G-code preview and simulation in 3D Printing - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to start the G-code preview by loading the file.

3D Printing

preview.load_file('[1]')

Drag options to blanks, or click blank then click option'

Asettings.cfg

Bmodel.stl

Cgcode.nc

Dcalibration.txt

💡 Hint

Common Mistakes

Trying to load a 3D model file instead of a G-code file.

Using a configuration file instead of a G-code file.

The G-code preview tool loads the G-code file, which usually has the extension .nc or .gcode. Other files like STL or config files are not G-code files.

Complete the code to start the simulation of the loaded G-code.

3D Printing

simulation.[1]()

Drag options to blanks, or click blank then click option'

Astop

Bstart

Cpause

Dreset

💡 Hint

Common Mistakes

Using stop() instead of start(), which ends the simulation.

Using pause() which only temporarily halts the simulation.

To run the G-code simulation, you use the start() method. Other methods like stop or pause control the simulation differently.

hard

Fix the error in the code to correctly set the simulation speed.

3D Printing

simulation.set_speed([1])

Drag options to blanks, or click blank then click option'

A5

B'fast'

Cspeed

Dtrue

💡 Hint

Common Mistakes

Passing a string like 'fast' instead of a number.

Passing a variable name without defining it.

The speed should be set as a numeric value representing the simulation speed multiplier. Using a string or boolean will cause errors.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps layer numbers to their heights if the height is above 0.2mm.

3D Printing

{layer: [1] for layer, height in layers.items() if height [2] 0.2}

Drag options to blanks, or click blank then click option'

Aheight

B<

C>

Dlayer

💡 Hint

Common Mistakes

Using the layer number as the value instead of height.

Using < instead of > in the condition.

The dictionary comprehension maps each layer number to its height only if the height is greater than 0.2mm. So the value is height and the condition uses >.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps tool names in uppercase to their speeds if speed is at least 50.

3D Printing

{ [1]: [2] for tool, speed in tools.items() if speed [3] 50 }

Drag options to blanks, or click blank then click option'

Atool.upper()

Bspeed

C>=

Dtool

Attempts:

3 left

💡 Hint

Common Mistakes

Using the tool name without uppercase.

Using > instead of >= for the speed condition.

The dictionary comprehension uses the tool name in uppercase as the key, the speed as the value, and filters speeds greater than or equal to 50.
