I'm using the current posted haas pre-ngc https://cam.autodesk.com/posts/post.php?name=haas%20trunnion and I keep getting REWIND: Rewind of machine is required for simultaneous multi-axis toolpath and has been disabled when trying to post any continuous code .

HI @Anonymous

Thanks for raising your concern via forum.

You can resolve this error by setting the 'performRewinds' variable to true in the post.

Save the file and test the nc code carefully.

Regards

Hi @Arun.rs it is ignoring that line , mine is set to true and I'm getting

Error: REWIND: Rewind of machine is required for simultaneous multi-axis toolpath and has been disabled.
Error at line: 2665

HI @Anonymous

Thanks for sharing the project and the post .

I got the error message while processing the 'Steep and Shallow1' toolpath.

and the error cleared by setting below condition in post.

var performRewinds = true; // enables the onRewindMachine logic

Hope this helps!

Regards

@Arun.rs that was changed with the same results , the trail has expired . so I can't try again and I'm not sure how I feel about the results I've gotten . I did get advice from someone to use the ngc post and that worked but came up with the issue of slow multi axis moves ( the inverse time ratio in the post being wrong ) . Also there was a few paths that using a tapered ball mill would make sense but all I was an arc error with no clear solution found in the forums .

I guess the only way to get a reply in a timely manner is scheduling a call .

thank you for you reply's

@Arun.rs with me having to restart fusion a few times to extend the addon for a day , changing that line worked for outputting code but I'm wondering if the slow feed is still there . before it wasn't so I'm wondering if the file was no reloaded when I thought it was . I'm testing the code shortly
