Welcome
Your MakerGear M2 3D Printer has arrived!
Do not change the M2’s rmware unless you know exactly
what you’re doing or have been instructed to do so by
MakerGear support.
This User Guide can also be found on the MakerGear website at
www.makergear.com/pages/user-guides, where you can access
additional, more specic information and resources.
Following minimal setup, your M2 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 User Guide.
This printer was assembled at the MakerGear factory 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 the
M2’s glass build plate; this functions as the print surface, and
should be facing up.

3. To protect against electrical shock, do not put the printer body,
cord, or electrical plug in liquid. If the printer falls into liquid, do not
touch it. Instead, unplug the printer from power outlet, then remove
it immediately. Do not reach into the liquid without unplugging the
4. This printer 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 printer
is used by or near children.
2. Unplug the power cord when the printer is not in use. To unplug,
grasp the plug and rmly pull it from power outlet. You should never
5. Avoid any contact with moving parts. The printer can move quickly,
so stay clear to avoid being struck or pinched.
6. Keep hands/hair/clothing away from printer attachments while the
printer is operating to reduce risk of injury to persons and/or damage to
7. Do not operate the printer if it has a damaged cord/plug, is
malfunctioning, or has been dropped or damaged in any way. If
you are having any problems with the printer (such as temperature
errors, unexplained shutdowns, or other erratic behavior), unplug
the printer from power outlet and contact support. Do not operate a
malfunctioning printer.
1. The following safeguards exist to ensure the safety of users and to
avoid potential risks. Ignoring these safeguards can cause damage to
the printer and its environment.
8. Keep area around the printer clear. The heated build platform moves
horizontally and vertically and may cause the printer to move or dam-
age other pieces of equipment if it strikes them.

how to remove the V4 hot end and remove/mount a nozzle.
The nozzle is the brass conical piece with a six sided base. It attaches
to the other parts of the hot end and dispenses material through a
precisely sized hole.
If you wish to remove or change the nozzle, you must rst remove the
entire hot end. Attempting to unscrew the nozzle directly from the M2
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 M2 in order to
accommodate specic printing needs. If you plan to print with dierent-
sized 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

Step 1: Using the QuickStart App, print “hexa.g” from the included SD
card, which we have sliced for you using Simplify3D software. This
should take about 15 minutes to print and will serve as a comparison to
your sliced version of the same model.
Step 2: Remove your SD card from the card reader on your M2 and in-
sert it into your computer’s card reader — this will enable signicantly
faster transfer of les between you computer and the SD card. For com-
puters that do not have an SD card reader, external card readers that
connect to your computer via USB are available.

Slicing Files
If you try to dowload and print a le from the internet, you’ll notice its
format is either .STL or .OBJ, which your M2 is unable to read. In order
to print these les, you must use special software designed to“slice”
them into“.g” or “.gcode” format — this le format, known as G-Code,
gives your M2 step-by-step commands for where/how to extrude ma-
terial. The steps listed below will help you set up your slicer settings to
slice a .STL le stored on your SD card into .g format.
Step 3: Download the most recent Slic3r from slic3r.org. Your slicer
settings will be incorrect. To correct them, click “Load Cong Bundle”
under “File”and select the “cong.ini” le available on your SD card.
Step 4: Import “hexa.stl” into your slicing software, slice the le (i.e.,
click export in .g format), and then name it “hexa2.g”. Transfer this new
.g le to your SD card, eject the card from your computer, and then
insert it back into the card reader on your printer.
Step 5: Use your printer control software (e.g., Printrun by Pronterface,
available at http://www.pronterface.com/#download) to instruct your
M2 to print hexa2.g from your SD card.

1. After ensuring that your hot end is hot enough to print with your
current lament material, use the manual controls in your software
package to “Retract”while pulling lament gently until it is released
from the lament drive.
2. If switching between lament material types (e.g., PLA to ABS), heat
your extruder to the hotter of the two printing temperatures in order to
purge the old material and properly extrude the new material.
3. Cut the end of the new material at an angle and feed it into the
lament drive. While applying gentle downward pressure, use the
manual controls of your software package to “Extrude”until you can
see the lament extruding from the nozzle.

Changing Filament
If the “hexa2.g” print does not have similar strength and appearance to
the “hexa.g” sample that you printed, see the online resources oered
by your slicing software provider in order to familiarize yourself with
dierent slicing settings’impact on various aspects of print quality.

Maintenance & Storage
Weekly Maintenance (every 50 hours)
Ensure that the heated build platform (HBP) is at the correct height and
properly leveled. To do so, open the MakerGear QuickStart app and fol-
low the Set Up process in order to complete the following steps:
1) Check Starting Height 2) Check HBP Level
Ensure that the glass build plate 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 printer 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 the oil from the X and Y
linear rails and apply a fresh coat to each. A dot of oil in each of the long
grooves on the X and Y rails is sucient. Once applied, move each axis
through its full travel multiple times to spread the oil.
