Hey Gang...

 

Having some problems with the 4th Axis output on our Haas.

And I also don't know why it is outputting an R value as well. This is using Rotary Axis positioning. I have a little experience editing posts, but this one is beyond me. This is using X3. Everything seemed to work fine in X2 MR2. Thanks for any help.

The header of the post says it's a "mpfan". I read the post about updating the parameters, but I couldn't find those parameters in the post.

[TECHSERV]

Weird. This is what I get in X2 MR2.

This is exactly what I want. What is the difference?

[HEED]

the difference is one's right and one's wrong ? Just a thought...

[TECHSERV]

Ha. Cheers. The 2nd one is right. The first one is bad. I've determined that it's something between X2 and X3 as both programs use the same post. Any thoughts?

[TECHSERV]

I did the post debugger. There was nothing there about the rotary. Where the canned cycle starts, the post gets the pdrill string, and then the only other thing before the G80 is a pdrill_2. I'm at home now and tried with the generic Haas post (my email wouldn't let me download my post...) and I was still getting bad code, nearly identical to the first bad code, which tells me that it wasn't the post. I've uploaded my file to the FTP site. In the X3_Files folder, the zip to go is called "4thaxistest". Thanks

[TECHSERV]

OK. Starting to get a little frustrated. Here's where I'm at: I tried changing every conceivable option in Mastercam to see if it would change. It didn't. I found that the letter R that is out put with the rotary move is some sort of retract or clearance value. Technically, R is from the refht_a in the post. It's like after the first canned cycle line, it completely ignores what to do next. It starts it's own canned cycle with the tool feeding to -.585 in Z and retracting to infinity. This file was not imported from X2. I simply made the same part in both programs. In X2 it works, but not in X3. Any ideas?

 

Thanks,

 

Steve

No thoughts or words of encouragement from anyone?

[TECHSERV]

Hi Colin,

 

The file is on the FTP site. In the X3_Files folder, it is called 4thaxistest. I will post the X2MR2 Z2G (the correct one) as well.

 

Cheers,

 

Steve

[TECHSERV]

Ok. The 2nd one is there now. It is called 4thaxistestX2. Still in the X3 Files folder.

[TECHSERV]

Hi Colin,

 

Thanks for your help. I did email QC this morning, and got the following reply:

 

"This appears to be an issue logged as cnc00038652 but is now fixed in the Maintenance update of X3. There appears to be no work around for the time being."

 

So I guess I'll wait for the maintenance update. Bummer. Thanks again.

 

Cheers,

 

Steve

That's a good way of doing it. I found I could do it too with Transform rotate toolpath.
