MAKERGEAR M3-ID Installation and operation manual

M3-ID 3D Printer Rev. 0
to Rev. 1 Upgrade Guide

You will be upgrading your printer with:
1. M3ID-REV-1 T0 Extruder Mounting Plate
2. BLTOUCH cable
3. Zip ties
4. Four (4) M3 Bed Hold Down Clips
5. Insulative sleeve
All of the fasteners you will need are already in your printer so
make sure you don’t misplace them during disassembly.
The tools you will need are as follows:
•2 mm hex driver
•2.5 mm hex driver
•3 mm hex driver

If you have filament loaded in the T0 extruder you will need to
remove it. If not, please skip to step 6.
Open Octoprint and heat up your hotend. Set the hotend to
the printing temperature of the loaded filament (e.g. ABS: 265
C, PLA: 215 C).

Select T0 as your tool.
Retract the ‘T0’ extruder by at least 70 mm.

Remove the filament and filament guide tube from ‘T0’.
Home the Z-axis with the house shaped button. Move the Z-
axis down by around 30 mm (this will give you room to remove
the RAMBo case top later).

Shut down the printer’s raspberry pi through Octoprint or by
holding down the reset button for 10 seconds.
The raspberry pi’s green light will turn off when it is properly
shut down.

Locate your 6-pin power connector in the back of your printer.
Shut off the printer’s 24V power supply and pull out the 6-pin
power connector in the back of the printer.

Make sure you are working on the correct extruder! Looking at
the front of the printer, we will be modifying the left extruder,
it is marked as ‘T0’.
Unplug all of the molex connectors from the extruder. Each
one has a lever that needs to be pressed to release the
connector.

Use a 2 mm hex driver to remove the M3x45mm flat head
screw in the bottom-right of the filament drive fan.
Rotate the filament drive fan clockwise to expose the screw
heads beneath.

Use a 2.5 mm hex driver to remove the two (2) M3x25mm
screws from the filament drive. These screws have M3 washers
on them so make sure they stay together.
Now the filament drive assembly is free and can be set aside
for later use.
