HELLO!

When moving to the home position after the cycle,

M09
G28 G91 Z0.
G90
G49
G28 G91 X0. Y0.
G90
M30
%
It's being printed like this.

I would like to change this so that G53 G91 X700 Y-30 can be output from G28 G91 X0.Y0. Help me.

I am sorry that I am not good at English

Hi,

Which post processor do you use? Some post processors has options for changing home positions. Modifications are required for post processors without this feature.

I changed it the same way.
M09
G28 G91 Z0. -----> G53 G91 Z0.
G90
G49
G28 G91 X0. Y0.
G90
M30

It only changes like this.

Okey. To change that, we can override the G28.

• In the "define home positions" section of the post, you must enter the values you mentioned in the first post (X700, Y-30).

• Then let's force write G53 instead of G28 output.

• Also, let's set the "safePositionMethod" value to G53 so that G53 is selected as the standard.

• That's all.

For example, I edited a Fanuc post. You can also look at the attached file.
