If I orient the file correct to my machine and try to make a rotary on Y toolpath, Artcam gives me an error regarding the toolpath unwrapping on the wrong axis. Either way I can't win to make this cut properly.
When I type in 360 in the X axis on Ncstudio, the rotary turns 360 degrees. So I know that my motor parameters are correct.
Any help is greatly appreciated.
Thank you
What version and build of ArtCAM are you working in? To confirm this, select the Help > About ArtCAM menu option in your ArtCAM software. For example, ArtCAM Express 2015 R2.SP3 (64-bit build 860).
When saving your toolpaths from your ArtCAM software, what post-processor are you selecting from the Save Toolpaths dialog's Machine file format list box? Please check and confirm.
I have tried quite a few post processors but mainly Model Master 3 axis rotary X-A, and MMflat, I was told these were the one's to use for my machine. But then again the support people for my CNC have been less than helpful. They even told me the wrong motor parameters, I had to discover that one for myself.
If you've only recently bought your CNC machine, I'm surprised that your supplier has provided you with ArtCAM JewelSmith 2012. I would expect an ArtCAM sales partner or reseller to have shipped ArtCAM JewelSmith 2015 R2, as ArtCAM JewelSmith 2012 was discontinued years ago and is no longer supported. If you provide me with your dongle number, I can try to determine if you're licensed to use a more recent version of ArtCAM JewelSmith. Alternatively, you might want to enquire with your supplier as to why this has happened.
Actually our company has been using Artcam for the last 8 years or so, our last update was to 2012. We also use Gemvision Matrix so we haven't found a need to upgrade to the 2015 version just yet. But the Chinese CNC is new to us and we are trying to use Artcam to create and make toolpaths for it.
OK So I tried your recommendation and the toolpath shows up fine, but it does the exact same thing that the old flat toolpaths did. It was oriented fine but the rotation was only less than 45 degrees. The rotary did not turn 360 degrees so I only saw a section of the piece getting cut.
Here is a simple part I am trying to cut, including the toolpath I made with your recommendations.
Any thoughts on what I am doing wrong? Also I have the Y axis set to degree increments. I have tried the mm radius as well and get the exact same result... same with turning off the Y axis rotation button as well...all the dry runs have been the same.
This particular issue has more to do with your CNC machine and NCStudio than it does with ArtCAM JewelSmith. It really is the responsibility of your CNC machine supplier to advise you on what NCStudio settings are required, and to supply you with a compatible configuration file (*.con) for ArtCAM software.
Looking at the toolpath, the x rotation goes from -23.5619 degrees to +23.569 degrees, I'm not sure why but it looks like it's only moving about 45 degrees back and forth on each advance of the Y. So I'm guessing it's the postprocessor. Do you think I'll need Artcam to make a custom one for me?
There is no model number as it was special made to size and not a standard unit. It came from Lintianzhiyuan,ShanDong Numerical Control Machine Co.,LTD. The Driver and Motor are 86BYG-450A stepper motors and Leadshine drivers (M542).
Using the dongle number you've supplied, your company is entitled to use ArtCAM JewelSmith 2012.SP2 (build 359). Therefore, you're already using the latest version and build of ArtCAM JewelSmith available to you.
If you encounter an incorrect axis during rotary machining, it is likely that that you will require a post-processor modification. If you are interested in arranging for a custom post-processor to be developed on your behalf, then I recommend that you contact Scott Ingram on 1-877-335-2261.
That said, I would've expected your CNC machine supplier to have confirmed the name of the post-processor compatible with your machine. If the post-processor is not included as part of the ArtCAM software installation, they should send you the Post-Processor Configuration file (*.con) so that you can copy it to C:\Program Files\ArtCAM 2012\postp on your computer and then choose it when saving your toolpaths.
As I said before, we have been using Artcam for quite a few years now, but for a ModelMaster. We just bought this new machine by itself and it did not come with software other than Ncstudio. They said that we could use the ModelMaster post-processor so they did not give us any other.
I had tried the MM 4 axis X-A for rotary until I realized that the machine uses the X as the A and is not a true 4 axis machine, but uses the X axis as the rotary. Knowing that, I tried to use the ModelMaster Flat which I thought should wrap around and I wouldn't have to swap the X and Y as it does in the 4 axis post processor.
All that said, when I try the flat, the rotation is only about 45 degrees or so, not the full 360. So is that a post processor problem or should I change a setting in Artcam to create the proper toolpath for my needs using the ModelMaster Flat PP? If it's the PP then I will give Scott a call.
Sorry for the long winded reply, I just need to know if the flat SHOULD be working as a rotary but isn't. (as in this video: Artcam flat - rotary cut)
Thanks again!

It's stupid really. The axis is set up on Ncstudio at 360 which I automatically assumed was in degrees. I mean why wouldn't it be? It's actually set up as 1 degree is equal to 1 mm in the model. So I have to import my rotary model into artcam (I use Matrix mostly sorry), unwrap the model in the desired position, then I need to alter the file size asymmetrically so that the X axis is always 360mm no matter what the actual size of the piece is.
I end up with a very fat rotary but it seems to be working. If you know of an easier way or if you think they can write a custom toolpath that will change the calculations for me, please let me know and I may ask to have it made.
Thanks again for all of your help. I hope this helps anyone else with this problem. It's a crazy fix and I hope maybe you'll have an easier way to do it. But even if not, it's working properly now. I may just change the hardware and go Mach3 down the road.
Cheers,
Well this is what has worked for me so far. It's a huge pain but it works. In the near future I will install a new 4th axis controller and card and use Mach 3 instead of NCStudio.
1: Import your stl file in Artcam
Whole or select vectors (if you made vectors to mill around from your model), select raster, select your bit, define your material (make it the same height as your model). Name it and hit calculate now.
8: When milling make sure you are centred and have turned off your X axis and plugged in your rotary axis. Also make sure that you have changed the X travel in NCStudio to the correct motor specifications of the rotary and not the table.
Thank you for your reply, I just fixed the problem just few days ago, but don't know if it will work for you and i don't think you need to buy anything extra. Do your drawing normally, go to your tool path, select you tools and what ever you need to do, but before you press now just go to Model just after edit tab on top, clicked on Set Size Asymmetric... a box will appear, no matter what dimension is in the width section, just change it to 360, it will change your 3D view image, but does not affect your original dimension to your drawing. After this check your Set Position in the same model tab make sure it is the position you want, now you can press NOW! everything should be fine. Do let me know if it works for you?
Yes that seems to be just what I do as well. Accept I change the thickness of the model after changing the width to 360 because it seems to adjust the height so shrinking the relief to the original size will fix that too. You said you are re-adjusting the location so that is probably the same thing, it will change the diameter based on this.
Still it's an inconvenience to have to do this to every model. I was hoping a custom post processor would do all of this for our machines but I may just go the Mach 3 route. I think the machines perform better in mach 3 from what I've seen as well.
Best of luck and thanks for the input!!
Another way to solve this issue is to buy ucancam software, this is commonly use in China and I was told it will work perfectly with my cnc. You can do all your design in artcam and save your file has stl. or obj. and import it to ucancam, I will be buying it next month, will let you know how it goes.
That's great to know, please let me know how Ucancam works with your router, especially on the rotary (once you get it). I'd love to know if there is something out there that will save me the cost and effort of changing the whole thing to another system.
