💡 Hint

Common Mistakes

Using M04 which starts spindle counterclockwise.

Using M05 which stops the spindle instead of starting it.

M03 starts the spindle rotating clockwise, which is standard for face milling.

💡 Hint

Common Mistakes

Setting spindle speed too low or too high for the material.

Confusing spindle speed with feed rate.

S1500 sets the spindle speed to 1500 RPM, which is typical for face milling.

Fix the error in the code to move the tool to the start position at X0 Y0 Z5 safely.

CNC Programming

G0 X[1] Y0 Z5 ; Rapid move to start position

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

💡 Hint

Common Mistakes

Using X5 or X-5 which moves tool away from start position.

Confusing Z and X coordinates.

X0 moves the tool to X zero position. Using 0 is correct to start at origin.

4fill in blank

hard

Fill both blanks to create a loop that moves the tool in a square path for face milling.

CNC Programming

G1 X[1] Y[2] F100 ; Linear move with feed rate

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

💡 Hint

Common Mistakes

Swapping X and Y coordinates.

Using zero for both X and Y which does not move the tool.

Moving to X50 Y0 starts the first edge of the square path.

5fill in blank

hard

Fill all three blanks to complete the face milling program with spindle start, speed, and tool retraction.

CNC Programming

M[1] ; Start spindle
S[2] ; Set speed
G0 Z[3] ; Retract tool safely

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

💡 Hint

Common Mistakes

Using M05 which stops spindle instead of starting.

Setting speed too low or too high.

Not retracting tool before rapid moves.

M03 starts spindle clockwise, S1500 sets speed, and G0 Z5 retracts tool safely.
