Set-Up

Do not update the firmware on your M2 unless you've made a hardware change that requires an update.
Carefully remove the foam from the top of the printer and from inside the printer frame.
Remove the HBP from its slot in the foam and place it on the 4 legged “Spider” inside the frame, with the glass facing up.
Remove the printer from the bottom foam. Remove and read WARNING sheet from underneath your borosilicate glass bed by removing the binder clips. Then secure the bed to the HBP using the bed hold‐down clips on each corner of your bed.
Do not remove the yellow polyimide tape from the glass.
Unpack the power supply and set the Voltage Switch 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 find the standard voltage level for your country, visit https://www.worldstandards.eu/electricity/plug‐voltage‐by‐country/
Insert the 6 Position Power Supply Connector into the 6 Position Electronics Connector SECURELY IN PLACE in the electronics case—note that the power supply connector should run under all other wires.
Next, plug the power supply into a wall outlet and flip the power supply switch to the on position.
Install the Spool Holder with the four screws using the 3 mm allen key, ensuring that the longer side is facing upward.
Place your PLA spool on the Spool Holder so that it unwinds upwards through the Filament Guide and feed it through. Cut the PLA so the tip is flat, then feed the filament into the filament guide tube and into the Filament Drive (if you have trouble feeding filament with a flat tip, then try cutting it at a 45 degree angle).
Download the MakerGear Quick Start App via the link included in "QuickStart.pdf" on your SD card (or via https://www.MakerGear.com/pages/QuickStart‐App ).

Carefully follow the app's step‐by‐step instructions in order to create your first print:

Connect: Install driver (Windows users only), connect to M2.
Check Platform: Check starting height, check bed level, make adjustments using instructions provided by the app.
Load Filament: Heat HBP & extruder, properly extrude filament.
Print: Select "Bracelet.g" from your SD card, click "Print"

After printing "bracelet.g", you will be given three options:

Click Retry if your first print was unsuccessful ‐ this will return you to the check platform section in order to identify and address any issues with your platform that may have caused print defects.
Click Print Another File if your first print was successful and you want to experience more MakerGear Magic.
Click Done to navigate to the "Advanced" tab, where you can find manual controls for your M2 as well as a real‐time display of the temperatures and coordinates of your extruder and HBP.

A Note About Nozzles

If you wish to remove or change your nozzle, you must first remove the entire hot end. Any attempts to unscrew the nozzle directly from your M2 will damage the hotend. Some of our users choose to print with a nozzle that is either larger or smaller than the .35 mm nozzle included on the M2 in order to accommodate specific printing needs. If you plan to print with different sized nozzles, we recommend keeping each nozzle installed in a separate hotend ‐ this allows you to switch between nozzles more easily.

Maintenance & Support

Weekly (every 50 hours)

Ensure that your bed is at the correct height and properly leveled. To do so, open the MakerGear Quick Start application and follow the commands within the Set Up process in order to complete the following steps:
- Check Starting Height
- Check Bed Level
Ensure that the print surface is free of defects (torn or bubbled tape) and dust/dirt/grease, and replace tape or clean surface with appropriate cleaner (alcohol/water at 50%/50% recommended).

Monthly (every 200‐250 hours)

Ensure the machine is free of dust and filament debris, and clean if necessary. Focus areas include fans and fan guards, filament surface and filament drive, and the entire frame. Clean 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 sufficient. Once applied, move that axis through its full travel multiple times to spread the oil.

Shutdown & Storage

If using your M2 regularly, then turn off the power supply and unplug both the power supply and USB cords when finished.
If storing your M2 for a period of 1‐2 weeks, follow the instructions listed above AND store the filament spool in its original bag (fully sealed, with the desiccant packet inside).
If storing your M2 for a period of 2 weeks or more, follow the instructions listed above THEN cover your entire machine in order to protect it from the buildup of dust and other airborne particles.

DO NOT unscrew your nozzle directly from your M2!
To change or remove its nozzle, you must first remove the entire hot end. Visit our website and YouTube channel for step-by-step instructions on how to remove the hot end and change its nozzle.
