new to 5 axis question.

[cobra95kev]

I placed a file on the FTP called kev5FLOW.Z2G

 

It is a simple 5 axis flow cut output to a 4 axis.

I am using an MPmaster based makino post and it keeps exceeding my B-axis rotary limits going over 360 and it errors out when I try to post it. Can someone give me a clue?

 

Thanks alot,

[HEED]

I am pretty new to the whole 5ax thing too, I am interested in a(n) application like this to be solved so I can see how it happened...

Pretty simple you set the Machine Def up to a limit of 360 degrees. Then you did not change the continuous axis type to signed 0-360 you left it at signed continuous which mean you have unlimited, yet you limited it to 360 in the deg limits so one has ot match the other. One other thing if you use a filter on this operation of .00005 it will take the 7mb and turn into .5mb and produce the same quality part.

Thanks Ron,

I will do it in the morning.

 

 

Have a good one.

[cobra95kev]

Ron or anyone else,

 

I edited the machine def as Ron suggested and the output looks right now except for these extra minus signs?

Wierd huh?

[Post dept]

That's a good one, looks like a signed direction B axis which is causing those issues, or at least that's how your post has been setup. May want to contact your reseller to help you out with that one!

 

Chris

[Ron Branch @ Verisurf]

Chris it is a MPMASTER post he is using. I am stumped as to what is causing it.

[cobra95kev]

I am a little hesitant to bother anyone further with this because I have made some edits to the post my reseller sent me and they could be the cause of this.

 

 

But if someone is bored and wants a copy of the post I jacked with I would be happy to send it to them.

AHA!!

 

Kevin, have you violated the first or second rule of post editing?

 

Rule #1:

ALWAYS, ALWAYS, ALWAYS, make a backup copy of your post before editing!

 

Rule #2:

NEVER, NEVER, NEVER violate Rule #1!

[cobra95kev]

I still have the original. I will try that tomorrow morning.

See...you're already smarter than more than a few 5-axis grammers!

 

Now, just make the same modifications one at a time until the anomoly appears, then you'll know for sure which change caused it.

 

It's a tedious process sometimes, but as long as you have your original copy that does work, you can tinker away until you get what you're looking for.

[cobra95kev]

I just tried with original post and still got the same output. It could be some of the mods I did to the machine definition. Which I still have that original too. It seems like I had to modify that because when I first started to use it I was getting an error of "Rotary Axis Limits Exceeded"

 

So I guess I will try the original everything and see what I get. I am just now trying cuting with the rotary axis moving so that is why I am just now running in to this.

 

Thanks guys.
