Trying to replace an Alignment

[cmmuser]

How can I get around this problem?

To be brief, I am attempting to replace my opening manual and DCC alignments to prevent having to re-program a part.

My Original alignment had created a Line for Rotation between two circles. The manufacturing has changed recently leaving these two holes out until a later operation. These two holes were along the X-axis.

The new structure I am trying to build uses the exact same XYZ coordinate structure and is to use a hole at the 12 O'clock position to the machine making my rotation line along the Y-axis. Theoretically, I am telling the machine to use a new line that is 90° to the old line and rotate to the Y-Axis instead of the X-Axis, but the machine thinks I'm out to lunch.

I have answered "No" when the software asked me if I wanted to update all the related features after creating this alignment.

However, the program will not operate at all in DCC. I am getting an "outside of travel limits" error.

Load the old and new alignments for us.

Just before you old alignment, put in a the new one, then delete the old one, and yes, say no to update alignment.

Anytime you go replacing alignments you take your programs life in your own hands. Did you delete the 1st 2 alignments or just go in and edit them. If you deleted them then the next alignment your program comes too does not know were it is. IE recall alignment at top of alignment box.

adding a recall startup alignment after your alignments say NO to update
do your edits and then remove startup and answer NO again.. backup of course

I remember when I started doing this programming stuff and editing alignments was challenging. Here is what you do. Make a back up copy of your program and go nuts, edit away and pay attention to what happens. You will get good at it by doing it and when you frog it up (you will) whip out the back up. Watch your graphics screen (you may have to dynamic rotate) and look for the trihedron. Compare the numbers in your old prg to this edited one. This alignment stuff is tricky for newbies. If you need to post your code here and tell us what you want to do.

highlight and copy all the data below your old alignments (CNTRL C)
Then close program, open a new program, name it whatever you want, build your new alignment, then paste the copied data.
This has worked for me with some success.

Are you using iterative or 321 alignment?
I have a hard time with iterative alignments some times. Either way, you should be able to edit the existing alignment and have it work. Just make sure that what you are telling it is actually possible. eg, use the right hand rule to make sure that you are telling it the correct direction to rotate to. Also, check your line construction or order of picking the circles. I am not sure of your skill level so I don't want to get too generic. But, sometimes we don't notice the little things. Just today, it took me a couple minutes to figure out that I had accidentally changed the probe in the program and didn't understand why my surface hits were off by 1 mm. It was the diff between a 2 and 4mm ruby. If I wasn't measuring everything with the same tip angle it would have been more obvious.

I found the best way was the same as JTNOTCH uses. Just create your new alignment and then copy and paste the rest of the prog in. Never had a problem doing it this way.
