I'm getting started in Fusion 360 and looking for a post processor for a Next Wave Automation Piranha CNC router. I found another post without a reply in another Autodesk forum, here. I contacted the manufacturer and they said talk to the software publisher. I can provide g-code from the mostly 2D software (V-carve) the machine came with.
Attached is a simple tested toolpath of a semi-cylindrical cutout that was created with Fusion 360 then exported as STL and imported into V-carve. V-carve can produce 2.5D and 3D toolpaths but lacks many options pertaining to 3D. This machine has no tool changer or travel limit/home switches. Neither coolant/chip removal nor spindle on/off/speed is controlled by the machine. I have no idea on the helical interpolation; I might be able to find that out from NWA though.
PS: The toolpath produced has a .tap extension but I had to add txt so the forum post attachment function would work.
Well actually, if you could program and post out a square with corner radii as well as a circle in the middle, that would be great. Something like this:
2" square (any thickness) or metric 50mm
.25" or 6mm corner radii
.750" or 19mm bore in center of part.
Reason I'm asking this is so I can make sure it supports certain g codes as well as how it handles arcs. Your prior attached program is nothing but G01 moves, so I need to check something

I think I've got your post tweaked to a point where it should work just fine. Let me know if you have any issues.
In your samples, you had a lot of comments regarding the stock setup and job descriptions, basically a mini setup sheet. This post will not be doing that. I'm not sure if it is possible even, to the point that the V-Carve was outputting. Someone smarter than I would need to comment on that

Ok, I tried to generate a toolpath using this post and got a 'tool orientation is not supported' error; log file is attached. I set the origin to the same as I use with V-carve; attached is a screenshot of the cam screen with toolpath.
I thought it might be something like that but I couldn't get it to generate a toolpath with other orientations. Like I said I'm fairly new to Fusion 360 so probably a rookie mistake. Here you go!
When you start a setup, you need to select the orientation of the part. Sometimes you get lucky and parts are already Z axis pointing up, but not often. So, from the drop down, select "Select Z axis and X axis Orientation" Once you do that, you can than get rid of the Tool Orientation you had selected.
The purpose of the Tool Orientation option is for rotary 4th axis work as well as 3+2 indexing

I got a 'opening local files is not supported' when I tried to open the attachment but I corrected the origin on the setup on my original and it generated a toolpath that was successfully tested.
I have a simple project with 2D contours and I've run into a problem. The first contour runs fine but the second is skewed and off size; 13 lines of the g-code are ignored. Attached is the project file and the two toolpaths. The 'Rabbit.tap' is the toolpath that has the problem. Also attached is a photo of the result. Any ideas?
I don't see any way to tell which lines are being ignored on the controller but I'll try to make a similar toolpath using V-Carve if that helps; see attached.
