Posting Helical Milling with G2/G3 Motion 1

[FG4608]

Is there a way to get the post to output helical motion with the G2/G3 words where a 'Z' word indicates the pitch?

Ex;

G2 X1.0 Y1.0 Z-.5 I-1. J-1.

Thanks!

Clarification!

The 'Z' word does not really indicate the pitch, but instead the actual Z-level at the finish x,y coordinates...

That is just normal helical output. Nothing special about it.

You need to do a few things to make it work.


In the post;
You need to import a custom command into the post to allow helical output.

Add the "PB_CMD_helix". You don't need to add this to any event... It just needs to be there.

Also make sure that the "Z" word is added to the circular move event. By default it IS, so unless you removed it, it will be there.

In your operation, you need to check that in "machine control" the output is set to "Circular-Perp to TA"

Thats it. Should work.

Awesome, awesome, awesome!

Thanks Jaydenn. I love simple solutions...

One follow up question though?

I'm not sure where it is you are telling me to set the ourput to "Circular-Perp to TA". Could you point me in the right direction please?

Thanks Beforehand!

This is in the "Machine Control" portion of the operation dialog

Hi Jaydenn,

I tried to import this PB_CMD_helix from custom command directory, after import it is not listing inside the custom command list as you showed. Do I need to set any other thing to use import option. No error messages after import.
Using PB 5.0.3, please need help, Thanks

I think the command is actually PB_CMD_init_helix that is inside of that import. check it out. Good luck

Thanks for the reply,
I tried using postbuilder 3.4.1 to import custom command there was no problem, it displays an additional dialog and I could choose ok to import that custom command.
Now my problem is in postbuilder version 5.0.3 unable to import any of the available custom command, Is any one face this kind of problem in postbuilder 5.0.3, please help me.

I am on PB6.0.2.1 but have used 5 and as I know I imported commands in it but I don't think I was importing init_helix. Aas far as I know there wasn't a problem with importing commands in that version, but then again I was really green last year when I was using 5. Oh wait I still am pretty green. LOL. Anyway are you just clicking import in the custom command area? It should come up with a browser window to browse to the command. Maybe someone else knows more about this problem. Sorry I can't be of any more help.
