I have the same problem.  I actually came on this site just to see if there was a solution to this.  My system is quite good so that is not the issue.  I also have the same problem opening Word and Excel documents while I have 2 Mastercam sessions open.  You're not alone.  

No it doesn't have any effect on drills or taps. Go select a drill through the drilling operation. You have picked a 11/64 drill, but need it longer. You were happy with the name of DRILL 11/64, but now when you change the length of the tool the drill gets renamed. Same thing with taps and some other tools. Thanks for posting that up, but I have a number and waiting on a fix like others.

It works with drills and taps for me...

Ah ha.  Thanks to In-house Solutions we have a ... well ... solution.

- Exit Mastercam

- Open the stand-alone Tool Manager (You can find this in the start menu under: All Programs, Mastercam 2017).

- Go to: File - Options - General.

- Deselect the "Enable auto-naming for assemblies, tools, and holders" option.

- It takes effect the next time you run Mastercam.

I tried it.  It works.

So this wasn't fixed in the latest patch either...

Why does MC 2017 Change the tool name when you change a parameter such as tool diameter or overall length?

This is new to 2017 and is also frustrating...

Ok K2csq7 I just sent a small sample file now.  In this case the plane changed when I opened a mill MC Group.  I was unable to change it back.

Hi All,

Gcode, thanks for the files. 

 

John D., Please send the file into QC, you can put it to my attention (Keith G.)

 

Thanks, 

How to send to QC?  Is there an e-mail address?

Loading different MC definitions doesn't seem to help...

If anyone has a solution to this please share as it happens in 2017 also.

Thanks,

Drag and drop drill points from one operation to the next.  Really handy after importing operations.  Just click "no" to using current depth so that your linking parameters aren't overwritten. 

Well I just did a check and the new version is now available.  I will see if it resolves the problem.  Thanks for the info. 

How do I get that version?  Programming with the version I am using is like swimming in tar.

Well that's the obvious reason that you are getting different results wouldn't you say?

JParis,

I can see we are running different versions of Mastercam.  I am running version 17.0.17257.0

When I look for updates I am told I have the latest version.

It does seem a little odd.

All maintenance is paid.

It doesn't happen when the file is smaller.  I think it may be once it gets a little larger.  Don't know if that will help.

No . . .X8 all the way

Thanks, K2csq7

ACTUAL FILE.Z2G

Ok I have created a .Z2G file.  How do I upload?

Ok the file is ready.  Being new here I am just not sure how to share this file.  Do I e-mail it or upload it somewhere?

Thanks.

I'll work on making a small sample file.  I can't send you one of my actual work files...

Try this...

If it doesn't make your operations dirty then maybe the problem is with my install.

Select the last operation in your machine group by right clicking...

Select <Edit selected operations> <Edit common parameters...>

In the Edit Common Parameters (Mill/Router) dialogue box select the <Planes> tab.

Change the planes used in that operation to any other plane configuration.

Select <check mark> for that menu.

Select <check mark> for the main menu.

See what happens to your operations.

I am experiencing the exact same problem.  I will just change the plane in one tool-path operation and every operation using that plane in the machine group goes dirty.    

The new "Plane Manager" seems to be quite problematic.  At least we can name our planes using lower-case letters now.  Huge improvement.
