Snapmaker A150 User manual

Welcome to
the world
of making
Three years ago, when we were designing
the Snapmaker Original, we broke the
rules of traditional desktop 3D printers and
created the first modular 3-in-1 3D printer
on the market. At first, The Verge and a lot
of other reviewers doubted that “Snapmaker
is an upcoming Kickstarter project with a
lofty goal: to be the holy trinity for at-home
makers by using detachable modules to
convert between a 3D printer, a CNC carver,
and a laser engraver,” and “At the price that
Snapmaker is selling, it’s possible the whole
thing is too good to be true.” We knew people
had a lot of uncertainty about our project
and were hesitant to back us because of
the complexity of designing and making
such a product. Despite all the doubts, we
worked hard on pushing the boundaries
of possibility, and we eventually made the
impossible possible. Not only did we fulfill
all the rewards, but we also sold over 10,000
units all over the world in 2018. And in 2019,
we launched the Snapmaker 2.0. We went
beyond our limits once again. Our goal
is to build a system behind our modular
3D printers and give you the best maker
tools that can work for all your projects. As
creatives we all desire to make something
wonderful and creativity makes us feel
alive. The Snapmaker 2.0 will help you turn
your idea into reality. This quick start guide
will guide you through your maker journey
and take you from building your own 3D
Printer/Laser Cutter/CNC Carver to making
your first creations utilizing all these tools.
Congratulations on becoming part of the
Snapmaker community! Thousands of
people like you are using the Snapmaker
to explore, make, and share in the world
of making. We are strong believers that
wonderful things will happen when creative
minds meet the ideal tools. Have fun making
and see you out there!
Team Snapmaker
Make Something Wonderful

This machine is built for innovators. Our goal is to assist
you to make the world a better place with a machine we
built with love. The difference could be something as
small as a Christmas gift, or something as ambitious as
exploring unknown territories of our mankind. Dream big
and make it happen.
Happy Making
Snapmaker is not only a 3D printer, but also a powerful
machine that you can modify with all kinds of addons. You
can equip your Snapmaker with an enclosure to protect
you and your family from laser and dirt particles. New
addons are coming soon with more exciting features.
Please stay tuned.

Before You Start
Stop using this product if any of the following occurs. Turn off the machine immediately.
- There is a fire in this machine which persists after the machine turns off.
- The machine stops unexpectedly.
- You see any damage to the interior components of this machine.
- You notice unusual light or an unusual sound coming from this machine that was not occurring previously.
3D Printing Safety
- Do not touch the nozzle, print sheet and heated bed when the machine is printing or heating.
- Always unplug the machine before performing maintenance or modifications.
- Set up the printer in a well-ventilated place when printing with ABS. The melting of some materials may
release toxic fumes.
Laser Safety
- The laser tool is a class 4 laser. You are only allowed to operate the laser tool if you have a sufficient
specialized and safety knowledge: You must know the physical properties as well as the biological
effects of laser radiation, the legal bases and rules of technology, the laser classes and their dangers, the
implementation of safety measures.
- Operate the machine with an enclosure covered and wear the Laser Safety Goggles.
- Never expose yourself to the laser beam. Proper use and care of the laser tool are essential to safe operation.
- Operate the laser tool when it is exhausted to the outdoors or through an air filter. The melting of some
materials may release toxic fumes.
- Always unplug the machine before performing maintenance or modifications.
- Remove any reflective material from the work area underneath the laser module. Reflective material can
cause uncontrolled scattered radiation.
CNC Safety
- Age Recommendation: For experienced users and users age 18 and above.
- Put the machine into an enclosure and wear the CNC Safety Goggles.
- Always have the material securely clamped. Never attempt to hold the workpiece with your hands
throughout the CNC carving process.
- Always unplug the machine before performing maintenance or modifications.
- If the bit or workpiece become jammed or bogged down, turn off the machine immediately. Wait for all
moving parts to stop and unplug the tool, then work to free the jammed material.
- Do not touch the bit or collet after use. After usage, the bit and collet are too hot to be touched with bare hands.
- Some dust created by CNC carving and cutting contains chemicals known to cause cancer or other
reproductive harm. To reduce your exposure to these chemicals: work in a well-ventilated area and work with
safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

3.2.1 Calibrate the Bed
How It Works: Auto Leveling
The 3D printing module conducts a compensation leveling procedure, with the sensor measuring the distance
between the nozzle and the heated bed at specific points. The movements of the extruder are adjusted to
ensure that the nozzle and the heated bed are at an optimum distance throughout the printing process.
How It Works: Adjusting the Z Offset
Z Offset is the distance between the tip of the nozzle and the print surface. Adjusting the Z Offset is the
process of tweaking the height of the nozzle by tiny increments. A proper Z Offset value helps ensure the first
layer of your print sticks to the print sheet.
