Fusion 360 CAM changes due to recent changes by Autodesk to the "free" version. See this post for more info, or skip to here to install/reinstall the latest post processor And install the postprocessor from here: docs:software:fusion360 [OpenBuilds Documentation] (page also includes installation instructions) New post processor for the Duet here: Fusion 360/Duet post processor
Hello, I am attempting to use the openbuilds post processor for fusion 360 for my lead 1515 cnc. I have followed all the steps detailed here and have created valid tool paths within fusion 360. when I go to export my g code for said toolpaths it only exports as a txt file, which I can't use with open builds control. I have checked my nc extension and it is set to g code but I am still only able to get txt. this seems like I am doing something stupid but for the life of me I can't figure it out.
have you read the .txt file? .txt is usually an error message, tick the 'open gcode in editor' box on the post dialog so you can automatically check the output.
I have the open NC file box checked, It opens what appears to be the gcode just as a .txt file instead of a .gcode file.
What's in the "NC Extension" box above the post options? Assuming it's .gcode or .ngc, .txt is almost certainly an error message- I think Fusion calles it a FAILED file. It starts off with g-code, and then falls apart somewhere, you have to look at the end of the file, it shows what it was doing so you can diagnose how and why it failed. Edit: it actually is a ".failed". It'll be filename.gcodeExtension.failed, like this: Note how the ".ngc" (my gcode extension) is in the file name- it's not the extension. The extension is .failed, and hows up as a txt file with a Notepad icon. All of the successful posts show no extension because they're actually .NGCs and show up for me with a Notepad++ icon. Also note the file sizes- doesn't always fail after just the first few lines.
my "NC Extension" is set to .gcode. This is the ending few lines of my g-code. When I ran the simulation everything seemed to be fine.
Then just change the extension to .gcode and see if it runs? Nothing magical about a g-code file, just a text file with an alternate extension, like an HTML file or a bunch of other files. Now WHY it's doing this... Not sure. Makes no sense.
I think that as with your windows setup Rob, his is hiding the extension but the file is actually named something like myproject.txt.gcode windows strips the .gcode for display, making him think it is a .txt file. some viruses rely on this to hide themselves. I recommend turning off the 'hide extensions' (rather dubious) feature (-: In any Win10 file explorer click 'view' then 'options' on the right, select 'folder and search options' then 'view' tab and make it look like this, then hit the 'apply to folders' button
I used to do that, I didn't like it when they took extensions out of view. Now I'm fairly used to it since I've used so many computers in different places... BUT: this is why, in any document folder, I ALWAYS run it as a View->Details pane. Date modified, Type and Size are critical for knowing what you're clicking on. Filenames can be deceptive, but the document data doesn't lie (...usually).
Anyone know the solution to the latest changes to Fusion 360? I can't seem to enable cloud config on my system. Is there a new procedure? Thanks.
I can get to Home -> Assets -> CAMPosts no problem. I can also access cloud posts from the Post Process window. What flavor are you running?
Dropped a new post version last night, v1.0.37 This includes a tape splitting feature that allows you to set a line limit, gcode files will be output until the line count limit is reached and then a new file is started. This allows you to split a multihour finishing pass into shorter files. (though it will work fine for multiple operatiopns and multiple tools, it is recommended that you use it on single operations that run for long periods). How to know how long to make the limit? If you output an operation that will take 4 hours to cut and the gcode file has 250000 lines in it, but you want to cut in 1 hour segments, then simply set the line limit to 250000 / 4 = 62500 but you do want to round up a little else you will get 5 files with the last one being very short, so maybe use 62750 as the limit and check how many files you get. WARNING: failure to run the files in the correct order, will cause a crash. failure to Home the machine consistantly will cause a crash. docs:software:fusion360 [OpenBuilds Documentation] (the x32 post does not include this functionality at this time)
yes. end of file 1 will retract beginning of file 2 will position to same place, plunge to Z depth at plunge rate and continue. late last night had the thought to instead of hard spliting when linecount it reached, to flag for split and then split at the next rapid move. This may be better on finishing passes where the plunge to cut depth may well leave a blemish, but it does mean that there may be a coupla thousand extra lines before the next rapid motion, so file lengths cannot be guarranteed.
Thank you very much for this David. I've posted the link to your post (and to Openbuilds Control) in my Facebook group and I'll message you with any feedback. I hope to have a go at porting your code into my post processor for the Duet over the weekend. Alex.
This is a great idea, and prodded me to think of a simple way to do it with Vcarve. To mimic this, just split the model into smaller pieces with vector boxes and choose the contents of the vectors as model boundaries. A slight overlap would be beneficial. Save as separate tool paths. Others may have already thought of this, but I hadn't until I read this Fusion post.
Much easier in Vectric - see pic. You have to change the number of lines/file by editing the post processor though. Alex.
