💡 Hint
Common Mistakes
Using a negative number for spindle speed.
Using letters instead of numbers.
✗ Incorrect
The spindle speed is set with S followed by a positive number. 5000 is a valid speed.

💡 Hint
Common Mistakes
Confusing X and Y values.
Using zero instead of 10.
✗ Incorrect
The command moves the tool to X=10, so 10 is the correct value.

💡 Hint
Common Mistakes
Using letters instead of numbers.
Using negative numbers.

💡 Hint
Common Mistakes
Swapping feed rate and spindle speed values.
Using too low spindle speed.
✗ Incorrect
Feed rate (F) is 500 and spindle speed (S) is 3000 for proper machining.
5fill in blank
hardFill all three blanks to create a dictionary of tool names and speeds for CNC.
CNC Programming

💡 Hint
Common Mistakes
Using numbers as keys instead of strings.
