I have been playing around with the Post for Fusion 360 and have it working OK.
Here it is for folks to try out. Be careful as not everything is tested. I mostly was working on getting the drill cycle to work properly as well as the C axis.
If anything doesn't work or errors out let me know.
The funny part is if I rename the post - it fails. I can't figure out that one.
I was struggle with a "no feed rate enable error" last night and finally got something going around 1am this morning. It was kicking my as on the drilling and tapping cycle but I finally got something going and was able to cut the first part. I'll try your post later to see how it does. Thanks
Sin - were u able to get a decent drilling cycle w a G94? My experience was that it would ignore the feedrate and rapid into the part so I changed the post to use G95.
Also if you issue a G291 it changes to iso mode then you can use standard fanuc code.
