Welcome
Your MakerGear M3 3D Printer has arrived!
Do not change your M3’s rmware unless you know exactly
what you’re doing or have been instructed to do so by
MakerGear support.
This booklet can also be found on the MakerGear website at
setup.makergear.com, where you can access additional, more specic
information and resources.
Following minimal setup, your M3 is ready to print out-of-the-box. To ensure
safety as well as high quality printing, carefully follow the Setup instructions
included in this booklet.
This machine was assembled at the MakerGear shop in Beachwood,
Ohio, USA, and was tested for at least six hours to ensure that it was fully
operational at the time of shipping.
Do not remove the lm of yellow polyimide tape from your M3’s
glass bed; this functions as your print surface, and should be
facing up.
1. To protect against electrical shock, do not put the machine body, cord,
or electrical plug in liquid. If your printer falls into liquid, do not touch it.
Instead, unplug the unit, then remove it immediately. Do not reach into the
liquid without unplugging the unit rst.
2. This machine should not be used by children unless supervised by an
adult who understands the risks and precautions involved in its use. To
avoid potential injuries, close supervision is necessary when the unit
is used by or near children.
3. Unplug the power cord when this machine is not in use. To unplug, grasp
the plug and rmly pull it from the electrical outlet. You should never pull
the cord.
4. Avoid any contact with moving parts.
5. Keep hands/hair/clothing away from printer attachments while the unit is
operating to reduce risk of injury to persons and/or damage to the unit.
6. Do not operate your unit if it has a damaged cord/plug, is malfunctioning,
or has been dropped or damaged in any way.

4. Rotate the bed hold-down clips to point toward the front and back of the
bed in order to secure the glass in place.
5. Install the Spool Holder with the 4 included screws using the 3 mm allen
key, ensuring that the longer side is facing up. Place your PLA spool on the
Spool Holder so that the lament unwinds upward.
7. Insert the 6-Position Power Supply Connector into the 6-Position
Electronics Connector, making sure that it is SECURELY IN PLACE in the
electronics case. Connect the power supply cord to the power supply. Next,
plug the power supply into a wall outlet and ip the switch (B) to the on
position.

6. Unpack the power supply and set the voltage switch (A) to the voltage
supplied through your outlet. There are only two settings: 115 V (for 100–
130 V) and 230 V (for 220–240 V). To nd the standard voltage level for
your country, visit
www.worldstandards.eu/electricity/plug-voltage-by-country/
Visit our YouTube channel, MakerGear, for step-by-step instructions on
how to remove the V4 hot end and remove/mount a nozzle.
If you wish to remove or change your nozzle, you must rst remove the
entire hot end. Attempting to unscrew the nozzle directly from your M3
will damage the hot end.
Some of our users choose to print with nozzles that are either larger or
smaller than the 0.35 mm nozzle included on the M3 in order to
accommodate specic printing needs. If you plan to print with differentsized nozzles, we recommend keeping each nozzle installed in a separate
hot end, as this allows you to switch between nozzles more easily.

A Note About Nozzles
Using a desktop or laptop computer, navigate to setup.makergear.com and
follow the provided steps.
Step 1: On the Setup page, enter your printer’s serial number, which is
located on the back of the printer. Next, connect your computer to your M3’s
Wi-Fi, using the provided network name and password, in the same way that
you would connect to any other Wi-Fi source.
Step 2: After moving to the Step 2 tab, click the temporary setup link and
log in to OctoPrint with the provided username and password.

Software Setup
MakerGear 3D printers are compatible with a wide variety of hosting and
slicing programs. The free onboard software supplied with the MakerGear
M3 is a specialized version of OctoPrint called OctoPrint for MakerGear. It
is an open-source, easy-to-use tool that gives users total control over their
3D printing workow.
OctoPrint’s basic functions include simple tasks such as controlling and
monitoring your printer, as well as more advanced operations like slicing
les. It can be expanded through its versatile plugin system, a diverse
library of community-developed plugins offering specialized functionality,
which is useful for all users.
1. In OctoPrimnt, heat your extruder to the appropriate temperature in the
“Temperature” tab. If switching between lament materials (e.g., PLA
to ABS), heat your extruder to the hotter of the two materials’ printing
temperatures in order to purge the old material and properly extrude the
new material.
2. In the “Control” tab, click “Retract” while pulling gently on the old lament
until it is released from the lament drive.
3. Cut the end of your new material so the tip is at, and feed it into the
lament drive. While applying gentle downward pressure, click “Extrude”
until you can see the lament extruding from the nozzle.
If you are unable to feed lament properly, try cutting the tip at an
angle.

Changing Filament
After you’re connected to the printer, proceed to OctoPrint’s Quick Check,
which will help you load your lament and ensure that the bed of your
machine stayed level during shipping. Once you complete the Quick Check,
your machine will be ready to print. You will not have to go through the
setup process again unless you change networks or reset your printer.
Step 3: OctoPrint will inform you that you are not connected to the internet.
Click “Wireless Conguration,” then select your home network and enter
your home network’s password. Connecting may take a few minutes. If
OctoPrint continues to say you are not connected to the internet, refresh the
page.

Maintenance & Storage
Weekly Maintenance (every 50 hours)
Ensure that your bed is at the correct height and properly leveled. To do so,
log in to OctoPrint and proceed through the QuickStart process in order to
complete the following steps:
1) Check Starting Height 2) Check Bed Level
Ensure that the print surface is free of defects (torn or bubbled polymide
tape) and dust/dirt/grease, and replace tape or clean surface with
appropriate cleaner (alcohol/water at 50%/50% is recommended).
Monthly Maintenance (every 200-250 hours)
Ensure that the machine is free of dust and lament debris, and clean it if
necessary. Focus areas include fans and fan guards, lament surface and
lament drive, and the entire frame. Clean oil from the X and Y linear rails
