Aufero 2.0 is a superior, more advanced version of Ortur's original Aufero 1.0 laser engraver. Aufero 2.0 is a larger machine with a square frame gantry (no cantilever), an all-aluminum metal construction (including the feet risers) and a low centre of gravity gantry, which makes the machine more stable at higher speeds.
The Aufero 2.0 laser engraver has four detachable metal sections, which attach to one another
via 8 metal screws. The frame enclosure measures
57cm deep, 13.5cm high and 59cm long and weighs 3kg. Aufero 2.0
integrates an OLM-PRO-V1.2 motherboard with a 32-Bit ESP32 MCU SoC
(system on a chip) and three NEMA 17 stepper
motors driven by a rubber drive belt. Two stepper motors
drive the y-axis, while the other stepper motor drives the x-axis.
The Aufero 2.0 laser engraver comes with safety goggles, as well as engraving materials including metal panels (x2), paperboard (2x), plywood (x4), leather (x2) and black cotton fabric denim jeans (x2). The safety goggles have green lenses with side shields
and adjustable temples so, you can wear the safety goggles
over a pair of glasses.
The only downside about these green safety
glasses is that they don't have an OD rating. When it comes to laser
goggles an OD rating is important. The
higher the OD (optical density) value, the safer the safety goggles
are. For example, safety goggles with an OD rating of 1 have a 10%
transmittance of light; whereas goggles with an OD 3 rating have a
0.1% transmittance of light.
Compared to the Aufero 1.0 laser engraver, which comes with pre-assembled, the Aufero
2.0 laser engraver enclosure has to be assembled, making it slightly
more daunting for a beginner user. That said, assembling the Aufero 2.0 laser enclosure is
relatively straight forward. It's just a matter of attaching a few
screws, connecting the
small molex type connectors and adjusting the height of the laser
module.
The only fiddly aspect of setting up the Aufero 2.0 is having to
adjust the resistance of the black roller wheels. If too tight the
laser module won't be able to smoothly glide across the working area of
the Aufero 2.0 laser, which is 390mm by 390mm (39cm/15.3 inches). The white cable, which connects to the laser module it is a 22AWG cable, measuring 56cm long (22 inches). The thicker black cable measures 60cm long (23 inches).
There
is a quick start user guide, which shows the part lists you get but it
is no comprehensive enough so, it does not detail how to assemble the
unit and how it works. Ortur does have video tutorials on YouTube, which
you can look up for help and guidance.
A 1.8 meters long USB cable is included for connecting the Aufero 2.0 laser engraver to a desktop computer or laptop's USB port. The Aufero 2.0 laser engraver also requires external power (48 watts) to run. A standard DC barrel power adapter (1.5
meters) is included so, you don't have to buy one. You can also use a laptop power adapter, as long as it has a
similar rating (24V/2A).
The
Aufero 2.0 laser engraver comes well packaged inside thick protective
foam and unmarked outer cardboard box, which is nice for privacy as it
does not disclose the contents within.
In
terms of performance, Aufero 2.0 and Aufero 1.0 are similar. They both
support 3 interchangeable lasers, including a fixed focus,
short focus and long focus (with air assist for cutting)
laser modules for engraving and cutting a variety of materials,
including plywood and even glass.
For glass engraving, you will have to paint the
glass surface with a dark color paint if you want to successfully
engrave on glass. With ordinary plywood, the long focus laser can
cleanly cut 4mm thick plywood in just one pass when running the machine
at 100 mm/min and 100% power. You can also cut through 5mm dark acrylic
with 1 pass at 100% power. The Aufero 2.0 laser modules are not powerful
enough to cut through any type of aluminum (including kitchen foil).
Aufero 2.0 laser engraver uses the same 24V/2A
laser modules as Aufero 1.0 and
Laser Master 2 Pro S2 so, laser modules are interchangeable between
these laser engravers. You cannot use 12V laser modules with Aufero 2.0
as they are not compatible. The main advantage you get with Aufero 2.0
over is a larger work area with a
square frame, which is a lot more stable than the cantilever design of Aufero 1.0
The Aufero 2.0 y-axis stepper motors have no
end-stops (limit switches), which
prevents the laser from traveling outside of the working area and
hitting the enclosure. Because of the lack of endstops, you cannot use
automatic homing (0 position of the machine). Instead, you have to use
current position mode and manually select where you want the laser to
start.
Another drawback with the y-axis stepper motors is that they
operate independently so, you cannot manually move the stepper motors in
sync. This causes a misalignment problem when you physically move the
laser with your hand when you want to redo a cut. The only way to redo a
cut with perfect alignment is by using the move buttons in the
software. Other safety feature you get with Aufero 2.0 is a gyro tilt sensor, which
disconnects power when sensing the machine is tilted.
The
Aufero 2.0 can accurately engrave at high speeds up to 5,000 mm/min with
the fixed focus laser and up to 7,000mm/min with the other lasers
(short and long focus). You can even go higher (up to 15,000 mm/min),
although you start getting a lot of shakiness. The
Aufero 2.0 laser engraver supports open source software such as
LaserGRBL, which is free and supports Windows and Linux operating
systems. No Mac support. There is also LightBurn, which is a
subscription fee based laser software, which supports Macs, Windows and
Linux.
The
laser modules included with the Aufero Laser 2 (Aufero 2.0) engraver
look alike with the same red aluminum frame. They are the LU2-2 /
LU2-4-SF / LU2-4-LF laser modules. The Optical Power of LU2-2 is:
1-1.6W. The Optical Power of LU2-4-SF is: 4.5-5.5W. The Optical Power of
LU2-4-LF is: 4.5-5.5W. The LU2-4-SF and LU2-4-LF lasers cannot calve on
metal due to the high operating temperature (1,300-1,500°), which is
ideal for engraving pictures and colors on metal. You can buy the Ortur Aufero 2.0 laser engraver from amazon.
