Setting up ShopSabre 23 with Fusion 360

I’m trying to configure Fusion 360 CAM for use with a ShopSabre 23 machine.
I think I’m setting it up correctly in terms of size, but it would be nice to hear what other teams have theirs set up with. Like is the X good with travel from -3" to 31" ?

I’m also not sure what the set up for the kinematics should be, one video I watched switched the location of the “head” and “table”, but that was an older version of Fusion 360 and there are fewer tabs for setting up in the machine definitions.

I think I’ve got the post processing set up with WinCNC for ShopSabre, but someone correct me if that’s wrong.

Is there a way for someone to just export their set up and I could import that? Searching online has yielded me nothing.

I’ve been trying to learn as much as I can about using a CNC, but it feels like all the resources are for machinists, so as beginner friendly as can be is much appreciated.

We have the IS 408 model but just use Vcarve software that came with the machine PC. We have found it very simple and effective to learn and use. We also have some Haas CNC machines in our shop that we use HSM works with but stick with Vcarve for the simplicity with WinCNC/ShopSabre.


You can get Mastercam for free through the KoP, and they can give you all of this as well for a Shop Sabre!

I don’t have a ShopSabre. I have a Camaster Stinger, which is controlled by WinCNC, so the mileage on these comments may vary. I don’t have a machine file to post for you to import.

I’m not sure how much the axis size settings matter in the Fusion 360 machine setup. From what I can tell, they are mostly (exclusively?) used for machine simulation in Fusion 360. If I put a sheet of material on my router and set the X and Y zeros in WinCNC somewhere in the middle of the sheet for where I want to start cutting, Fusion 360 knows nothing of that. If Fusion 360 had axis limits of my table size, those would not apply if my operating zero was not at the table origin. If I’m cutting tube in a jig, and my WinCNC Z zero is at the top of the tube, any Fusion 360 Z limits for the machine would no longer apply. I’d be limited to a Z travel of maybe 2" for that cut vs the full Z travel capability of the machine of say 6".

My suggestion is that you get your rapid and feed max rates set to the specs on your router and put in your machine travel dimensions for the axis limits. Create your toolpaths and if the toolpath simulation in Fusion 360 looks good and the toolpath preview in WinCNC looks good, you are probably going to be good to go. It’s going to be up to you to create toolpaths that stay on the table and are within the height limitations of your spindle. WinCNC should alert you if your toolpath is going to violate physical limits of your machine given the current temporary zeros you have in place on all the axes.


I’d recommend checking out the System Configuration section of the WinCNC user manual, then opening the WinCNC.ini file (in same folder as the WinCNC.exe). ShopSabre should have setup that file with the appropriate limits, axis speeds, etc. specifically for your machine, so you should be able to work backwards from the values in that file.

I know you asked for help using Fusion 360, and if you’re committed to going that route then ignore the rest of my post

If you’re new to CNC machining, then I would recommend using VCarve Pro rather than Fusion 360 to start out. ShopSabre’s YouTube channel has a huge playlist of how-tos and tutorials on running your machine using the “VCarve → WinCNC → Running the machine” workflow. Nothing against Fusion 360, but the amount of support and training material available specifically for your machine with VCarve is invaluable when starting out.

We have a 15 y/o ShopSabre that we were able to bring to back to life this year with a single phone call to ShopSabre support and then learning from their YouTube channel

As a converted Cut2D user, once you’ve got templates set up in Fusion 360 it’s hard to imagine going back to a Vectric product for FRC-type cutting needs.

Not as familiar with Fusion360 CAM but I’m going to assume it is pretty similar to Inventor HSM. There may be many options to define information about the machine, but they shouldn’t be nessisary for your application. Defining things about the table for example might be needed for a complicated 5 axis operation, but shouldn’t be needed for a router. You just have to make sure yourself that the part you are trying to cut fits in the preview. Worst case scenario you hit a limit switch. Unlike a typical 3D printer, you will often move the origin (not in CAM but at the router itself) on your machine to define where your g-code will start, rather than always using an absolute origin.

My senior year I was tasked with learning how to use our new ShopSabre RC4 and it was rough. It’s a steep learning curve at first, but once you make your first few parts, it’s smooth sailing from there.

We have a Shop Sabre Pro 408 We have been using inventor with HSM

I have been looking at using Fusion360. These are some resources I have been looking at.
