CAM setup shows no errors, Post-processor does

[BrianOfShope]

I have a file set up and tool pathed for an older, probably CNT Motion 950 router. The operations all simulate without any errors, but the WinCNC processor flags for errors. Specifically, it posts errors on a series of holes that I've tried several different solutions between operations and tools, but nothing works. The operations I've tried are Circular and Contour, with .125 and .25 bits. On of the holes is a essentially a counter bore, but with a very narrow bore.

As a beginner at this, I'd guess that I have lead in/out issues, or need to address a different option in the operation that this unique cut requires. I'd be grateful for any ideas or directions. I can also post pics of my setup, if that would help.

Hi @BrianOfShope,

Pictures and. Specific error message will help us solving you your problem. 

Can you share your model so we can take a look at it? Also tell us witch Post Processor you are using. 

If my post answers your question Please use  .Accept as Solution & Kudos This helps everyone find answers more quickly!

@Marco.Takx Thanks so much for responding. I've posted the pics of the offending operation, as well as the G Code file. I'm not in front of the machine, but I'm pretty sure it kicked the error out at line 192. I also have had an issue with the post conflating M3 command on the same line of the spindle speed, and that produced an error. Once i fixed that, it generated this one. Perhaps the G2 command needs it's own line...?

A a screen grab of the offensive line of code. I tried uploading the .tap file, but it won't work for some reason.. The model itself is here.

The file you linked to us is not able to be downloaded, just viewed. Sadly, this does not give us enough info to guide you further

Please export and share your .f3d file so we can provide better assistance. To do that:

File > Export > Save to local folder. Return to thread and attach the .f3d file in your reply.

If the file contains linked component, the links must be broken. If the file cannot be shared due to privacy concerns, you can email me the file: seth dot madore at autodesk dot com

Sorry about that @seth.madore. The file is attached...

Do you know that the WinCNC post processor is the one to be using, or is that just the one you've tried.

Are you certain that it's alarmed out on that line specifically? And by alarms out, are we talking "it stops hard and will not proceed"?

[BrianOfShope]

Re: Post, kinda both. The router is a CNT Motion machine, and when I called they said that this was the post to use. I'm trying to get my hands on one that was modified particularly to this machine, but haven't had any luck yet.

As for the code, I'm somewhat confident that this is the line that alarms out. If I understand your definition of that, it returns a hard error in red with a report on the line of code. It will will not let me cut the file. As I've tried different operations and modified the toolpath, it always has returned the error in a line similar to 192. It has the G2 command and I code in the line.

Thanks for your help, Seth. I'm grateful for the assistance!

Do you have any programs that have been run on the machine with another CAM program? I'm wondering if your machine supports I/J arcs. Unfortunately, the WinCNC post does not have the option of switching to "R" values, but there are other posts that do. I'd like to see some proven code (run with success) before I recommend an option

@seth.madore Sorry I've let this post languish; it's taken me a minute to get back on the machine to check the post. After using a different config for the same machine, I was able to get it to work without any alarms. 

Thanks again!

Thanks for circling back, but I am still curious what post you ended up using. It's good info to have should someone else stumble upon this thread and have similar issues

Indeed. I'm cutting on an older CNT Motion 3 axis machine, I believe it's the 950 series circa 2003/04. Their support staff, which is one of the guys who actually builds and installs the machines, directed me to WinCNC. My understanding is that its a generic post platform, and you config your individual machine to it's nuanced macros and commands. I ended up using a config from a different CNT Motion machine to work, since it's also using the WinCNC post.

I hope this is helpful for folks!
