So I'm a new owner of a Pro 8 and am still trying to sort the bugs out as far as posting to the controller from Fusion 360. I really don't want to have to get $700 worth of VCarve software just because it's been "tested" more with Axiom.
I've been using the post processor that folks on this board as well as the Fusion board list for the Axiom controller but I'm still having "random" stall issues. Last night was almost 1 hour into a detailed 3 axis vacuum forming mold when it stalled in the Y axis (while doing a move to another spot) throwing everything off by 1/4"..... Needless to say that was a trashed part.
Brand new machine, super clean so it should not be a binding issue.....
Thoughts from those using F360?
Later,
Awall

That kind of sounds like an issue I had a couple of months after getting mine. I was using an 1/8" ball nose to finish machine a 3d carving, using an offset toolpath, which, for my model, went in a circle. About 2/3 of the way through, the Y axis would make a weird noise, and get thrown off anywhere from 1/8" to 1/4". Chad at Axiom suggested my feedrate may be too high, so I went into my tool database in Vectric and lowered the maximum feedrate, and the problem went away. He said that making a circle is one of the hardest things on a cnc because of the sudden change in direction every 90 degrees. I'm not familiar with fusion 360, but surely there is a place where you can lower the maximum feed rate and give it a try. Good luck.

Awall...
There have been numerous posts around the net about bad code out of Fusion 360, especially for our smaller machines. You may want to try one of the following:
See if a user with another machine can run your code
See if another user with a Vectric product can post out your file for you. I can understand not wanting to pony up the $ for VCPro, but in the long run may turn out to be less costly, especially in the frustration department, than some other products that "seem" to be free.
Remember... if it seems to good to be true... you know the rest

Autodesk says Axiom should do it. meanwhile, users are left out in the cold. i know of two Axiom machines that haven't been bought because of exactly the above attitude.. and i imagine there are more. I'd personally order an Elite, tomorrow, if one of these two companies would step up and provide proper support. |

I'd personally order an Elite, tomorrow, if one of these two companies would step up and provide proper support. Same here - I'm a paying customer of Fusion 360 - I was one of the early adopters of the software. I use it everyday with my Tormach machines and anytime there is a post issue "both" sides jump in to fix the bug. Prior to purchasing - I was told by the manufacturer that I would have no issues using Fusion 360 to post files to the machine. This has just not been the case. I'm still chasing stalling issues, having to covert the file to metric prior to posting and other little issues. I wish that Axiom would realize that MANY folks have transitioned over to F360 from programs like Solid Works. Yes, I'll agree that F360 had some challenges in the first year or so but for 90% of the users out there, you cannot beat $300 a year for a full package CAD/CAM solution. So, as a new owner, I'm pleading with Axiom to help us out. I just wish I knew more about editing the post processor. Later, Awall |

Sadly, post processors are not developed by the machine companies. We do not have the understanding of the software that those companies do.
This is the same for all other software developers, VCarve, ArtCAM, BobCAD, Rhino and even the larger companies like MasterCam. They are the ones that support the software. Each of them creating posts as needed for customers.
They also do not charge for this service.
To date Autodesk has first recommended a generic post which did not work for many customers, so we could not recommend the software.
When it became apparent that many problems with the GCode running on the machines was possible due to customer settings on the CAM side of the software, we became more open to recommending the software for user who do not want to purchase VCarve or another software.
For much of the year the handful of customers that were using Fusion were reporting great results. In fact our own design team in Taiwan is using Fusion with the Mach3 Post and is successfully creating a large number of designs.
With the small number of Fusion users though, the software is not really tested for every function with our machines. And issues appear occasionally.
They have recently created an Axiom Post, but we can not say whether or not this is a new post or just the old generic RS274 post that has been relabeled.
Customers have requested that we provide the G & M code lists to be used for post development and we have, unfortunately the post created has not shown itself to work as intended.

There is always an issue with various machines supporting different G-code dialects, thus the reason for so many post processor files. You or Axiom could modify one that is close, looking through the supported commands and changing what is appropriate. Regardless of what CAD/CAM software you use, it's always a good idea to check your output with a different piece of software because most CAM renders are not done based upon the G-code generated but the original solid information. I use a free tool which is actively updated: www.nc-corrector.inf.ua/index_EN.htmBut this one has several advantages and if you pay for one-year subscription it will still work after that expires but with reduced features: www.cnccookbook.com/CCGWizardE.html |
