Looking for an updated/better post processor for AXYZ Pacer 4010 ATC

I recently upgraded to an AXYZ machine from an older CNC Router Parts machine running Mach.  I have noticed an issue with the AXYZ machine starting and stopping on a arcs or slowing down in a tight radius, even with out any feed optimization turned on.  I tried looking at the .nc file in NCViewer and it is all over the place. (I added screen shots of both)  I contacted AXYZ and they suggested I switch to V Carve, that the post processor in Fusion 360 may be adding too many nodes.  I have been using Fusion for my post processing for the past 4 years and really do not want to have to switch if possible.   

 

I am hoping that someone out there has had a similar problem and can offer some help or knows of someone I can contact about an updated post processor.

 

Machine specs:

AXYZ Pacer 4010 ATC 

10hp HSD Router

Tangential Knife (if that matters)

Hello @kylesuon4 

 

In order to be able to diagnose, can you give more information please?

You provided 2 pictures :

Screenshot 2021-06-17 113830.png   is this the output from your previous machine ?

Screenshot 2021-06-17 114034.png   is this the output from your new machine ?

 

Apparently, the axyz can support plane selection via G17, G18, G19, but it doesn't seems activated in the post.

Another issue can be how the I,J,K variables are interpreted (absolute, or incremental from the starting point)

 

Do you use the post from the online library?

Can you share your Fusion file, and the post you are using?

 

If you have a programming manual for the machine, can you check how IJK are defined.

Because we only have a list of G and M codes supported, but no additional explanation.

 

Have a nice day.

 

Regards

Thank you for your response.  I changed the name of the screen shots to reflect which post was used.

 

I am using the post in the Fusion library, I have attached a copy, along with a sample file.  I am not able to share the actual file I am working with on my machine but this file has all the same shapes and movements.  

 

I also have attached a list of G and M codes which shows how I,J,and K are defined.

Hello @kylesuon4 

 

There is some issues related to the post processor, other from NCViewer.

 

Firstly, the version of the post was only supporting arc in the XY plane.

As the machine seems to be supporting G17, G18, G19, i have added support for the arcs in the regular planes.

I also forced the output of IJ, IK, JK depending on the situation.

 

Be carefull when using NCViewer, it's not always accurate, depending on the machine the IJK values can be absolute from the origin of the part, or incremental from the start of the arc.

(Fanuc is for example incremental from the start, heidenhain is absolute, Siemens depend on I=IC(), or I=AC() )

I am not sure that NC viewer handle all situation correctly as there is no settings in the software, and the nc ouput doesn't use any different code in this situation.

I have attached the modified post.

As we are not sure about absolute / incremental, try the program, using reduced feed rate, plus if possible, an offset along Z.

 

If it's working ok, please give us feedback in order to fix the online post.

 

Have a pleasant day.

 

Regards.

 

PS the post is zipped or else the forum doesn't accept the attachment.

@serge.quiblier 

I finally got some time to test this new post.  It seems to work much better.  It is still giving a slight pause on the inner arc but it is no longer stopping.   I was wondering if there is any more fine tuning that could be done to eliminate the pause all together?  Please let me know what info you need from me and I will do my best to get back to you in a more timely manner.  

 

Thank you again for your help.

Hello

There is no easy answer for this last behavior.
On some controllers there is sometime a code as G9, G61, G64 for changing the speed control on the machines.
On the high-end controllers for multi axis machines we can also have smoothing, or high speed functions.

After looking at the M/G-code reference available, I don't see any code corresponding to this kind of functionality.

It can also be related to parameters settings on the controller.

As this is totally controller specific, I don't know the AXYZ enough to guide you for solving this.

Regards

I am also experiencing this problem. If the modified post eliminates these issues on my AXYZ machine, can the AXYZ post processor in the fusion cloud library be updated?

Hello @djh5309 

 

you can start by downloading and testing the archived post attached to the message #4.

If it solve your issue also, just give us feedback.

Modifying the post will take alittle time, between the modification, the testing, the approval, and updating ot the repositories....

 

Regards.

I too have an AXYZ router and have had this issue as well as helix related issues. I get nc errors or just the machine stopping after dropping to Z0 when the helix angle is too low. In many instances I have to increase the angle to the extremes and lower my feedrate into a zone where tool failure is likely just to get it to perform a boring operation. The modified post processor didn't resolve my issues.

Has there been any progress on this?

I'm using an AXYZ Millennium and use Fusion 360 exclusively for Cad/Cam. 

I am about to do some testing of the current available post in 360 but if I should be doing something different please let me know.

Thanks

Ken.

I've attached the post that I have been successfully using. It was provided to me my AXYZ as being the post they use internally for Fusion.

 

Let us know how it works out for you!
