Fusion 360 mill/turn and turn post processor non-existent! (use Intercon)

[francoCNC]

You guys are awesome! I think you may have found a bug that lives in all Fusion 360 turning posts. I've started a thread on the Fusion360 forum. I'm sure they will figure something out in short order.

So I finally got around to trying to make a part using Franco’s turning post processor. It seemed to work fine except for one thing. When parting off, the tool went way past the center of the part and seemed like it just wanted to keep going. Stopped the program to avoid a crash.

The Fusion simulation didn’t show this so I thought maybe I didn’t have the tool offset set up correctly. So I tried to make the same part but using Intercon and it worked fine without changing the tool offset. So, I assume the tool offset is okay and there’s something weird in the post processor.

Gcode is kind of a mystery to me but I noticed for the tool change it is “T0600” rather than “T0606”. It’s like this for all 3 tools I’m using for this part. It seems this works for the other tools but not tool 6.

Figured out why the offsets weren't in the code...I'm using generic tools that I found in the Fusion tool library and the offsets weren't enabled. Not sure why the first 2 tools worked fine but not the last. Probably because the first 2 tools are very close in length.

That will do it for sure. Good thing you noticed it rather than have it just barrel through a part.

Looks like another tweak is needed at the beginning of the turn post in order to use "milling" features on the lathe. It may seem odd to want to use milling features on a lathe without live tooling, however Fusion360 treats a drilling operation as a milling feature, so there is no real capability to drill or use an endmill as a drill and then an internal boring tool as I am doing, without enabling milling capability as well.
