💡 Hint

Common Mistakes

Confusing under-extrusion with over-extrusion.

Choosing 'feeds too much' instead of 'feeds too little'.

Under-extrusion means the printer feeds too little filament, causing gaps or weak prints.

💡 Hint

Common Mistakes

Confusing over-extrusion with under-extrusion.

Choosing 'feeds too little' instead of 'feeds too much'.

Over-extrusion means the printer feeds too much filament, causing blobs or rough surfaces.

3fill in blank

hard

Fix the error in the sentence describing a cause of under-extrusion.

3D Printing

A common cause of under-extrusion is a [1] nozzle that blocks filament flow.

💡 Hint

Common Mistakes

Choosing 'clean' which would not block filament.

Confusing 'wide' with blockage.

A clogged nozzle blocks filament flow, causing under-extrusion.

4fill in blank

hard

Fill both blanks to complete the sentence about fixing extrusion issues.

3D Printing

To fix under-extrusion, check the [1] and adjust the [2] settings.

💡 Hint

Common Mistakes

Choosing 'bed' which relates to print surface, not extrusion.

Confusing speed with temperature settings.

Checking the nozzle for clogs and adjusting temperature can help fix under-extrusion.

5fill in blank

hard

Fill all three blanks to complete the dictionary comprehension about extrusion checks.

3D Printing

checks = { [1]: [2] for [3] in ['nozzle', 'temperature', 'speed'] if [2] != 'optimal' }

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

A'component'

B'status'

Ccomponent

D'optimal'

💡 Hint

Common Mistakes

Using string literals instead of variable names for loop variable.

Mixing up keys and values in the comprehension.

This comprehension creates a dictionary of components and their status if the status is not 'optimal'.
