Download the latest release of Cura. http://software.ultimaker.com/
Install it with Reprap > Mendel settings. You will get this dialog box upon launching Cura for the first time.
Access full settings by going to Expert > Switch to Full settings
Go to File – Open Profile, and select BKMM Cura Config.ini (Ask bot monitor for distribution of config file)
Export your mesh file from rhino, with rhino units as Millimeters, as an .stl. All of the default export settings should be fine.
Then drag and drop your model (.stl) into the Cura window.
Change following settings on the left panel as necessary: Fill Density – As %, how solid model will be. Like, if you print a box, 100% fill density will make it 100% plastic, whereas 10% will make the box 90% hollow. I recommend 10% as a default cause it makes prints go faster (it will be a box no matter what, it’ll just be hollow!)
Then right click the Save icon on the top left corner of the blue model preview window (the middle one) and select Save Gcode. Save it to your SD drive.
Insert the SD card into the LCD of the machine. The port is on the left side toward the back of the LCD screen – the sticker on the SD should be facing the machine when inserting.
– Maximum build volume is 7x7x12″ XYZ
– Orient your model so that it starts printing from a flat face, and doesn’t cantilever over the bed too much
– Don’t forget to use the knob to slow down printer speed if the model is complex
1 – Turn on machine
The on/off switch is located on the back right of the machine. Once on, the LCD screen located on the front should glow and produce a readout.
2 – Initiate preheat
Push the LCD knob to display the main menu. Go to Setup > Preheat PLA to heat the machine. You will not be able to remove or insert filament until the machine is heated. Note the temperature readouts displayed on the top row of the LCD screen.
3 – Remove Filament Spool
When the machine extruder has finished preheat, the first temperature readout will read “220/220”. When this is so, you can remove and insert filament into the extruder drive. If there is presentely filament loaded into the machine, you can back it out by pushing the LCD knob, going to Setup > Move Axis > .01mm > Extruder. Turn the knob counterclockwise to eject the filament. After a few revolutions, the filament should exit the extruder.
4 – Insert Filament Spool
Cleanly cut of the end of your filament to produce a flat edge. Load the edge into the small hole located on the top of the extruder. Hold the filament genly pressed as far down as it will go. From the same interface as the end of step three, turn the knob clockwise to load the filament into the extruder. Continue to turn the knob a few revolutions until the filament oozes out of the extruder. If you are loading a different color filament than what was previously loaded, continue to turn until your filament is oozing.
5 – Level the bed
A -Load your glass bed, with painters tape applied to the top, onto the machines central metal tray.
B – Go to Setup > Auto Home. Once homed, for to Setup > Disable steppers to allow the extruder and bed to be gestured freely.
C – With your hands, gently bring the extruder to the center of the glass plate. Without touching the machine, slide a piece of paper between the nozzle and the bed. You should feel slight friction, indicating that the machine is leveled. If it cannot fit, the nozzle is too close. If there is no friction, the nozzle is too far.
D – Note the end stop adjustment screw on the left middle of the machine, pointing down, with a plastic cap on its end. If the nozzle is too close, give it a quarter to a half turn clockwise. If the nozzle is too far, give it a quarter to a half turn counter-clockwise. Repeat from step B until the machine is leveled.
6– Insert SD Card + Send Print
The SD card is inserted into the left side of the LCD interface, with the SD card front facing the machine. When inserted properly, the LCD screen will refresh, and a new menu should be available at the bottom when pressing the LCD knob reading “Make Magic”. From the “Make Magic” menu, click your file name to begin the print. Observe the first few layers of the print ensure that the bed is level, the filament is sticking, and that the print begins to correspond to the file you’ve created.
8 – Remove print + Unload Filament
Once finished, the machine will move the extruder out of the way of the bed, allowing you to take your print off the machine. For the courtesy of others, remove your filament from the machine once you are finished printing.
– The maximum build volume XYZ is 7 x 7 x 12”. Make sure to pack away your filament spool properly! Cheaper filaments, as well as filament spools that have been significantly unwound from improper keeping, are subject to tangling. Tangled filament can interrupt and ruin prints. Thread the loose end of the filament into a hole in the side of its plastic spool and pull tight every time you remove filament from the machine.
