💡 Hint

Common Mistakes

Using G40 which cancels tool radius compensation instead of length offset.

Using G41 or G42 which are for tool radius compensation, not length offset.

G43 is the standard G-code command to apply the tool length offset in CNC programming.

💡 Hint

Common Mistakes

Using the wrong offset number that does not match the tool in use.

Omitting the H code which is required after G43.

The H number after G43 specifies which tool length offset to apply. Here, H3 means offset number 3.

💡 Hint

Common Mistakes

Using G42 which is for tool radius compensation right.

Using G44 which is for tool length offset negative.

G43 is the correct command for tool length offset. Other codes are incorrect or used for different functions.

💡 Hint

Common Mistakes

Mixing up G44 which applies negative tool length offset.

Using the wrong H number that does not match the tool.

G43 activates the tool length offset, and H5 selects offset number 5. Z50 moves the tool to position 50 on the Z axis.

💡 Hint

Common Mistakes

Using G44 instead of G43 for tool length offset.

Forgetting to specify the H number after G43.

G43 activates the tool length offset, H1 selects offset 1, and X100 moves the tool to X position 100 before retracting to Z150.
