Fusion 360 Post Edit

Post by justcrankinit »

Can I modify the Fusion 360 milling POST to include a dwell time, the machine is moving into the part before the spindle has reached the appropriate speed.

I have been able to manually add a dwell time but hoped I could modify the post. N36 G4 P5 is what I used for the dwell

If you modify the M3 macro, the dwell will be there no matter what post you use, or where your code comes from.

I'm a firm believer that you should modify macros for machine specific behavior and not posts. If a particular machine takes a certain amount of time for the spindle to reach speed,or needs to orient the spindle for tool change, those actions should in macros for that machine.

That way you can run the same code on multiple machines and it will work right - waiting the appropriate amount of time for each individual machine. You can run code a friend gives you and not have to remember to add a spindle dwell.

Of course, you can modify the post to add a dwell if that is what you want. F360 posts are fully customizable.
Cheers,

I modified the Fusion 360 Post Processor to add CNC12 specific features and it does have a Post Processor Property that allows to add a dwell factor and the dwell time will be calculated based on the demanded RPM of the tool.

The Post Processor can be downloaded at the bottom of this Post.

Checkout the Enhanced Fusion 360 Milling Post Processor for Centroid CNC12 User Guide for all the details of the Post Processor.

Thanks @swissi! I saw this in earlier threads but hadn't tested it yet.

As noted you can also just modify the M3 macro by adding dwell time. That is what I did long ago and has worked great.
