[cadcam]

Billy are you still working for Ernie and the NTMA or on your own now?

Brian make the botton of your code look like this :

 

G91G28Z0;

G0G90Y10.;

MOO;

M99P2;

 

Instead of an M30, it just jumps back to the top and starts over.

Why not just run in format 2?

So far, I have not found any advantage to Format 1.

Just a preference I think. Thats how they run in a shop I work with.

No sense changing what they do.

 

You just stated a problem and I gave you an easy fix.

No move to home when starting or ending a program Format 1 ALWAYS goes home.

If memory serves me right I think G49 will send the Fadal home in Z only and not to the home position. Very helpful when doing tall parts or using the 5 axis indexer on the Fadal.

Ron, you are right that a G49 moves Z up - G49 is length offset cancel , so ,G49Z0 is same as H0Z0.

Format 1 will ALWAYS send the machine to home position at a M2 or M30. there is no way around it other than a branch to prevent it from being read like Hardmill provided.

The benefits to format one are in the way that fixture offsets are applied: In format one, you need a movement to apply fixture offsets ie:

FORMAT 1:

E1 - does nothing

E1X0 - moves to X0 Y and Z do nothing.

 

Format 2:

E1 - moves to current postion (G91X0Y0Z0)of E1 coordinates. so, if you are at E0X.5Y6.Z-2. you will move to E1X.5Y6.Z-2.

Billy...

Robert,

 

I think you have the formats backward.

 

format 1 e1 with move to what it is

 

format 2 e1 won;t produce movement

 

At least my 2 fadal work this way

Phil, you are prolly right...

Been a number of years since I worked on Fadals.

I stand corrected (again)

Once again thanks for all your input. This will be very valuable in my meeting.
