Thank you guys for the help. I did try some of your suggestions and I got a toolpath that I was happy with that ran good in the machine.

This is the method I have been teaching customers to use. Each tool and holder will have it's own sweet spots and defaults from Material are not as refined for these situations as needed.

Those Makinos like lots of points. If you have any tilt at all, consider dropping your Max Angle Step on the TAC page from 3 degrees to 0.1-0.5 degrees.

I seem to recall some members having issues with setting this up, some one else might chime in with what the issue is. I personally use speeds and feeds from tool and have created tool libraries for specific materials, i.e. ALU , different carbon steels, Stainless, etc, etc.

In-House Solutions is excited to release all of our Mastercam 2023 training material free of charge. You are free to download the pdf training material and Part files but check back often as we do update this material regularly. This is the same training material we use in our training classes you just don’t get the expert trainer to walking you through it. https://www.inhousesolutions.com/resource/mastercam-2023-training-links/?fbclid=IwAR37BKhkMZ2SFG6_3x2l54fH-hdj9hCVQti4mQtgs0mPhoYu_uPEH1h_SYc

Try changing the Projection direction in "Guide Curve-Advanced Parameters" to Machining direction, and change the "Tool Axis Control" to Tilt angle from axis towards point.

Haven't got a lot of time to play, but if you turn on some collision control you will stop the cutter trying to cut through the surfaces. Also looks like a crappy surface to program from !!

Is it possible for you to share the file? Even just a sample file with a mock part would be helpful. I'm not exactly sure what you mean by "undercut". Can you see the undercut in Mastercam verify? I'm not sure how step up would benefit here, but I can't clearly see the application either. Here's some reasons step up may be used: 1. you have an existing pocket and want to start at full depth and work your way up angled walls / surfaces 2. you want the tool to use step downs and after milling at each level it will use smaller step ups to rough surfaces closer to finish I'm sure there's countless reasons to use step ups, those are just off the top of my head.

For sure. I'm just bummed about them no longer tweaking post even though I'm current on maintenance.

the new forum will fix these issues along with the connection issues in the 4th quarter of the year i think, we have to wait till then, there is a timeout on the forum when writing messages, if its going to be long you would have to write it in word and copy it over, or be a little less long winded... haha jk jk
