Post Processor for Fusion 360 to run Axiom AR8 Pro and other Axiom Models

Post Processor for Fusion 360 to run Axiom AR8 Pro and other Axiom Models

I have an Axiom AR8 and would like to use Fusion 360 since it is at the core of most Maker Labs across the country and allows seamless collaborative product development that the currently supported software from Axiom does not. I use it and teach it in conjunction with the Tormach 1100 at a local Maker Lab and it works flawlessly.

 

I might add kudos to the team at Tormach who took the bull by the horns and went very far to solve problems that they were having with various CAD software on Widows and were brilliant to take LinuxCNC and craft their own suprer-reliable clone called PathPilot. That is the kind of integrity that will drive the expanding educational and maker tsunami that our friends at Axiom have yet to commit to.

 

I would offer for anyone that has the time and requisite skill (i.e. programming, language interpolation algorithms, patches, and gcode knowledge) to generate sample gcode from Fusion and I will run tests, time allowing, on my AR8 machine to get a proper post processor in place as soon as possible.

 

Some suggestions would be to get a trial copy of one of the software products supported by Axiom (Vectric being the most popular) and create a simple test file - i.e. a simple block with 4 different radii on the corners and two pockets with climb and conventional directions, done is several depth steps and all with the same tool and then post the gcode for Axiom. Next export the vectors as DXF and import into Fusion create the same specifications of toolpaths and export the gcode for some generic default machine like MAch2/3 or GRBL and see what the differences are.

 

If you need any guidance from Axiom don't hold your breath. It seems they do not seem to want to get involved in anything related to software other than the products they sell and do not seem to have a grasp of basic GCode necessary to make any useful suggestions, most likely by design. Otherwise their product would run on an actual computer so we could see what file is actually being run before a random collisions or conflicts and other information that can best be seen and verified visually.

 

BTW - the guys at CNC Cookbooks have a GCode Editor and simulator that they are working on and they might be able to pitch in as well as they currently hold more experience with the entire knowledge chain of CNC from tools, materials, speeds and feeds to the actual gcode itself. So I'd hit them up for suggestions. They do not currently list the Axiom machines in their postprocessor list and might be excited to add them.

 

Anyway if I had more time I'd get involved myself but I have product to get out to global customers and shows to attend, etc. I will, however, as I mentioned, be glad to run test code and do "air cuts" before touching any material - time allowing - just to be able to provide a machine to whoever is interested. Please contact me on this forum if you are interested.

 

Let's get this done! Axiom machines are extremely well made, accurate and deserve a wider range of support than they are getting from those who should care.

Below are some links to my instagram as I don't have time right now to direct upload. I have created several models in fusion and cut them successfully using the Rs274 post.  As far as "checking" to see if they are accurate, I mold kydex plastic over top of them to form holsters/carriers for different items. The items all fit exactly as intended with no wiggle room therefore I am positive that nothing was lost along the way. 

 

I cut HDPE at .25" DOC, 165-180 IPM, 40% tool engagement. I have done so approximately 30 times since I purchased my machine. The results are shown below.   I believe it works.   Best of luck.

I tried with the RS274 this evening and the feedrate did not seem correct - it was SLOW! Am I missing a setting within AXIOM controller, maybe some kind of safety thing on?

@Anonymous  .... Yes, there is a setting on the controller to allow the program to set the feed rate instead of the controller itself.  Once you allow the program to control it, whatever you set it to it will do.

I have tried using RS274 post processor but all of the rounded corners in the model it didn’t round instead it made the corner into a chamfer 

I was just using a 2d contour to cut a shape out of a sheet of plexiglass

I'm not a start at this but...  Axiom A8 uses a Richauto A11 / A81 DSP controller.. That controller has already be post processor by Auotdesk in their ArtCAM program.  Wouldn't it be possible to draw from the ArtCAM post processor for Richauto to create a Fusion 360 Post processor.  I'm also looking into Axiom A8 for 4 axis projects and would love to use my Fusion 360 to CAM out parts.  Hope this helps.. Thanks.

From what I can tell, this issue has to do with the documentation provided by Hust. Axiom emailed me the documentation that Hust provided them for their controller. From what I can gather, Hust didn’t create (or if they did, didn’t provide it to Axiom). They just sent Axiom documentation for the H6D & H9D control panels that they make. While I’m assuming they all use the same GCode, it doesn’t make it easy to create a post for the DSP. It actually makes it a way bigger deal than it would be if they offered up the actual documentation for the controller that Axiom is using. I hope this helps add some light to why this has been taking so long. I’m going to try create one, but since I don’t have all the information I’m going to have to wait until I get a CNC from Axiom before I’ll be able to finish it (I was planning on writing it while I finished saving up for it). All I can add is that after seeing what they are dealing with, I totally understand why it’s taking this long and why no one wants to deal with it.

I don't know if I should make this a separate request or if this request should suffice, but I am looking at getting the Axiom i2R and it is controlled by a RichAuto B11 DSP. I'd hate to have to use the natively-supported Vectric V-Carve software (yuck) since I already have AutoCAD 2019 and Fusion360. A post-processor for this would be HUGE in my decision to actually get this machine.

I have the Axiom AR-8 pro with the rich auto a11 controller and have used the RS274 post processor. The only issue I’m seeing is on it translating the correct feed rates.

@AchimN has there been any progress in a proper post processor for the Axiom?

I have a AR16 Elite w/Hust Controller and am in desperate need of a post processor to utilize Fusion 360. I am fed up with the absolute foolish tool paths output by Vcarve Pro.

Need this as well, please make a post-processor for the Axiom Elite model!

Well, it seems no one is doing it.

I guess I'll do it.  I've got a used Chinese machine with a Richauto A18S controller. It also has a rotary A (4th) axis. 

I should have the post processor worked out by end of the month. I'll keep you posted.

Any update here? I've gotten RS274 to work, but the feedrates are way too slow. I've read other comments here but cannot find a way to have the machine read the feedrates from Fusion.

RS274 works fine. There is a setting on the controller to tell the machine to get federate from the program. If you do not change this setting it will run super slow and ignore anything you put into the CAM in fusion. Been using RS274 for years making 3D models that need to be perfectly accurate, it works.

On Axiom Controller do the following: 

Menu 

Auto Pro Setup 

GCode Setup 

 

You should see a setting F READ: 

If it says IGN F it is ignoring your feed rates. 

Change it to READ F 

 

This will allow you to change your feed rate in the program and it will stop ignoring it. 

 

Hope this helps, because Axiom could care less about putting out a post processor. They push VCarve which is garbage.

Hello,

 

The Richauto post processor which should run the Axiom machine can be downloaded here.

Thanks,
