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 specic
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

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 specic printing needs. If you plan to print with different-
sized nozzles, we recommend keeping each nozzle installed in a separate
hot end, as this allows you to switch between nozzles more easily.

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 workow.
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.
