Frage UCCNC and Fusion 360

Hi,

I don't suppose that anyone else has tried this combination?

The CAM module in Fusion 360 comes with a number of post processors for generating code. There isn't a specific one for UCCNC. The best luck I've had soo far is with the WinCNC post processor, which has worked well for peck drilling (won't do straight through drilling) and 2D contours with tabs soo far. I have to do each operation seperately to get the best, most consistent results.

The user manual for UCCNC suggests that the software can interpret RS-274 compliant code. There is an RS-274D post processor, so I would have thought that this would be the best post to use, however the code as interpreted by UCCNC does not detect arcs, so my nice radiused parts are shown as square edge parts. There is also a problem with the placement of some holes.

Rory, are you able to comment on UCCNCs exact use of RS-274? The post processor in Fusion is for RS-274D.

By the way, I would very much like UCCNC and Fusion 360 to be my standard toolchain. Fusion 360 represents fantastic value for money considering the cost of other autodesk products like inventor (not an autodesk employee!!)

Thanks,

Yes - try the Mach3 post processor?

Fusion is indeed excellent!

We will get more details on this when time permits.

I had tried the mach 3 post. I will try it again later today, in case changes I made to the operations afterwards made the model more optimised for the mach 3 post.

Autodesk forums seem very open to additions and changes to post processor sheets, so as soon as we understand what we need to give UCCNC we can submit to autodesk and get a specific post for UCCNC.

Mach3 post p from Vectric works with UCCNC directly. So if there is a Mach3 post - it should work.

Okeydokey,

I took some time to compare the paths produced by 3 likely post candidates. WinCNC, Mach3, RS-274D.

Here are a couple of images - they show the top-down and iso views of how UCCNC interprets the G-Code in each of the files. All files are produced by Fusion 360 Mac version 2.0.1457.

Top-down Image



Iso-View Image





WinCNC post produces an accurate representation of the part, and the RS-274D and Mach 3 Posts do not. There are differences in how the traverse paths have been calculated, as well as the shape of the parts - no arcs and they seems to truncate the widths of the parts.

I am using Fusion360 and mach3 post for mach3 and had no problem so far. It is generating also arc's.
Did you compare the g-code?

By the way, you can write your own post processor by changing another one (I did that when I still had WinCNC because I disliked some settings).

p.s.: The reason why I have choosen Mach3 and not UCCNC was that I could not test UCCNC in real life on maschine without buying license.

I downloaded Mach 3, and I see there is a plugin for the UC100. The program ran in demo mode just fine on my win7 64bit desktop. Will try it on the laptop tomorrow afternoon.

I can confirm that the Mach 3 post processor works with Mach 3 just fine (good news!)

There are differences in the G-codes produced by the Mach 3 and WinCNC posts. The following sections show the g-code for the same drilling operation for the Mach 3 version and the WinCNC version. I note that whilst the coordinates are the same between versions (true for both drilling operations for this component) the way the posts use G-codes etc isn't.

MACH 3
WinCNC
And UCCNC much prefers the WinCNC version.

Oh, Mach 3 is also quite happy running the RS-274D version, but not the WinCNC version because it uses square brackets and outputs G22 in my case which is not understood.

Looks like WinCNC post it is!

Hi Guys

I'm quite new with my SC600 V2 but not to cnc machining. I'm working with fusion 360 to do my first cut !

But I have always the same problem when I click on Cycle start in UCCNC : The current job workspace is out of the set software limits.
And if I look at the Iso view in UCCNC the volume/red line (not the cut itself) seems huge compare to what my stock/workpiece is on Fusion 360 (see img attached)...

I don't how to fix that ... I've already try a lot of settings in fusion 360.

Any suggestions are Welcome ! thx for your help.

Julien

Another screenshot with a different model. I've try few postpross (winpc, mach2/3 Etc...) . Nothing changed and can't find anything suspicious in the G-code file.

Can you send us the Gcode file ?

Done by Email Rory. Waiting for your returns . I will share the issue when everything will be fixed.

Thanks for your work Rory !

Hi,
I started using Fusion 360 CAM, to check how it works, but I always have erros (arc errors) when I load the file in UCCNC. With Cambam (my other CAM software) when I export to g-code (Match3 settings) to UCCNC works very well, but in fusion 360 when i export to g-code (match3 settings) I always get same errors, and in the preview screen of UCCNC doesn´t look very nice....
Anyone has achieve export to Fusion 360 to UCCNC without issues??

Thanks,

Hey guys,

I am having exactly the same problem trying to do a 3d profile around bored holes.

Has anyone had any success with Fusion mach3 and the UCCNC software?

We need to find a solution, because fusion cam is awesome !

Here is my request post on the Autocad CAM post request page.

Someone has posted a UCCNC post processor to try with fusion 360 to see if it works better.

here is the link to the file / post

camforum.autodesk.com/index.php?topic=8254.0

I´m going to test it.....

Thanks...

Ditto - this weekend some time. I had errors particularly doing large circular bores, or 3d sculpting....

Fixed,

The arc error, appears to come from the Tollerance set in the Pass settings menu.

It was set to 0.01mm, and I cahnged it to 0.02mm, and there are no more arc errors.

That was using the UCCNC software, but the M3 probably also works if you change the tollerance per pass to that setting

( the tollerance is not in the Post processor, but on one of the Tabs in fusion when you work left to right to setup the tool piece and orientation etc....

Also - tollerance is not available for some types of operations, as the menu changes depending on the operation type

Hi guys, very new to cnc and have not long owned my 420, apologies for dragging up a relatively old thread but I am having the exact same problem as this and was hoping if someone could shed some light on how to fix this or what I have done wrong.

Hi sc,

I fixed my issue by changing the UCCNC profile, it's nothing with Fusion 360 but how UCCNC read the file. To change it, go to configuration, profiles and should have a choice with different profiles (Stepcraft 2 420,600 or ALL)... If not contact Rory from Stoney CNC, he should be able to send it to you .

Also I use WinCNC post processor but Mach 3 should work as well.

Hope it will work for you !

Best,

Ju

Hey Ju, thank you for a super fast reply, unfortunately I already have the correct profile loaded so not sure what to do next.
