Six Printers. Zero Stock Configurations.

Every machine in the AxisBreak fleet has been reflashed, rebuilt, rewired, or reimagined. This is the shop-wide overview of what runs here—and why nothing stays stock for long.

If there is one thing you should know about AxisBreak, it is that nothing here runs the way it came out of the box. Every printer in this fleet has been torn apart, rewired, reflashed, and rebuilt to do exactly what I need it to do.

The common thread is simple: Klipper firmware on every machine, cameras on all of them feeding into my custom AI Print Controller, and a relentless itch to push each printer further than the manufacturer ever intended.

This is the overview—the big picture of what is humming, whirring, and extruding in the shop. Down the road, each printer will get its own deep-dive post covering every modification, every headache, and every breakthrough. For now, let us meet the fleet.

Before getting into the individual machines, there are a few things they all share. Every printer runs Klipper—through OpenNept4une, COSMOS, a rooted stock board, or a dedicated Linux host.

These two are the workhorses—the machines that run day in, day out. Both are ELEGOO Neptune 4 Pros, and both run OpenNept4une to break free from the stock firmware and move onto proper open-source Klipper.

The stock cooling and carriage setup did not cut it, so both printers received custom-printed carriages loaded with three 5015 blower fans for part cooling that can actually keep up with high-speed printing.

Under each printer sits a custom-mounted Noctua 12-inch PC fan, stepped down from 24V to 12V. That keeps the motherboards cool and quiet, because a dead mainboard at 2 AM in the middle of a print is nobody's idea of a good time.

The K1 came enclosed from the factory, which was a good start, but the firmware had to go. This machine has been rooted with Klipper installed directly, giving me full control over the motion system and print parameters that Creality's stock firmware locks away.

The hotend was replaced with a custom Microswiss unit using a ceramic heater for better thermal stability and faster heat-up times. On a BIQU Nano Tech build plate, with a camera watching every layer, the K1 fills the role of a compact, enclosed, fast printer that simply gets the job done.

This is where things get serious. The ELEGOO Centauri Carbon is a glass-enclosed machine, and that enclosure is not just for looks. It makes this the go-to printer for Nylon Carbon Fiber and PETG Carbon Fiber filaments that demand a controlled chamber environment.

The stock firmware was replaced with COSMOS firmware running Klipper, and the nozzle is ruby because carbon-fiber filaments will eventually eat through brass—and even hardened steel.

ELEGOO has also announced a multicolor unit for the Centauri Carbon, and I have one on pre-order. Multicolor carbon-fiber prints should open up some interesting possibilities.

The SV04 is a dual-IDEX large-format printer, meaning it has two completely independent toolheads on the same gantry.

Getting all of that working under Klipper was a project. The machine runs from a Dell laptop with Linux as the host, and there was very little current documentation to work from. It took serious configuration work, but it is running.

Cartographer probe, BIQU Nano Tech build plate, camera—the usual AxisBreak treatment.

The big one. The Tronxy X5SA is a large-format CoreXY printer with a 330 × 330 × 400 mm build volume, and it has probably seen more modifications than any other machine in the fleet.

Like the SV04, the Tronxy runs Klipper from the Dell Linux laptop. It is configured with a multi-tool setup (T0/T1) for future expansion.

This machine is built for the big jobs: enclosures, structural components, and anything that needs serious real estate.

Behind the printers is the infrastructure that ties everything together. A Dell laptop running Linux serves as the Klipper host for the SV04 and Tronxy.

Every machine feeds camera data into my custom-built AI Print Controller, giving me fleet-wide monitoring and control from one interface. The filament dryers—a four-spool unit for nylon and a two-spool unit for general use—keep material in print-ready condition.

This was the 30,000-foot view. Every one of these machines has a story: the late nights diagnosing firmware issues, the custom parts designed and printed on other machines in the fleet, the upgrades that worked, and the ones that definitely did not.

Over the coming posts in The Build Log, I will be doing individual deep dives into each printer—what it started as, what it is now, and everything that happened in between.
