💡 Hint

Common Mistakes

Using G91 instead of G90 for absolute positioning

Confusing G92 with coordinate system setting

G91 sets the machine to relative positioning, but G90 sets it to absolute. Here, the correct code is G90.

💡 Hint

Common Mistakes

Using G90 which is for absolute positioning

Using G92 which sets the coordinate offset

G54 is the standard code to select the first work coordinate system in CNC programming.

Fix the error in the code to set the coordinate offset at X=10, Y=20.

CNC Programming

G92 [1]10 Y20 ; Set coordinate offset

💡 Hint

Common Mistakes

Using Y before 10 instead of X

Omitting axis letters

G92 sets the coordinate offset. The correct axis letter before the value 10 is X.

4fill in blank

hard

Fill both blanks to set coordinate offset at X=10 and Y=20 correctly.

CNC Programming

G92 [1]10 [2]20 ; Set coordinate offset

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

💡 Hint

Common Mistakes

Swapping X and Y

Using Z or A instead of X or Y

G92 sets coordinate offsets. X10 and Y20 set offsets on X and Y axes respectively.

5fill in blank

hard

Fill all three blanks to create a coordinate system offset dictionary in Python for X=10, Y=20, Z=5.

CNC Programming

offsets = { [1]: [2], [3]: 20, 'Z': 5 }

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

💡 Hint

Common Mistakes

Using numbers as keys without quotes

Wrong values for offsets

The dictionary keys are axis names as strings. Values are their offsets. Here, X:10, Y:20, Z:5.
