow these six steps in order. Total hands-on time is about 1-2 hours per printer. The longest wait is the 6-10 hour hardware print for step 1; from step 2 onward you can move quickly.

1. Print the hardware parts

   Download the 3MF bundle for your printer from MakerWorld and print it on your Bambu. Every FarmLoop install depends on these printed parts.

   6-10 hrs print

2. Assemble the kit

   Mount the bender, PCB, cables, and tilted feet on your printer. Separate guides for each Bambu model, pick yours on the next page.

   15-45 min

3. Update the firmware

   USB-C flash the latest firmware to the controller board from Chrome or Edge. Takes about 90 seconds.

   ~2 min

4. Choose your trigger mode

   Mechanical (manual limit-switch presses) or Digital / Full MQTT (printer talks to the FarmBoard over Wi-Fi, fully automatic). Pick one - you can switch any time.

   2-5 min

5. Verify your installation

   Power the board and watch it self-test (A-series) or long-press the outer door button to run the P/X-series component test. Confirms every element is wired correctly before you run a real print.

   5 min

6. Run the activation test print

   Slice the universal test file, process it in the FarmLoop app, and run it end to end - the exact workflow every production print uses.

   5 min

Good to know: the board’s web page

Several steps (firmware, Digital trigger mode, logs) send you to the FarmBoard’s built-in web page, called OTA mode. If that term is new, read Accessing the board (OTA mode) once - it explains how to open the page and what each card does.

How to use this guide

• Read each step’s full article, the cards above are one-line summaries. Follow the link, do the work, come back.
• Don’t skip step 5, it’s tempting to jump from “I assembled it” to “run a real print”, but the install verification in step 5 catches wiring mistakes before they damage anything.
• If something breaks mid-flow, head to Troubleshooting. The article for your symptom will link back to the right step here.

Prerequisites

Before step 1, make sure:

• Your printer is supported, check Compatibility
• You have a FarmLoop Pro subscription, sign up at app.3d-farmers.com, or if you already have Skool VIP, Pro is bundled
• The Stage 2 kit has arrived and is unopened, if anything’s damaged in the box, open a support ticket with photos before starting assembly

Where it leads

After the last step, the typical path is:

• Queue more prints through the FarmLoop app
• If you have 10+ printers: look at SimplyPrint integration
• As you hit edge cases: Troubleshooting is sorted by frequency

Have fun.
