You Don't Need an AMS to Do HueForge — Here's the Manual Swap Method

Most HueForge tutorials online assume you've got an AMS. If you don't — if you're running a P1S without the AMS unit, an A1, or an A1 mini — you can still do everything they're showing. You just become the AMS yourself.

I get this question constantly: 'Do I need an AMS to start HueForge?' The honest answer is no. Manual swapping adds a few minutes per color change and you have to be near the printer when those moments come up. That's the whole trade-off. Same prints, same quality, same workflow upstream — just one part of the process where you're the robot.

If you've been holding off on HueForge because you thought AMS was a hardware gate, this is the tutorial that gets you printing tonight.

Before you start

This tutorial assumes:

— A Bambu Lab printer without an AMS (P1S, P1P, A1, A1 mini, X1 series, anything that prints solo color out of the box)

— HueForge installed, with at least one filament profile calibrated

— Bambu Studio installed and your printer added

— 3–6 filaments to print with. Same material across all of them — don't mix PLA and PETG

— Comfort with swapping filament manually on your printer (load, unload, purge)

— Earshot of the printer for the duration of the print (the pause beep is your cue)

Why no AMS still works

Here's the thing about the AMS: it isn't doing anything magical. It's a robot that loads filament, unloads filament, and purges the nozzle on a schedule. Without one, the printer pauses at every color change layer, and you do those three things by hand. That's the full picture.

The trade-offs:

— Longer total print time. Each manual swap adds 2–4 minutes. A 5-color print = 4 swaps = ~12 minutes added. Negligible against a multi-hour print.

— Attention required. You need to be within earshot when the printer pauses. Long swaps (5+ minutes) cool the bed and risk adhesion problems — keep them brisk.

— Cheaper hardware. The AMS is $349 you don't spend, and HueForge prints look identical either way.

Most hobbyists are at the printer anyway during a HueForge print — these are statement pieces, not background prints. The manual workflow fits the situation.

The procedure

Step 1 — Set up your HueForge file as usual

Calibrate your filaments first. If you haven't, see the visual TD calibration tutorial — three filaments, ten minutes, no meter required.

Build your color stack in HueForge as you would for any print. Black on the bottom, your translucent colors stacked on top. Export the STL when the preview matches your vision.

Critical: open the Describe output (the layer-by-layer color guide). The layer heights it lists are exactly where you'll insert color change commands in Step 3. Keep that window open or screenshot it.

Step 2 — Open the STL in Bambu Studio

Drag the STL into Bambu Studio. Use the standard HueForge slicer settings:

— Layer height: 0.08mm

— First layer: 0.16mm (must be a multiple of 0.08)

— Infill: 100%

Slice the model. Don't send to printer yet — there's one more step.

Step 3 — Add manual color change commands (and pauses)

Open the Preview tab (the post-slice view). On the right side, you'll see the layer slider — every layer of the print, top to bottom.

For each layer height where HueForge said to swap colors, right-click that exact layer on the slider. Select 'Add color change' from the menu (the wording may vary slightly across Bambu Studio versions — look for the option that inserts a color change marker, not a custom G-code or a pause).

Color change markers appear as colored dots along the slider. Verify each one matches the layer heights from your HueForge Describe output. Miss one and the print finishes with the wrong color in that section.

Save / send to printer when every color change is in place.

Step 4 — Print and manage the swaps

The printer starts. The first color (your base — usually black) prints up to the first color change layer.

When the printer hits a color change layer, it pauses. The LCD shows a pause prompt. The print head parks; the bed stays heated.

The manual swap, in five moves:

1. Unload the current filament. On the LCD: Filament → Unload (or your printer's equivalent menu path). Wait for the spool to fully retract.

2. Load the next filament. Push the new filament into the extruder until it grabs. Use the LCD's Load function to feed it through.

3. Purge until clean. The first filament out of the nozzle is a mix of the previous color and the new one. Extrude 50–100mm of filament until you see clean new color flowing — this is the most common spot people skip and it shows up as muddy bands in the finished print.

4. Wipe the nozzle if any oozed filament is hanging off. A pair of pliers and a quick pinch handles it.

5. Resume the print. LCD → Resume. The print head returns to position and continues at the new color.

Repeat at every color change layer until the print finishes. Each swap, once you've got the rhythm, takes 2–3 minutes.

Step 5 — When the print finishes

Standard HueForge cleanup. Remove the print, peel any brim, and admire your work. The result is identical to what an AMS would have produced — the printer can't tell the difference, and neither can the print.

A worked example

Last poster I did on the manual workflow was a 5-filament HueForge print: black, white, two grays, and a deep red. Print time would have been roughly 5 hours straight if I'd had AMS. Without AMS, I had four manual swaps in the middle.

Each swap took about 3 minutes. Twelve minutes added to the total. Final print time: 5 hours 12 minutes, versus 5 hours flat. I'm not losing sleep over twelve minutes.

I stayed within earshot — kitchen, living room, my office is a wall away from the printer. The pause beep is loud enough that I never missed one. When the beep hit, I was at the printer in under a minute, and the swap took 2–3 minutes from beep to resume.

If you're worried about being chained to the printer for hours: you're not. You're checking in four times across a long print. That's it.

Manual is just the workflow without the robot

The AMS is a convenience. It loads filament for you, it purges for you, it doesn't beep at you. It is not, however, a capability — the print itself doesn't know whether the swap was automated or manual. The molecules don't care.

If you've been holding off on HueForge because you assumed AMS was the entry ticket, today's the day. Pick a 3-color print to start with — three colors means two swaps, and you can feel the rhythm without committing to a 6-hour test run. Once it clicks, scale up to whatever you want.
