SOLVED: Fusion 360 Post Processing Failure - Tool Orientation

I am using Fusion 360 to generate tool paths and hopefully G-code to import directly into Easel for cutting on my new 1m X-Carve. Today I downloaded the Easel Post Process for Fusion 360 and pointed Fusion to that file for PP actions. For debugging purposes I’m trying to do a single simple 2D contour. Unfortunately, each time I try to post the G-code there is a failure. Here is a sample of the NC file output:


(STOCK/BLOCK,609.6,3.175,304.8,0, 0, 0)
!Error: Failed to post data. See log for details.

Trying to import this into Easel (even though it fails) gives no carving data. Anyone having similar issues or have a solution? THANKS!

A few questions:

  1. Are you running the Simulation process in Fusion? If so, what does the path look like?
  2. Have you looked at the log file in Fusion?

Looking at the gcode in your post, I suspect that there is no tool path in fusion for the post processor to process. Running Simulation will give you a popup error window in Fusion.

Never used Fusion 360 but if I remember correctly, I’ve read that the T1M6 line should be removed from the gcode before importing - either from the PP or from the resulting gcode.

You have to turn on the option in Fusion to open the generated code in the editor in order to see the log. Once you do that take a look at the log and post what’s there.

The simulation works and there is a proper tool path generated. No luck finding a log file yet.

Thanks StevePrior, do you know where that option is in Fusion? No luck finding it yet.

I don’t have Fusion in front of me, but when you actually do the post processing you bring up a dialog box, the option to open the generated gcode in the editor is a checkbox in that dialog.

I see that dialog but checking it doesn’t do anything. I’m starting to wonder if I have a bad install or something with permissions is blocking some functionality of Fusion. I’ve tried multiple other post processing files and all return the same error of inability to post.

If you go to the Post Process dialog and click on the “Open Config” button on the Post Configuration line, does an editor pop up (might need installing the first time)? I’m wondering if the editor that gets used when you select “Open NC file in editor” hasn’t been installed yet and maybe won’t be installed because of that checkbox, but will with the other Open Config button.

Some success but not out of the woods yet. I managed to get the NC log file to open in what appears to be the editor after telling it to post. Here is what is output. It appears that the major error is in tool orientation definition. I’ve assumed that setting up the work such that the Z-axis is the tool axis (up and down) is correct with the X-axis being left and right, and the Y-axis being front to back (relative to the machine). Here is the output as displayed in the Brackets editor.

I’d have to look more tonight, but it looks like it’s not the actual tool orientation that it’s complaining about, it’s that this post processor doesn’t support the specification of the tool orientation even being there. Did you change any settings regarding tool orientation, I don’t remember if there’s a checkbox related to that in the post processing dialog box.

BINGO! Thanks Steve for the interpretation of the error. I went back and reoriented the sketches to be on the front plane instead of the top plane (tool defaults to align with Z-axis which is perpendicular to the front plane in Fusion). I then turned off the redefining of the tool orientation and it posts now!


Good! You could have also changed the definition of the axis in the CAM setup instead of reorienting the model.

The intent of a “setup” in the CAM workspace of Fusion is to represent the placing of a piece of material in a machine in a certain way to perform operations on it. This is modeling real life, so you should have exactly the same number of setups defined as times you’d fasten the material in a machine:

  • putting the blank in the machine (that’s a setup)
  • taking the blank out and flipping it over (that’s a setup)
  • changing bits without moving the blank (that’s NOT a new setup)
  • moving the blank to a new machine (that’s a setup)
