Post Processor

Post by Tscholl »

I am running a Biesse Skill. When I save and run a file it cuts flipped in the x axis. I can flip the file before I save it and the file runs correctly.
Any suggestions?

Dear Tscholl

I see your no-one has posted any suggestions. Perhaps ask Vectric directly - Email at: support@vectric.com

I watch with interest

Sincerely and in good faith

Contact Biesse.

When a machine does that, it is indicative that someone designed the machine with the zero home switch on the wrong end of the axis.

Not as uncommon as one might think. I worked for a very large, very prominent Japanese manufacturer, sure enough, they introduced a model that had the exact same problem as you are having. I created a special post for it that fixed things.

If you do attempt to modify the post, keep in mind that you not only have to change the sign of all the moves on the offending axis, you also have to shift them by a set amount. Essentially what you are doing is mirroring, then moving the parts so they reference the opposite end of the machine. At least that is what I recall having to do. When you mirror them in Aspire, that takes care of the sign problem AND the shift.

You'd usually change the post from this:

VAR X_POSITION = [X|C|X|1.4]

to this:

VAR X_POSITION = [X|C|X|1.4|-1]

To flip the axis. Note that this may require changing the origin in the job setup.

For example, on our Morbidelli, Y 0 is in the back, and Y 49 is the front. I setup the job to go from Y0 to Y-49, and invert the Y in the post.

Or, in typical Italian fashion, they have a backwards coordinate system. :shock:

Thanks All
I did email support@vectric.com - I have not received a response. I have contacted Biesse they say it is an Aspire issue. Aspire has said it is a Biesse issue.
ger21 how do I go about changing to post?

Confussed?

Dear Tscholl

Wow.. You are really up against it here.

I am a little confused.. "I did email support@vectric.com - I have not received a response and Aspire has said it is a Biesse issue."?

Still watching with interest

Under the Help menu in Aspire, there's a post processor editing guide.

Vectric is pretty good about responding. Check your spam or junk mail folder in case it got put there. Also, ensure you are using the same email address that you used when you registered the software.

This what I received from Vectric concerning the Biesse Skill post processor. any suggestions or thoughts?
Thanks

Hello Todd,
Many thanks for your inquiry.
I am afraid that we cannot currently support later model Biesse machine tools.
It is our understanding that the older "ISO" and "DAT" formats are officially deprecated on the later models.
Our understanding is that the "CIX" format is now the recommended format.
Unfortunately developing code and fully supporting this format is a major undertaking
and as we currently have no way of testing the code ourselves,
introducing post processors for this format will be a lengthy process.
One of my colleagues is currently looking into support for the CIX format,
but I would imagine that it will be in the region of 6 -12 months before we would be in a
position to start offering post processors for the newer models.
I hope that this helps.
Regards,
Mark.
