G40 & G41, how to output individually

[mroy0404]

Hi guys

Can one of you guys help me out here, im using Mastercam X3 lathe with post processor MPLmaster. When I use wear in my settings G40 & G41 get output on lines with X an Z. How can I have the code come out of this post processor with the G40 and G41 on a line individually.
I have attached an example of my program below.

is there any special reason for the G40 and G41 on a line individually.

I never output those codes on a line individually even when I get CRC interference alarm.

usually the G41/G42 should pop-out on the last movement before the tool touch the part, the same for the mill....
using canned cycles that same movement should be higher than the cutter comp.

lead-in/extend/starting point would work I guess,

You'll have to edit your post to get that output.. Make a backup copy of it before you do any changes. I don't have the post your using but this is a section of a lathe post I did have.

The following can be used to change the g code output. To add things to each line or seperate things too. ex. move g codes, seperate axis movements or even add things to a line.

Anything that you put in "quotes" in the post will show up in the program as that exactly, if you want to add something to each line.



In this post psccomp is the cutter comp variable, you can find that by looking at the section of the post near the top that defines the variables.

Then search for that variable. Anything that starts with pbld and ends with e$ is an output line of g-code. Anything after a # in the post is ignored
