If you are experiencing a flashing red light with your 3Doodler Start+, please contact our Customer Service team for assistance.

A solid red LED indicates the pen is on and warming up. The LED will change to solid green or solid blue once it’s ready for use.

After several minutes of being switched ON without engaging the motor, your pen will go into “standby mode.” The heat will cut off, and the LED will stay red until the device is made active again.

Reactivate the device by single-clicking the button or by turning the pen OFF and then ON again. If your LED remains red after this, please contact our Customer Service team.

Occasionally, when you get to the end of one strand, extrusion slows noticeably. Insert a new strand into the back of your 3Doodler pen.

If it still extrudes very slowly (or not at all), try giving the new filament a little nudge downward. This should resolve the issue.

Jams can occur occasionally and may have different causes.

While your pen is feeding forward, firmly push the filament into the feeding port. If this does not resolve the issue, please reach out to us for further assistance.

Jams can occur occasionally and may have different causes. Most often, jams occur from reusing filament without trimming the ends.

Here are some tips to help you avoid jams.
Check your filament: Make sure it’s bendy and flexible. Filament that is brittle or breaks easily should be discarded.

15-second rule: Wait 15 seconds after extrusion stops before reversing out a strand.

Trim those ends: Always trim off the melted end of filament before reinserting it into the pen.

Doodle it out: If you can’t reverse a strand out, or you will be putting your doodler away for a bit, always extrude all remaining filament inside the pen.

Begin by fully charging your 3Doodler Start+ for 30 minutes to 1 hour.

Once charged, turn the pen on. The light should change from Solid Red to Solid Green. This typically takes about 30 seconds but may take up to two minutes.

If the pen remains idle for too long, it may cool down as a safety feature and enter standby mode. If the LED has not turned Solid Green after three minutes, please email our Customer Service team.
