MakerBot/quiz

 {The programming languages specifically designed to create 3D objects that MakerWare can interpret include: -Perl +openSCAD -ruby -fortan
 * type=""}

{What is the build plate leveled against? -gravity .. leveled with a tiny bubble level +the XY plane the printhead travels on -bottom of the makerbot
 * type="[]"}

{When changing the PLA filament, what should you be worried about? +Not breaking filament off inside the print head +Making sure the nozzle is warmed up -Melting the guide tube -Burning your fingers
 * type="[]"}

{Where can you set the dimensions of your part? +In the software that created the object +In the Makerware software -Can not set the dimensions, just guess -Print different versions until you find the right size
 * type="[]"}

{How is a print job aborted? -Pull power cord -Press the M button +Press the button to the left of the M button -Press the button to the bottom of the M button
 * type="[]"}

{When should the build plate be re-leveled? +After an object is removed +After the tape is replaced -After the filament is changed +After the build plate is manually pushed for any reason +After the makerbot has been moved
 * type="[]"}

{How is the old PLA filament removed? +Through the MakerBot utility menu +Letting stepper motor push the old filament up +Pulling old filament up when told by MakerBot -Pushing down on spring clamp, then pulling old filament up once headed
 * type="[]"}

{What should not be printed? +trademarked, patented stuff +gun parts .. is against Federal Law +Personal stuff -Project related items +Personal Inventions
 * type="[]"}

{How is the new PLA filament inserted? +Through the makerbot utility menu +Pushing new filament until stepper motor grabs it and finishes pushing through nozzle -Pushing down on the spring clamp, then pushing new filament until grabbed by the stepper motor
 * type="[]"}

{Leveling the build plate takes practice. What is the preferred problem to have? +Error in making a gap too large between the nozzle and the table -Error in making the table slope down from left to right -Error in making the table slop down front to back -Error in making the gap between the initial position of the nozzle and the table too small
 * type="[]"}

{What causes the build plate to not be level? +removing objects that have been printed -turning off and on +pushing the build plate around manually
 * type="[]"}

{Lots of little objects all printed at the same time are more of a problem why? +Prints can be messy +PLA warps, print head may click or catch the object and knock it off the table +Problems avalanche, one piece coming off messes up the neighbors
 * type="[]"}

{MakerWare needs files in what format? +STL -3DS -SCAD -X3G -G-code -Ruby +OBJ +THING
 * type="[]"}

{Suppose the printer stops randomly. The print head is too close to remove any material start and over. How should the build platform be moved? +use jog or home controls on the front of the makerbot -push down on the build platform -start printing again and it will move to the correct spot -pull the painter's tape off while platform is in the printer
 * type="[]"}

{What 3D software can save files in STL or OBJ? +123D +3D Studio Max +Sculptris +3Dtin -Sketchup
 * type="[]"}

{What is the preferred normal build surface? +Blue painter's tape -The clear plexiglass surface embossed with the makerbot logo -Double sided tape -Raft -Masking tape
 * type="[]"}

{What causes the nozzle to clog? +PLA burning and turning into ash +PLA being melted twice (cool down, heat up, cool down, heat up without extruding) +PLA covering the nozzle so can not cool properly
 * type="[]"}

{What happens if objects are not placed on the platform in MakerWare? +print nozzle clogs, nobody can print +blob of pla accumulates on the nozzle -nothing much, just doesn't print right -bottom view layers aren't right, but otherwise object prints fine
 * type="[]"}

{Who owns the objects printed? +HCC -person printing -person who created *.xg3 file -nobody and everybody .. everything is free
 * type="[]"}

{There are lots of places where pre-drawn objects can be downloaded and printed. Which are some of them below? +Smithsonian -123D +3D-Warehouse -Makerbot +Thingiverse +Traceparts +OpenSCAD gallery +Archive3D
 * type="[]"}

{What two steps must be done in order to get an estimate of the build time? +Check preview in the advanced options screen -Click on the build time estimate button -Multiply the number of build layers by 0.6 to get minutes +Export to a file and then the preview screen appears
 * type="[]"}

{It is possible to print through a USB cable. Why do we use an SD card? +set up a manual print queue +record information about the print (owner, object/file name, print time, etc) +enable multiple people to share the makerbot +encourage people to create *.x3g files while the makerbot is printing
 * type="[]"}

{When should a raft be used? -Always +When there is very little object contact with the build plate +Tall and skinny objects +High resolution printing ... so the first layer blobs are minimized
 * type="[]"}

{When should someone extrude for 30 seconds? +When the Makerbot has cooled down and sat unused. -Before every print job. -After 10 hours of printing. -Before every other print job.
 * type="[]"}

{Why extrude for 30 seconds? +Clean out any burnt PLA that may be stuck inside the nozzle. +Make sure the PLA spool is not not stuck, kinked or caught on something. +Make sure the PLA comes straight down off the nozzle
 * type="[]"}

{Why is leveling the build plate important? +preventing nozzle from clogging +so objects print correctly +so the nozzle travels above the build plate at a constant distance -so that one can remove objects from the printer when done
 * type="[]"}

{What is the manual print queue for? -Like an normal print queue, first come first served. -It just helps everyone form a line so that everything eventually gets printed. +So that one person doesn't hog the printer for 24 hours. +So that long jobs get printed at night when nobody is in the room. +So that objects can be reprinted if they become popular.
 * type="[]"}

{Why is it mandatory to watch the first layer or raft print? +This is where most of the problems occur +Build plate may be too far below nozzle and doesn't stick to the blue painter's tape +Build plate may be too close to the nozzle and nozzle starts dragging PLA around like finger paint.
 * type="[]"}

{Physically how is the build plate leveled? +There is a level option on the utilities menu of the Makerbot front panel. -Using a tiny bubble level. +Using screws underneath the build plate. +Using a piece of paper or metal shim that is slid between the build plate and the nozzle.
 * type="[]"}

{How does one extrude for 30 seconds? +Makerbot utilites, load filament -Makerbot utilities, extrude -Makerbot utilities, home -Watch print for 30 seconds
 * type="[]"}
