Display—Shows all the necessary information for setting up and using your 3D printer.
Sliderblock—When you inspect the rods of the gantry, and in particular how they fit in the sliderblocks, there should be no gap between the rod and the sliderblock. If there is a gap, there’s a possibility the rod will work itself loose from the sliderblock. Hold the sliderblock in your hand and apply pressure to push the rod in. You should hear a click. Approximately every 8 weeks, apply a few drops of sewing machine oil on these rods to keep everything smooth. Don’t use WD40, use sewing machine oil.
Spool holder— The plastic piece that holds your filament. It attaches to the back of the printer. To install, insert the top part in the hole at the back of the Ultimaker 2+. Push the spool holder down until it snaps into place.
Power socket—Plug one end of the power cable into the power brick and the other end into the wall socket. Next, connect the power supply to the Ultimaker 2+. The flat side of the cable needs to point upwards. After this, you can turn the Ultimaker 2+ on. Be aware that with the Ultimaker 2 Go the orientation of the flat part is reversed and is facing down.
Note: Before connecting the power supply, make sure the power switch on the Ultimaker 2+ is in the “off” position.
USB Socket—Periodically, a new Cura version is released, including a new firmware version. Make sure to install the latest version of Cura and firmware once available in order to stay up to date. The latest version of Cura can always be found at Ultimaker: software. To install the latest firmware on your Ultimaker 2+, you will need to connect your printer to your computer with a USB cable.
Power switch— Before setting up your printer and connecting it to your power supply, make sure the power switch is in the “off” position. Only use the power supply that came with your Ultimaker 2+.
Geared feeder—An improvement to the Ultimaker 2 feeder that developed out of community feedback. This feeder has higher torque and better control of filament feed than the previous model. In order to guide the filament properly through the feeder into the Bowden tube and print head, it is important that the tension on the feeder is set correctly. If the tension is too high, it means that the knurled wheel of the feeder will dig into the filament, through which it flattens or gets stuck. This is called grinding. To prevent grinding of the filament, ensure that the white insert clip at the right side of the feeder is set in the middle. When you use other materials than materials delivered by Ultimaker, you might have to adjust the feeder tension slightly for the best results.
