Postbuilder Question, ZW parallel axis.

[Jaydenn]

Hi all,

I'm trying to get the ZW axis to work in my post.

let me start by quoting a snippet of the "how to" instructions from postbuilder...

This procedure will be executed automatically at the start of program and anytime it is loaded as a slave post of a linked post.
You will need to add the following line (without the #) to the top of the custom command PB_CMD_before_motion.

#PB_CMD_zw_before_motion


Now, my question is this...
There is no "PB_CMD_before_motion" command in the post...
As far as I can tell this is a process contained in the ugpost_base.tcl.

Is this the intention? that I edit the ug base post? The base post that the help file explicitly states DO NOT EDIT.

Am I missing something?

I have noticed this too. If I create a new post using the Generic Controller then I don't get the custom command PB_CMD_before_motion

If I use a Library controller then the command is added to the post.

No I don't think it is the intention to edit ugpost_base, PB_CMD_before_motion isn't in ugpost_base but is checked to see if it exists in your post tcl file in MOM_before_motion which is in both the post tcl file and ug_post_base. The one in ugpost_base is overridden by the one in your post as the last one read is the one that is used. I created a new post 3 axis with generic controller and it was in there John. But at a glance you should be able to just create the command and then insert the call into it.

Cute.

Thanks for pointing that out John. I did what you said, and seeing that the "before_motion" default command is empty, I'll just make my own.

Looks like the instructions should indicate to make a custom command if one doesn't exist.
