Intro

Following is all of the info needed to get your assembled LulzBot Prusa Mendel 3D printer up and running. This wiki page matches the info found in the instructions sheets you have received with your printer. You will also find additional information here including updates, images, and videos. Please read all of the information found here or in the printed information sheets before unpacking or powering your printer.

Warnings

Read these warnings before unpacking or powering up your printer. This 3D printer is a machine with motorized and heated parts. When the printer is in operation always be aware of all possible hazards.

ELECTRIC SHOCK HAZARD

Never touch the electronics board when the printer is powered. Always power down the printer and completely turn off and unplug the power supply before touching or removing any wires from the electronics board.

BURN HAZARD

Never touch the extruder nozzle or heater block with out first turning off the extruder heat and allowing it to cool for at least 10 minutes. Also do not touch plastic extruding out of the hot end nozzle. The plastic can stick to your skin and cause burns. Also beware of the heated bed which can reach up to temperatures 120C

FIRE HAZARD

Never place flammable materials or liquids on or near the printer when powered or in operation.

PINCH HAZARD

When the printer is in operation take care to never put your fingers in the moving parts including the belts, pulleys, or gears. Also, tie back long hair or clothing that can get caught in the moving parts of the printer.

AGE WARNING

For users under the age of 18, adult supervision is recommended.

Unpacking your 3D printer

1. First, remove the top foam padding. Next, remove the two side smaller foam pads.
2. Remove the bubble wrapped power supply and cords.
3. Holding the top two threaded rods, SLOWLY pull the printer upwards out of the box. The two large side foam pads should fall off when the printer is out of the box.
4. Set you printer on a stable level surface.
5. Using scissors or wire cutters, cut and remove the four ORANGE zip ties. Make sure to not cut any of the surrounding wires or belts.

Initial Setup

1. Your printer has been pre-calibrated and tested; however, after unpacking you will need to double check that everything is in order before you print.
2. You should set your printer on a stable, flat, and level surface large enough for extra spacing around the printer. Make sure your printer work space is clear of anything that could obstruct the movement of the printer. Make sure there are no flammable fabrics or liquids near the printer space. It is also best to not put your printer near a drafty window or air conditioner vent.
3. First check for any nuts or screws that have come loose. If you find anything loose, make sure to tighten it back. You just need snug tighten the nuts.
4. Check that the three mechanical end-stops (they are small lever switches) are aligned to contact with the respected ends. The X-axis end-stop should contact with the side of the x-carriage; Y-axis end-stop should contact with the aluminum bed mount plate; Z-axis end-stop should contact with the bottom of the X-axis idler. If the Z-axis endstop was moved out of place during shipping you may need to readjust the height. Before homing the Z-axis during the first test print make sure the Z endstop is set so the nozzle is sitting 0.2-0.5mm above the print bed when at home.
5. Make sure none of the wires have come unplugged from the RAMPS electronics board. If any wires have come unplugged in shipping or unpacking please see the reference image on the wiki page to find where the unplugged wire(s) needs to be plugged back in.
6. Plug in the USB cable, B plug (squarish plug) side, into the USB receptacle on the printer electronics. Plug the other end of the USB cable, A plug side, into your computer.
7. Make sure the printer power switch is turned off (the circle side should be pushed down). Plug in the green RAMPS power plug from the power supply into the RAMPS electronics. Make sure the screw terminals on the plug are facing up. Now you can plug in the AC power plug from the power supply into an AC power outlet.
