Using the Control Box to Manually Move Along the Axes

There may be times when you would like to move the Hot End to a different position, in the X-direction, Y-direction, or the Z-direction, or possibly in all three directions. Follow this procedure to manually control the location of the Hot End. The last step shows you how to manually extrude molten plastic from the Nozzle.

  1. Make sure the printer is turned on and the Orange Control Box is in the HOME screen. If the printer is off, turn it on and wait for the startup procedure to finish. Proceed when the HOME screen appears.
  2. On the HOME screen, highlight the “Control” box by turning the wheel. When “Control” is highlighted, select it by pushing in the wheel.
  3. Turn the wheel to highlight “Move Axis” and select it by pushing the wheel. You may now highlight and select any of the three directions to manually move the Hot End in that direction.
  4. Let’s move the Hot End in the X-direction. Turn the wheel to highlight “Move X” and select it by pushing the wheel. You will notice that the number to the right of the words “Move X” turns orange in color when selected. This number indicates the location of the Fan/Hot End assembly along the X-Axis. The number 180 represents the farthest position to the right along the X-Axis, and the number 0 represents the farthest it can travel to the left along the X-Axis (it is possible to go a little further than 0 to negative values). Go ahead and slowly turn the wheel so that the assembly moves in the X-direction. After you have gone a short distance in one direction, turn the wheel the opposite way should make the assembly in the other direction.
  5. Now, let’s move the Hot End in the Y-direction. You might remember that the Y-Axis behaves differently than the X-Axis behaves. Instead of actually moving the Hot End, the Metal Plate moves back and forth while the Hot End remains stationary. If the number to the right of “Move X” is still orange, push the wheel to deselect “Move X”. The number should now be black. Next, turn the wheel to highlight “Move Y”, and select it by pushing the wheel. You will notice that the number to the right of the words “Move Y” turns orange in color just like the number next to “Move X” did earlier. This number indicates the location of the Metal Plate along the Y-Axis as it moves beneath the Fan/Hot End assembly. The number 180 represents the farthest position toward the front of the 3D Printer the Metal Plate can move along the Y-Axis, and the number 0 represents the farthest it can travel toward the back of the 3D Printer. Like you did before with moving in the X-direction, go ahead and slowly turn the wheel so that the assembly moves in the Y-direction. After you have gone a short distance in one direction, turn the wheel the opposite way should make the assembly in the other direction.
  6. Now, based on what you learned about the X- and Y- directions, try to move the hot end in the Z-direction. CAUTION: If the Hot End is already close to the Metal Plate, don’t move it further downward. Moving the Hot End too far down in the Z-direction will cause the Nozzle to crash into the Metal Plate. If you do mistakenly cause the Nozzle to crash into the Metal Plate, it probably won’t cause permanent damage, but it’s best to avoid crashing the Nozzle. Turning the wheel clockwise will make the Hot End go in the upward direction (when the Hot End is moving upward, the number to the right of “Move Z” will increase). Turning the wheel counterclockwise will make the Hot End move downward—again, be careful not to crash the Nozzle into the Metal Plate. After you have moved the Hot End in the Z-direction back and forth, position the Hot End so it is about half way up the Z-Axis. What number should appear to the right of “Move Z” if it is exactly half way up?

Now, we’re going to test the Extruder, and manually push some melted plastic out of the Nozzle.

  1. Select “Move E” from the list of choices on the Move Axis screen—you will notice the words “Low temp” to the right. “Low temp” indicated that the Nozzle is not yet hot enough for extruding. Once you have selected “Move E”, a list of different types of plastic printing material appears.
  2. Rotate the wheel until PLA is highlighted. Push the wheel to select PLA (PLA is the type of plastic we are using here). After selecting PLA, you will be taken back to the Move Axis screen, and you should see at the bottom of the LCD two blinking numbers. The one on the right (215) is the target temperature that the nozzle has to heat up to for the plastic PLA to be pushed out. The number on the left is the actual temperature of the nozzle, and it should be increasing. It will stop increasing when it gets close to the target temp of 215.
  3. Highlight “Move E” (there should now be a black-colored “0” to the right), and select again by pushing the wheel. The 0 should turn orange in color. At this point the wheel can be turned clockwise to cause plastic to be pushed out of the nozzle. This process is called extrusion. Turn the wheel slowly in the clockwise direction, and be patient. The plastic will start to be extruded out of the nozzle. You might notice that the plastic can get bunched up at the nozzle opening. That’s OK, just keep turning the wheel slowly and the plastic will eventually fall downward. As you keep turning the wheel, you should have a continuous line of molten plastic coming out of the nozzle. Go ahead and extrude PLA in this way for a while—you should see an interesting little pile of PLA forming on the Metal Plate below.
  4. When you’ve extruded PLA to your heart’s content, deselect “Move E” by pushing the wheel, rotate the wheel to “Cooldown”, and select by pushing the wheel again. There should be two flashing numbers at the bottom of the LCD: the one on the left is the nozzle temperature, and the one on the right is the Metal Plate temperature. They both should begin to go down since you have given the “Cooldown” command. You can always see the Nozzle and Metal Current Plate temperatures from this Move Axis screen.
  5. The extruded plastic has probably coiled up in a pile on the Metal Plate. You can remove this by using a pliers to pull it from the Metal Plate. The line of plastic still attached to the nozzle will also get pulled off with the pile on the Metal Plate.
  6. Rotate the wheel so that “Return” at the top of the screen is highlighted, and push the wheel to go back to the previous menu. Highlight and select “Return” again to get back to the Home screen.
