💡 Hint

Common Mistakes

Using the wrong X coordinate for the start point.

Using G01 instead of G00 for rapid positioning.

The tool must move rapidly to X=10 to start the contour milling at the correct position.

medium

Complete the code to mill a straight line segment along the Y-axis.

💡 Hint

Common Mistakes

Using the wrong Y coordinate for the end point.

Forgetting to specify the feed rate.

The line segment is milled from Y=0 to Y=20 at X=10 with feed rate 100.

3fill in blank

hard

Fix the error in the code to correctly mill the next line segment back to X=0.

CNC Programming

G01 X[1] Y20 F100

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

💡 Hint

Common Mistakes

Using the wrong X coordinate causing the tool to move incorrectly.

Omitting the feed rate.

The tool must move back to X=0 at Y=20 to complete the contour segment.

4fill in blank

hard

Fill both blanks to complete the code for milling the final line segment down to the start Y position.

CNC Programming

G01 X[1] Y[2] F100

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

💡 Hint

Common Mistakes

Using incorrect coordinates for the final move.

Forgetting the feed rate.

The tool moves to X=0 and Y=0 to finish the contour milling at the start point.

5fill in blank

hard

Fill all three blanks to create a dictionary mapping line segment start points to end points.

CNC Programming

segments = { [1]: [2], [3]: (0, 0) }

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

A(0, 0)

B(10, 0)

C(10, 20)

D(0, 20)

Attempts:

💡 Hint

Common Mistakes

Using incorrect coordinate pairs.

Mixing up keys and values.

The dictionary maps (10, 0) to (0, 20) and (10, 20) to (0, 0) representing line segments of the contour.
