Power on your LulzBot Mini 3D Printer.
Connect your printer to your computer using the USB cable.
Press the Print Monitor control tab in the top right of Cura LulzBot Edition.
Verify USB Device Available, as shown in image.
Under "Manual Control" click Connect.
Click the home icon below "Position Z".
Power off and unplug the power cord from the rear of the printer.
Unplug the USB cable from the front of the printer.
Using your 2.5mm driver, unscrew the two M3 screws that secure the connector cover on the X-axis carriage, located on the top of the cover.
Using the scissors, cut the two zip ties that secure the harness to the carriage.
Lift the connector away from the X-axis carriage.
Unplug the tool head connector from the wiring harness.
The tool head is attached with three screws. The print surface can be damaged if the tool head is allowed to fall onto the print surface. With one hand, support the tool head while following removal steps below.
Using the 4mm hex key, unscrew the three M5 screws securing the tool head to the X-axis carriage. Remove the bottom screw first, followed by the remaining two screws.
Remove the tool head from the printer by lifting the tool head away from the printer.
Note: In previous versions of our tool heads, the Esteps (Extruder Steps Per Unit) were listed along the back of the tool heads for the customer to update. For the new Aerostruder tool head however, the Esteps are now set up within the firmware, and no manual updates are required.
Press the Aerostruder onto the X-axis carriage, aligning the tab with the cutout on the back of the new tool head.
Secure it to the X-axis carriage by loosely screwing in the top two screws. Leave the top two screws loose.
Install the last screw into the bottom of the X-axis carriage and fully tighten.
Tighten the top two screws.
Pull foam off of 16-pin connector piece.
Connect the two 16-pin connectors, making sure to match them based on the pins in the connector.
Cover the connector with the connector cover and attach it to the X-axis carriage using the two M3 screws and the 2.5 mm hex key.
Channel the wires together going to down the vertical pathway on the cover mount, and try not to pinch any of the wires when securing the cover. Slide down carefully into place, and hold while screwing in.
Install the latest version of Cura LulzBot Edition. It is important to have the LulzBot Edition of Cura, as it has preset machine configuration profiles built into it.
Cura LulzBot Edition is available from http://LulzBot.com/Cura.
Plug in your LulzBot Mini 3D printer to the power supply and power on your 3D printer.
Once powered on connect your 3D printer to your computer using the USB cable.
Open Cura LulzBot Edition.
Power on the printer.
Select Settings dropdown > Printer > Add Printer
Select LulzBot Mini Aerostruder, and click Add Printer.
Power on the printer.
Select Settings dropdown > Printer > Manage Printers
Confirm the LulzBot Mini Aerostruder is selected, and click Upgrade Firmware.
Select Automatically Update Firmware.
After the firmware update has been completed, open Console by selecting "Print Monitor" tab > "Console". Clicking on the Console button opens a window for sending G-code commands directly to the printer.
To ensure the proper settings, type M502 in console and select "Send Command".
Note: In future Cura LE versions, this will not be needed.
To ensure the proper settings are saved, type M500 in console and select "Send Command".
Select Print Monitor Control Tab in top right corner.
Insert temperature as 205°C for Extruder 1. 205°C is the removal/print temperature for PLA (factory filament left in the tool head from calibration).
Select Heat Extruder.
Note: Always heat the hot end to extrusion temperature before attempting to remove filament as this will prevent clogging or jamming in the filament chamber.
Once hot end has reached the extrusion temperature of 205, remove test filament used during factory calibration by manually winding gear as shown in image. You can also do this by entering 60 for the Extrusion amount in Cura and clicking Retract.
Once filament has retracted 60 mm, squeeze idler inwards, and pull the filament out. You may need to loosen the idler slightly by turning the silver idler wheel clockwise.
Tighten the idler by turning the silver idler wheel counter-clockwise if loosened.
Note: If filament other than PLA is being used, refer to page 35 of the LulzBot Mini User Manual for recommended hot end temperatures. Repeat Step 14, entering in appropriate temperature value within range suggested for chosen filament before loading filament.
Load your filament into Extruder 1. Squeeze the idler arm inward and insert the filament directly downwards.
Rotate the gears by hand as shown in the image to help pull the filament into the tool head.
Purge factory filament by continuing rotating gear by hand as shown in image until extrusion transitions into your filament of choice.
You've now finished installation and are ready to start printing with flexible and rigid materials using your LulzBot Mini Aerostruder! Try performing a test print, such as the Rock2pus.
