Practice - 5 Tasks

1fill in blank

easy

Complete the code to move the machine to its home position.

💡 Hint

Common Mistakes

Using motion commands like G00 instead of specifying coordinates.

Omitting the axis coordinates after G28.

The command G28 X0 Y0 Z0 moves the machine to its home position on all axes.

2fill in blank

medium

Complete the code to set the current position as the reference point.

G92 [1]

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

💡 Hint

Common Mistakes

Using unrelated commands like M06 or M03.

Not specifying the coordinates after G92.

The G92 X0 Y0 Z0 command sets the current position as the reference point at zero for all axes.

3fill in blank

hard

Fix the error in the code to correctly move the machine to the reference point.

💡 Hint

Common Mistakes

Using G92 or G28 directly after G00 without coordinates.

Using spindle commands like M05 instead of motion commands.

The command G00 X0 Y0 Z0 moves the machine rapidly to the reference point coordinates.

4fill in blank

hard

Fill both blanks to set the machine home and then move to the reference point.

💡 Hint

Common Mistakes

Using M30 which is program end instead of coordinates.

Mixing motion commands and coordinate values incorrectly.

First, G28 X0 Y0 Z0 sends the machine to home. Then, G00 X10 Y10 Z10 moves it rapidly to the reference point at coordinates 10,10,10.

Fill both blanks to define a new reference point and move the machine there.

💡 Hint

Common Mistakes

Adding coordinates after M30 which is not needed.

Using different coordinates for setting and moving to reference point.

G92 X5 Y5 Z5 sets the current position as reference at 5,5,5. G00 X5 Y5 Z5 moves the machine there. M30 ends the program; no extra code needed after it.
