Home Position

[Rory]

I have been programming for a Milltronics Partner with a Centurion V control.

My question has to do with the Home Position and transform toolpath option.

When I post a file without a transform operation, the home position is output.

If I post the same file with a transform operation, the home position is not output.

Is this a problem with the post?

If so can any one tell me where to find it and how to get around it?

Thanks,

Rory

If you are using Subs with multiple fixture offsets in your transform, then the Home Position would not be output because the position will be different.

James,

I'm not using subs or multiple fixture offsets.

In your post, if you can find xh,yh and zh this is where the home positions are output. If you cannot find these variables, put them where you would like them output. Generally they will be found in the lines above or below tool chabges. If you are going to always use home position, then put a "*" in front of the variables like this *xh,*yh and *zhThis will force the variable's output where it is located.

If I were doing it to my post, my line would look like this;

pbld, n, *xh, *yh, *zh, e

n, *t, "M6", e

or like this;

pbld, n, xh, yh, zh, e

n, *t, "M6", e

This should do the trick.

What post processor are you using?

I modified the Fanuc post for the Centurian I and it works with Home position and 'translated' toolpaths.

He said he was using the Centurion 5 Post I think.

I am using a modified version of the Mpcent5.pst.

The fella who was programming before me modified the post and he did'nt keep the best records.

James,

What does the pbld stand for?

Its not defined in the post.

pbld basically means Block Delete/Skip. If you turn on block delete/skip in the operation, then where you see "pbld" a block delete/skip will be input. Your control may not support those so as a precaution I'd probably leave them out.

Hope that helped.

P.S.: In the header of the post (where all the "#" lead the line there is a notres section. You should describe every change you make so that you'll know what you did and when you did it.

P.S.S.: If you make the changes I suggested above, make sure that you indent 1 tab because you cannot have anything but a postblock there.
