Introduction
You already know about the incredible things you can do with a Glowforge 3D laser printer. With a
Compact Filter, you can do those things anywhere.
But before you can do any of that, you’ll need to read the information in this manual.
Our job is to make sure that every part of your Glowforge experience is delightful. Unfortunately,
right now you’ll need to read a few pages that are not delightful: the Compact Filter safety
information. They’re a little dry, and a bit scary. The safety section was written by our safety team,
in the most direct language possible, to make absolutely certain you can operate your Compact
Filter safely.
After the safety talk, we’ll get back to the fun part: unboxing, simple setup... and step by step
instructions for how to use your Compact Filter during laser time!
PS: If you see anything that is unclear or seems incorrect, please let us know immediately at
[email protected].

Getting Started
Now that you’ve read all about Safety, you’re ready to get lasering!
Unboxing will take just a few minutes – we can’t wait for you to get started either. Of course, if you
encounter any challenges along the way, our Customer Success team can be reached at
[email protected] to help.
Let’s get started, shall we?
Check for damage
If your packaging or any part of your Compact Filter shipment is visibly damaged on arrival,
we want to make it right as soon as possible! Send photos of the damage to
[email protected] and wait until you hear back from us. If the Compact Filter itself is
visibly damaged, do not plug it in or attempt to operate it; contact us immediately.
Unbox your Compact Filter
Locate your Compact Filter.
Your Compact Filter must be on a flat surface, like the floor. It needs to be positioned so
that the 8 foot exhaust hose can connect to the back of your Glowforge while making no
more than three 90-degree bends.
Your Compact Filter blows air out, so ensure that there are no obstructions within two
inches of the vents on either side.
Copyright Glowforge, Inc. 2018 7
Vents are on two opposite sides
Unseal your Compact Filter box.
Carefully cut tape sealing the top of your Compact Filter box and open it. Remove the
power cord and the top piece of foam.
Remove the Compact Filter.
The Compact Filter is heavy, so have a friend help. Grasp the two handles on top of the
Compact Filter through the clear plastic bag and lift the filter out of the box. Place it on the floor.
Copyright Glowforge, Inc. 2018 8
Remove the bag.
Lift the clear plastic bag over the top of the filter to remove it.
Save the packaging material including the box, foam, and bags.
Copyright Glowforge, Inc. 2018 9
If you need to move your Compact Filter, for example to ship it back for warranty service,
you’ll need all the original packing materials. The Compact Filter cannot be shipped safely without
the original packaging materials.

Connect Compact Filter to your Glowforge
Connect Compact Filter to Glowforge Printer with exhaust hose.
Take the exhaust hose and two ring clamps that came with your Glowforge Printer. If you
would like a new one, you can purchase a new one in the Glowforge shop:
https://shop.glowforge.com/products/hose?taxon_id=57
Your Glowforge printer came with an accessory
pack that includes the exhaust hose and two
ring clamps (shown on the left side)
If you are using the exhaust hose to vent to the outside, you may reuse the hose, and you
may skip this step since the hose is already connected to your Glowforge.
Squeeze the two ends of the ring clamp together to make it larger, then slide the end over
the hose.
While squeezing the ring clamp again, slide the hose and the clamp over the the exhaust
connection on the back of your Glowforge printer. The clamp pressure will hold it in place.
Let go. Check that the clamp is holding the exhaust hose tightly to the exhaust connection.
Make sure the hose does not come off with a gentle tug.
Copyright Glowforge, Inc. 2018 12
Connect Hose to Compact Filter
Put the other clamp around the other end of the hose. Repeat the procedure above to
attach the exhaust hose to the top of the Compact Filter with the ring clamp.
Keep the hose as straight as you can, with no more than three turns of 90 degrees or less.
Make sure the hose isn’t twisted, pinched, kinked, punctured, or flattened. If there is extra
hose, do not let it sag; wrap it tightly with duct tape to keep the hose length as short as
possible.
Copyright Glowforge, Inc. 2018 13
Connect to electrical power
Verify that the power switch is “Off” (the 0 side depressed, as shown).
Verify the filter is installed and the lid is firmly closed.
Plug the power cord into the back of the Compact Filter, then plug the power cord into the
electrical socket. A standard grounded household socket works well.
Copyright Glowforge, Inc. 2018 14
Enable the Compact Filter in the Glowforge UI
1) Go to https://app.glowforge.com and log in, if necessary
2) Click the “Trace” button
3) Click the gear icon, and then click the switch next to “Compact Filter attached”. When
you are done, the circle should be on the right, and the switch should turn teal.
The fans will now run at a lower speed during every print on this machine, to match the
Compact Filter’s internal fans.
Turn your Compact Filter knob to the right setting.
The knob on the Compact Filter controls the power to the fan. When it is too high or too
low, your Compact Filter will not work properly.
When you first use your Compact Filter, turn it to “New”. The fan will use its lowest power
setting, which is the best setting for a new filter. Do not use a higher setting, as more power will
move air too quickly, and smoke and fumes may not be completely removed.
After you have used the filter for a while, the filter cartridge will start to fill. More power
will be required to move the air through the Compact Filter, and the “New” setting will no longer
Copyright Glowforge, Inc. 2018 15
reduce smoke and fumes. If you find there are still smoke and fumes on the lowest setting, use
the middle setting, halfway between “New” and “Full”.
Finally, when the filter cartridge is almost full, it will again stop reducing smoke and fumes,
and more power will be required to fully eliminate smoke and fumes.. Turn the knob to “Full”.
The bottom setting is off; the knob
turns clockwise.
To begin, set your Compact Filter knob to “New”.
Your Compact Filter is now ready for use, with the fan off.
Print something amazing
Perform the following steps for each print.
Choose your materials.
Your Compact Filter has been tested with a wide variety of Proofgrade materials, and
designed to work with all laser-compatible materials. However, some materials, like Proofgrade
Draftboard or MDF, will cause your filter cartridge to fill up and require replacement much more
quickly than others.
Turn on your Compact Filter.
Use the switch next to the power cord to turn your Compact Filter on before each print.
Run your print.
Ensure that you use laser-compatible materials, like Proofgrade hardwood, plywood, and
acrylic. Different materials will fill the filter cartridge at different rates. MDF and Proofgrade
Draftboard are not recommended, as they will cause the filter cartridge to fill quickly.
Copyright Glowforge, Inc. 2018 16
Turn off your Compact Filter when you are done printing.
Use the switch next to the power cable to turn off the Compact Filter when the Glowforge
software interface indicates that the print is complete.
Materials will have an odor when they’re removed. If you prefer, you can reduce this odor by
leaving your Compact Filter running for longer after the print is complete.
Cleaning, Service & Moving
Unplug your Compact Filter off before cleaning, moving, changing the filter cartridge, or doing any
other cleaning or maintenance.
Change Filter Cartridge
When you detect smells during printing even when the Compact Filter dial is set to “Full”, it’s time
to change the filter cartridge. Here’s how.
Turn off and unplug your Compact Filter
The power switch is located on the back, next to the cord. Turn it off first, then unplug it
from the wall.
Open Compact Filter
There are four latches holding the top of the Compact Filter in place. Lift the bottom of all
four latches to release them. You do not need to remove the exhaust hose to change the filter
cartridge.
Remove and dispose of old filter cartridge
Grab and lift the two fabric handles to remove the filter cartridge from the Compact Filter.
Dispose of the used filter cartridge in the garbage.
Copyright Glowforge, Inc. 2018 17
Lift the filter cartridge out
Replace with a new filter cartridge
You can purchase new filter cartridges from https://shop.glowforge.com. Unwrap the filter
cartridge and inspect it for possible damage. Lower the new filter cartridge in the same way you
removed the old one.
Latch the lid closed and recheck the exhaust hose.
Inspect each latch to ensure it is fully closed. Grab the lid handles and pull upward on the
lid to ensure it does not come off. Finally, check the exhaust hose to ensure it has not become
disconnected from either the lid or the back of your Glowforge.
That’s it - you’re ready to print!
Cleaning
Turn off and unplug your Compact Filter off before cleaning. Ensure that the Compact Filter is
closed before cleaning; interior areas should not be cleaned. You can clean all exterior surfaces
with a rag dampened with isopropyl alcohol. Do not spray liquids on the compact filter as they
may get inside.
Moving
For protection, the Compact Filter must be packed in its original packaging when moved to a new
location. Whether it’s for a big move, taking your Glowforge printer and Compact Filter to an event,
or for warranty service, you’ll need to package your Compact Filter properly with the original box
and packing materials. The Compact Filter cannot be shipped safely without the original packaging
materials.
Copyright Glowforge, Inc. 2018 18
To repack your Compact Filter, power the unit off and disconnect the power cord. Disconnect the
exhaust hose and hose clamp from the lid. Re-pack in the original packaging.
Troubleshooting
Reducing Odors
The Compact Air Filter is designed to allow you to safely and comfortably operate your Glowforge
printer indoors. It will dramatically reduce odors, smoke, and fumes to safe levels. You should
smell little to no odor coming from the exhaust vents of the Compact Filter itself.
Note, however, that even when used properly, odors may still occur from the following:
●Opening the lid after a print. Tiny amounts of smoke and fumes remain trapped in the
crumb tray, and will escape when the lid is opened and the material is removed. This can
be reduced by leaving the material in the Glowforge for a minute or two before removal.
●The materials themselves. After printing, the materials may have an odor for as long as a
day or two. This can be minimized by using Proofgrade material, removing and disposing
of the protective coating (which has the bulk of the odor), and by setting the materials aside
for a day.
●The Glowforge itself. After being used for many hours, tiny particles of dust and resin will
accumulate on the Glowforge itself. To minimize the odor, keep the lid closed when not in
use, clean according to the Glowforge printer user manual, and leave the Glowforge
connected to the Compact Filter when not in use.
Eliminating smoke and fumes
If you detect a strong, sharp smell that also causes eyes, nose, or throat irritation, or if there is
visible smoke escaping your Glowforge printer while the lid is closed, your Compact Filter is not
operating properly. Discontinue using your Compact Filter and follow these instructions.
1) Ensure your Compact Filter is turned on before every print, and left running until the print
is complete.
2) Check if the exhaust hose is securely connected to the Glowforge printer and the Compact
Filter.
3) Check if the Compact Filter is enabled in the Glowforge UI. You will only need to do this
once. After it is enabled, all users will have it enabled from that point forward.
4) Make sure that, when you turn on your Compact Filter, you turn it on to the right setting. If
the fan is moving too slow or too fast, the filter will not work properly.
5) Check if the hose is connected properly, with no more than three 90 degree turns.
6) Check if the materials you are using are laser-compatible. The Compact Filter has been
tested with Proofgrade materials; other materials might have smoke and fumes that are
not fully removed by the Compact Filter.
Copyright Glowforge, Inc. 2018 19
7) Change the filter cartridge. If you have been printing for a while, it may be time to replace
your filter cartridge.
8) Inspect all four latches to be sure they are tightly closed.
9) Check the hose to make sure it is not kinked, squished, or twisted.
10) Remove the hose and inspect the inside to ensure it is not obstructed.
11) Review the “Reducing Odors” section above for other sources of smell.
If all of these do not help, you are using a new filter and the “New” setting, and you are
experiencing eye, nose, and throat irritation when using Proofgrade materials with your Compact
Filter, stop using your Compact Filter and contact Glowforge support.
Compact Filter doesn’t turn on
If the power switch is on, the machine is not running, and the power indicator doesn’t light up, the
fuse may need to be replaced.
Turn off and unplug your Compact Filter
Remove and replace the fuse next to power switch
We have included a free spare fuse with your Compact Filter.
