I use Fusion, which always adds Gcode at the end of the final operation that sends the Holder to the Home position. I want to eliminate that return to home code. Instead, I want to move the Holder about 160mm away from the work area, and park it there. I have a fixture that I place a part in, and bore some holes in that part. Then I swap the part and hit Run to bore the holes again. The last operation retracts the Holder to about 160mm from the work area, then bores a hole in a part I created just to move the Holder away from the work part. That's how made the Holder move away from the work area, since I don't know how to write Gcode. Here's the Gcode for the last 3 lines of the next-to-last operation, and the Gcode for the last operation, followed by the Gcode that Fusion inserts to return the Holder to Home. What should I eliminate so the Holder pulls back and stops without boring a hole? I think I need to eliminate Z6.005 and everything after it.

You don't seem to be using our Post? We don't use G28 docs:software:fusion360 [OpenBuilds Documentation] Use our post if you need our assistance, otherwise if you want to keep using that post, direct the question at the developer of your Post Processor
when using the OpenBuilds postprocessor you can set the ending X and Y machine offsets to put your tool whereever you want it. DO make sure the Z remains HIGH, the default is 10mm below the home position, this prevents it hitting things during start and ending moves. Keep this. Set X and Y to what you need in MACHINE coordinates, you can og to where you want it then hover the mouse over the X and Y displays in turn to see the machine coordinate. Remember that Fusion will recall these values for all future jobs which may not always be suitable, so think about what is going on when posting future jobs.
Thanks Peter, Maybe I should consider using the OpenBuilds Post Processor instead of the one that comes with Fusion. Is there a Thread on the OpenBuilds Forum that tells about the advantages of using the OpenBuilds Post Processor? Thanks, John
Thanks, David This sounds like a good reason for me to switch to the OpenBuilds postprocessor. I looked at Fusion and see that the postprocessor I've been using is Grbl, which I imagine is pretty vanilla. I really like using OpenBuild software to run my CNC machine, so I'm sure the postprocessor will be a step up. John
Hi Peter, I followed the directions above, but hit a dead end when I tried to upload the OpenBuilds postprocessor .cps file to Fusion Assets. In Assets, after selecting the CAMPosts Folder and clicking the Upload Button, the next screen did not show Assets > CAMPosts; it just showed Assets. So I went ahead and uploaded, but Fusion could not find the file. I'll post this to a Fusion Forum as well. Do you know if anyone has successfully followed these steps with the current version of Fusion? Thanks for any advice. John
https://www.autodesk.com/support/te...ll-a-custom-post-processor-in-Fusion-360.html etc - they sometimes change the procedures
it caters for router, laser and plasma machines it fixes small arc errors it reinserts missing rapid moves when needed it does not use G28 but instead uses the industry standard G53 safety moves it can be used for machine simulation it can use a 3d probe for simple probing on a Blackbox 4X (driven by Fusion probe routines), more advanced probing with the X32 is coming.... it puts comments into the Gcode so it is easier to follow what it is doing. it caters for manual tool channges by outputting a file per tool, automatically.
yes, in V1.0.0.38 GitHub - OpenBuilds/OpenBuilds-Fusion360-Postprocessor: Post Processor for Fusion 360 for use with OpenBuilds Machines running Grbl 1.1 and (similar setup for 3axis on the usual postprocessor)
