On OSX the folder is: /Users//Autodesk/Fusion 360 CAM/Posts/ on windows the location is shown at the top of the ‘Post Process’ screen as below. Simply copy this file to the folder that houses the post processors. Solution 1 (preferred): A simple fix is to download this post-processor, that we have edited, and install it in Fusion to be used instead of the default. We have no idea how its actual functionality could be considered useful or why it is turned on by default. Why after moving over right next to your stock and setting your Z Zero point would you want to run off back to home only to turn around and come back at the start and end of every job?.Often the origin/home position is actually right at the point where a homing / limit switch will be pressed and that means that you will get an error and have to rehome your machine.So G28 is a goto home/origin position which is being placed near the start of your g-code file (and at the end) and there are two problems with this: ‘G28 Start Job VIA Home’ would be a better description. G28 Safe retracts sounds like it will retract the Z before doing anything and anything ‘safe’ sounds like a good option to turn on right? While it sounds nice and handy, it does nothing like its description. This is a default option called G28 Safe Safe Retracts. ISSUE: The machine tries to run off to home at the start of a job and this just hits a limit switch. You may experience issue A by default, and then when in an attempt to remedy this situation by simply turning off G28 Retracts you often end up with Issue B (whether you have noticed it yet or not)

These are likey both parts of the same issue. or B) the machine drags your endmill across the job (very quickly) destroying the endmill or the material before the job has begun.A) machine runs off to home before starting (and at the end of a job) tripping a limit switch in the process,.The default GRBL post-processor in Fusion 360 can sometimes cause a few issues when initially getting machines up and running.
