Is the High Speed Machining option needed in the Haas Control to run Fusion 3D tool paths like adaptive clearing? What are the benefits of the HSM option?

The tool path can get quite jerky when going at a high feed rate without having that look ahead feature turned on. I've never used Fusion but in Mastercam, you can mitigate that issue somewhat with 'Arc Filtering/Tolerance' which reduces the code. If you're cutting softer materials on the daily, I suggest paying to unlock the code, otherwise if you haven't turned it on, you get a considerable amount of time to try it out for free, think its 1000 hours.

Thank you for your response. You can get 200 hours of use before having to pay for it. I'd like to see the difference on an an actual part and machining time difference of the two. I am getting close to making a decision on a mini mill or mini mill 2.
