Autodesk Fusion 360 settings to park the head home after a job

CAD (Design) Software Fusion 360

(This post is to improve SEO and builds on the Parking Position GCode post.)

The default home position that the Onefinity CNC wants to go to is the front left (X0,Y0 coordinate), which in my case would mean the dust boot would crash against the rack I have it on. So I’ve been searching for a way to set up Fusion 360 so the head moves to a different spot when the milling is done. There seem to be two ways to do this in Fusion:

Method 1: Change the Kinematics Home Position:
You need a machine to simulate, and Fusion doesn’t have a Onefinity model in it. (Someone made one and posted it to the forum.) But you can also use the Autodesk Generic 3-axis Router.

  1. In the Manufacture tab, create a new Setup
  2. In Setup > Machine, click Select, Fusion Library, then choose “Autodesk Generic 3-axis”
  3. Back in Setup > Machine, Edit the machine
  4. In Machine Definition > Kinematics, edit the X and Y “Home position” values
  5. When you do the “Post Process”, choose the generic machine
  6. Check the GCode and you should see one of the last lines to look like: “N100 G53 G0 X381 Y279.4”. (In my case, I set the position at X15" Y11", which is 381mm 279.4mm in metric.)

Method 2: Edit the Buildbotics post processor:
This method doesn’t require a machine to simulate:

  1. When in Manufacture > Post Process, leave the Machine default
  2. For Post, open the “Fusion library”, and copy the post locally so you can edit it: drag the Kirbre Enterprises Inc. “Onefinity BB Builbotics” to your “My posts”
  3. Right-click edit the Buildbotics post and it should open up in a text editor
  4. Search for the text: /* home positions */
  5. Remove the // comment in front of the machineConfiguration.setHomePositionX and machineConfiguration.setHomePositionY
  6. Change the 0 to the position you want (e.g. 15 and 11 in my case)
  7. Check the GCode and you should see one of the last lines to look like: “N100 G53 G0 X381 Y279.4”.

Happy carving!

I also did not like the machine returning to machine Home upon completion. But, I found an option in the post-processor of Fusion that allowed a change to the M6 command upon completion. Now it retracts to a safe height and stops instead of going to Home.

I was going to suggest the post processing function. Alternatively, some crafty individual could mod the community Fusion PP for OF and add the ability to select the final destination. That’s been on my todo list for long time :slight_smile:
