First try pushing your plastic into the pen. Push gently to ensure it engages with the gears and gets gripped properly. If the strand of plastic inside the pen is not long enough for you to grip or push by hand, you can remove the cover and edge it forward from there.
Pressing On Surface
Probably the most common question we get is related to this. If you are finding that the plastic won’t hold to paper, or goes off in random directions, don’t worry! The solution is very simple. Push your 3Doodler pen’s nozzle firmly onto the paper and allow the plastic to extrude for a couple of seconds, then lift the 3Doodler’s nozzle off of the paper. The extra downward pressure will help your extruded plastic stick to the paper. We call this “anchoring” your plastic.
Finishing and Tips
Your PRO+ comes with a full Nozzle Set, and the case that holds the nozzles is also the tool that you will use to remove/apply your nozzle.
To change the nozzle, first make sure the pen is turned on and fully heated up (wait for the light to turn Blue). Remove the nozzle by turning the nozzle tool counter-clockwise. Do not touch the nozzle, as it is extremely hot! Insert the new nozzle into the nozzle tool with the screw/base facing outwards. It is okay for there to be residual filament inside the nozzle.
If the pen has gone to sleep, press the feed button so that the pen heats up again. Once the pen is hot again and reaches the target temperature, screw the nozzle onto the pen by turning the nozzle tool clockwise. Make sure the nozzle is screwed on firmly, but don’t force it!
It’s important that you don’t over-tighten the nozzle, and equally important to keep the nozzle removal tool centered, so as to avoid damaging the threaded tip.
Using the Smoothing Tool
The smoothing tool can be used to smooth out rough spots or edges, to remove excess filament from your Doodles, or to create contours or textures. While the 3Doodler PRO+ is unplugged and cool, slide the Smoothing Tool onto the nozzle of the 3Doodler PRO+.
Turn on the 3Doodler PRO+, selecting the temperature setting appropriate for the filament that you are extruding. When done, turn off the 3Doodler PRO+ and allow it to cool (for approximately five minutes) before removing the Smoothing Tool.
Using the Mini DoodlePad
The 3Doodler PRO+ comes with a mini DoodlePad. This a transparent piece of plastic with a grid on it. The DoodlePad can be used alone, or as an overlay. For best results, when using WOOD, Bronze, Copper or FLEXY, use the backside only. ABS, PLA, and Nylon work best on the front side.
