Ok, for all you guys using Fusion 360... I have four projects sitting in Fusion 360, completely designed and CAM'd... What are the correct post processing settings to use with our machine?

I'm guessing "generic grbl"... I ran that, and imported it into CAMotics (virtual CNC machine) and it ran the file without issue... Will that work with our machine as well, since it's also GRBL?

Nevermind... I posted before I checked Derek's guide... For anyone who reads this later, just completely read Derek's Fusion 360 guide on the website, under the Resources link... Then, read it again... And probably a third time for good measure...
Thank you Derek for making that available. Sorry for clogging up the forum with my boneheaded question, LOL...

Making my first Fusion 360 cut... It sure seems like Fusion is quite a bit more aggressive with cut depth and speed... But all seems to be going well so far...  Fusion by Jason Lindsay, on Flickr |

It's only as aggressive as you tell it to be. You can change maximum step down and speed for each path you set up.

Ahhh ok sorry. Yea it definitely does things with more purpose than easel. Were you inputing spindle Speed and chipload then letting it calculate feed and surface speed?

Also, don't forget to raise Z height before sending the go command. Lol. I've created that diagonal line more then once.

I know how awful this is going to make me sound... but no... I was putting in spindle speed and selecting my bit. It figured the rest, LOL... There's SO MANY options in Fusion, I still have much to learn. I'm just glad I got it to make the cut I intended it to make, other than that diagonal line... J |

J When you do the post process and save the Gcode, go in and edit the line that says "G54" to G0 Z10. Should be near the top. That will raise the z height up 10mm before advancement. Handy for when you forget to raise it up after setting zero. It's habit for me now. I usually focus on spindle Speed and chipload and let Fusion take care of the rest. It's pretty good about picking the correct feed rate. Obviously you can adjust based on material you're milling. |

I guess I need to find, I'm sure somewhere on this board, how to calculate chip load... LOL... J |

It's in a collaborated edit stage at the moment making sure we get the right info to y'all the right way. I use the charts on this website for my baseline chiploads. www.harveytool.comJust go to products, find a bit similar to yours, click chiploads tab and do some exploring. Chiploads are set by manufacturer based on material and cutter geometry. |

One thing you can do though is just edit your code and add a Z lift prior to the first XY plane rapid. Yet alìother thing you ) is just to raise Z an adequate amount prior to pressing send. You don't have to be at 0,0,0 when you press "send". It could be it 0,0,35 or 9,-3,18 for instance, and it will still be referring the origin you specified.
