Extruder Gear Replacement Guide for the M3D PRO
In this guide we will explain how to replace the extruder gear for your M3D PRO. You will need
a 2.0mm/1.5mm hex screwdriver for the disassembly and you’ll want to be in a antistatic
environment. Some electronics will be exposed during the disassembly and there is a chance
you could damage them. We recommend not working on a carpeted area and to discharge
before working. You can do this by touching something metal (Not the printer) for at least one
second. Wearing an antistatic wrist-wrap would be good. Link for a wrist-wrap here

Although, it is highly recommended to use an antistatic wrist-wrap, if you do not have access
to the antistatic wrist-wrap, you can do the repair process by having a metal contact to your
body throughout the repair.
Since the M3D PRO 3D printer is highly static device as there are various PCBs involved, if the
repair process is carried out without following the above recommendation and the customer
end up frying the electronics, they would need to send back their printers to M3D headquarters
for replacement.
Step 1. The first step will be to remove the front cover from the Pro. To do this you will need
to remove the hex screws from the cover. There are a total of 8 screws in each cover. Four
screws on the top and four screws on the bottom.

Step 2. Once you have removed all of the screws you can gently start pulling the cover off the
Pro. Try pulling out the top a little first and then move onto the bottom. Keep going back and
forth from top to bottom until the cover is removed.

Step 3. Once the front cover has been removed move onto the rear cover. The process will
be similar to the front cover. The only difference will be that there is a grommet attached to the
cable assembly on the bottom that may need to be removed to remove the rear cover.

Step 4. Once the front and back covers are removed you will be left with the box top rails.
These can easily be removed by just lifting them up and off the rods.

Once the rails are removed be sure to check the rods to make sure all the spring washers are
there. You should have one spring washer on each rod. You may want to remove these and
keep them in a safe place so you do not lose them.
Step 5. If you need to remove the extruder and gantry’s from the rods continue on with this
step. Next you will need to open the software and go to Setting >>> Expert Controls >>> Basic
Controls. Once there you will notice some arrows with letters on them. Please use the Z +
arrow to move the extruder up towards the top. You can use the box in between the Z arrows
to increase the increments at which the extruder moves up and down. Keep moving the
extruder up in till it reaches the top.

Step.6Once the extruder has reached the top and cannot go up any more than it should the
software will not allow you to raise it any more. In the Gcode window of the spooler type
M1012 and hit enter then type G33 and hit enter you can now raise the gantry all the way to the
top until you will be able to remove the extruder without issue. Once free Disconnect The Pro
from the USB and Power

Step 7. Once you have the extruder and gantry’s removed, you should be able to
pull the rods out of the sliders to remove the extruder from the X rods. If you have one
of our early Pro’s then the rods might have been press fitted on. To remove these you
will need to twist the gantry’s back and forth to loosen the fit and remove the rods.
