Basics

Plug in Your 3Doodler

Ensure you set your temperature to ABS for ABS filament or PLA for PLA filament.

Press Fast / Slow & Insert a Strand

Press either button to put your pen in drive mode, then insert the tip of a filament spool into the back of the pen. Push gently to ensure it engages with the gears and grips properly.

Ready, Set, Doodle

It will take a few seconds for your filament to extrude.

The Buttons

Fast / Slow Button

Single-click either the fast or slow buttons to start a continuous flow of filament. Extruding filament can be stopped by clicking either button at any time. The pen may sound like it is still extruding for a few seconds after — this is normal and is simply the motor reversing the strand slightly.

Reverse Feature

Double click either button to reverse filament. The pen will pulse slightly as it reverses. If the filament is too short to reverse, carefully remove the nozzle and use the unblocking tool to push the filament out.

Feeding Spools

Feeding Spools

First, try pushing your filament gently into the pen to ensure it engages with the gears. If the filament is too short to grip, use another piece of filament or the unblocking tool to push it into the gear system.

Jammed Filament

The unblocking tool is included to help push filament out of the pen. While the pen is on and the nozzle is hot, unscrew the nozzle, double-click either speed button to reverse, then gently push filament out using the tool.

A Few Reminders

• Follow the step-by-step user manual at all times.
• Never force anything into place.
• Ensure no filament is inside when replacing the maintenance cover.
• Align tabs carefully when reattaching the cover.

Pressing on Surface

Push the nozzle firmly onto the paper and allow filament to extrude for a couple of seconds, then lift. The extra pressure helps the filament stick. We call this “anchoring.”

Incorrect

Filament bunches when not properly anchored to the surface.

Correct

Press the nozzle firmly onto the surface and hold briefly before lifting.

Nozzle Removal

Use the nozzle removal tool to gently unscrew the nozzle while the pen is on and fully heated (LED blue or green). Do not over-tighten the nozzle and keep the tool centered to avoid damage.

Tips

Keep Your Filament Clean

Use clippers or scissors to snip melted filament ends to avoid jams.

Welding Filament

While extruding, touch the tip to both pieces to weld them together.

Getting Started with your 3Doodler Start+

Not sure where to begin with your new 3Doodler Start+ pen? You’ve come to the right place! Let’s get started with a few of the basics. We’ll help get you Doodling like a pro in no time.

Basics

Micro USB Port

Plug in and recharge quickly and easily.

On / Off Switch

Slide this switch to turn it on. Allow 30 seconds for the pen to warm up. Out of power? Charge it up!

Insert a Strand

Click to start, then insert the strand until you feel it grip.

The Buttons

Click to Start, Click to Stop

One single click is all it takes to get your 3Doodler Start+ feeding. When you need to stop, one click is all it takes to stop the flow of filament. When inserting a fresh strand, it can take 10–15 seconds to extrude from the nozzle.

Jammed Filament

First try gently pushing your filament into the feed port to ensure it engages with the gears and gets gripped properly. If the strand inside the pen is not long enough to grip, use another filament strand to gently push the first strand down into the gear system.

Still Struggling?

Don’t worry, our support team is here to help. Please reach out to us here and let us know what’s going on.

Doodling Tips

Extruding Filament

Our Eco-Filament extrudes from the nozzle and hardens in a few seconds, giving you time to shape your Doodles to perfection.

Anchoring

If the filament won’t stick to paper, push the nozzle firmly onto the paper, let the filament extrude for a couple of seconds, then lift the nozzle. The downward pressure helps the filament stick. We call this anchoring.

Tips

Keep Your Filament Clean

Use clippers or scissors to snip melted filament ends to avoid unnecessary jams.

Welding Filament

While extruding, touch the tip of the pen to each piece you wish to join. After welding, you have about 5 seconds to mold the filament before it hardens.

3Doodler PRO+ Troubleshooting Guide

My Pen Won’t turn on!

• Make sure the Power Adapter is firmly plugged into both the wall and the pen.
• Be sure that the Power Adapter is connected to the correct part of the pen.
• Be sure to turn the switch on the pen to the ‘On’ position.

My Filament is extruding but it won’t stick to the paper, or it’s curling up around the Nozzle.

• Push the Nozzle firmly down against the paper, then begin extruding the Filament. This will allow the Filament to stick to the surface.
• Drag the pen and filament across the surface in a continuous unbroken line as if you were writing with a pencil.
• Keep your movements slow and steady. The Filament should hold to the paper and not curl up around the Nozzle.

My 3Doodler Pro+ isn’t extruding.

• Make sure your pen is on the right setting for the Filament you are using.
• Make sure the strand is engaged with the Drive Gear. Gently push the Strand into the Feed Port until you feel it being pulled by the
• Drive Gear on its own.If the above does not work, reverse the strand fully from the pen, snip the melted end, then reinsert and try again.In situations where the strand is too short, remove the Maintenance Cover and with the pen turned on and in reverse, try to tease the strand out with your fingers.If it is too short, put the maintenance cover back on. With the pen turned on and heated fully, unscrew the nozzle, then engage the reverse feature. Then insert the Unblocking Tool into the front of the pen to push the short strand out of the feed port.

My Filament is Leaking from around the Nozzle.

This may be caused by a loose nozzle. In this case make sure the pen is hot, and then tighten the nozzle using the tool provided. Do not over tighten it.

My Filament won’t stop extruding.

• Click the feed button once.
• If that doesn’t work, turn off and unplug your pen.
• Wait a few seconds and then plug it back in and turn it on again.

How do I reverse my unused filament?

• With the pen on and fully heated, click the Reverse Button.
• If the strand is too short, remove the Maintenance Cover and tease it out with your fingers, the pen should be on and in reverse as you do this.
• Alternatively, you can insert a new strand of the same filament and feed it through. This will push the small amount of the previous strand in the pen out through the nozzle.

My pen won’t heat up! The light stays red!

Make sure you have selected a filament type on the Menu Display. It takes about 60-90 seconds for the pen to heat up depending on the filament selected. If, after that time, the pen still does not heat up, and the Indicator Light remains Red, turn the pen OFF and then ON, and try again. If that still does not correct the issue, please contact us at help@the3doodler.com.

3Doodler PRO Troubleshooting & FAQs

3Doodler PRO Troubleshooting Guide

My pen won’t turn on

Solutions:

• Ensure the power adapter is firmly connected to both the pen and the wall outlet.
• Verify that the On/Off switch is set to On.
• If available, test a different outlet or compatible adapter—sometimes the power source is the issue.

No filament is extruding

Solutions:

• Double-check that the Indicator Light is Blue or Green, meaning the pen has reached the correct temperature.
• Press Feed once and listen for the Drive Gear—if silent, the filament may not be seated correctly.
• Try reversing the strand, snip off any melted tip, and reinsert fresh filament.

Pro tip: After reloading, wait 10–15 seconds to allow the filament to heat properly before feeding.

Filament slips or won’t advance

Solutions:

• • If the filament is too short to grip, remove the magnetic maintenance cover and push the end manually into the Drive Gear.
  • Gently wipe the feed port or gears with a soft, dry brush to clear dust or crumbs.
  • Try a new filament strand—brittle or warped filaments often fail to feed correctly.

Filaments is leaking around the nozzle

Solutions:

• Heat the pen so the nozzle is warm, then use the Nozzle Tool to tighten it snugly (not too tight!).
• If the nozzle seems damaged or worn, replace it using one from your Nozzle Set.

Filament won’t stay on the surface

Solutions:

• Before extruding, press the nozzle firmly onto your surface (paper or DoodlePad) for a few seconds—this helps the filament “anchor.”
• Maintain a steady, continuous motion as you doodle for best adhesion.

Jam inside the pen

Solutions:

• Set the pen to the proper filament temperature and wait for the light to indicate readiness.
• Carefully unscrew the hot nozzle with the Nozzle Tool.
• Press Reverse, then insert the Unblocking Tool from the nozzle end to gently push out lodged filament.

Warning: The nozzle and tool may be hot—use caution and allow them to cool before handling.

Filament won’t reverse/unload

Solutions:

• Ensure the pen has reached Blue/Green heat before pressing Reverse.
• If filament remains stuck, remove the maintenance cover and pull the strand out by hand.

Pen stays red and doesn’t heat up

Solutions:

• Confirm you’ve selected a filament type and speed—the pen will not heat until both are set.
• Heating should take ~60–90 seconds. If it remains red, power cycle the pen (Off → On).
• Still red? Contact help@the3doodler.com.
