    2021

    Man, 2021 has been the buggiest release I can remember in years. I'm not gonna nag and complain, as I know software has shortfalls sometimes. I just want CNC to put fourth effort in correcting some of the problems before more bells and whistles are implemented. I do like some of the new paths and geometry alteration methods, so not all is bad.

    If you wanted to get real trick you could set them at 120 and -120 using cut direction and have it go towards the inside. That is the beauty of direction it is like lead in/out for old school surface toolpaths. Linking parameters in the new surfacing toolpaths just don't give us this kind of control.

    On the Surface Finish Contour program I used the Direction check box and set the Plunge Angle to 0, XY Angle to 0 and Plunge Length to .25 for both Plunge Direction and Retract Direction. It allowed me to lead into the under cut without hitting the part.

    Thats great, dont want to have to purchase 5axis just to do an undercut

    Yes.. Front view shows it clearly now If you use that file I uploaded you need to change the tip comp back to tip from center on the Tool Parameters page otherwise it will post wrong and your operator will get a nasty surprise

    If you look on right view during back plot the angle is larger and you can see if it is following the surface, i dont have my computer with me so I cant look at that file

    2021 crashes on fillet

    The update should still be good for your expired maintenance date since you already got 2021.

    The new solid no history option is very useful for my workflow personally, the profile ramp entry is a good addition as well, I can't speak for others but I have gotten much better performance from verify. As for the issues, we have uncovered quite a few, however many of them are expected to be fixed in update 2.

    I agree new threads should be created for each seperate issue, however, there are quite a few complaints I am hearing about the new version,if you hide them all cnc software may miss out on valuable feedback.

    I think it's working, it's just such a small undercut it's hard to see I changed depth settings to Absolute relative to the center of the tool and made the tool shank the same diameter as the shoulder. If you backplot it and check the X values you'll see every step down is a little bit bigger X value that the one before gcode ucut.zip

    Glad to help. Nope. I couldn't either why I threw Morph at it.

    Yes. It seems to have been replaced with a 'detect undercuts' checkbox instead. It doesn't matter if that checkbox is now enabled or disabled, the toolpath just will not drive an undercut surface, no matter what options I pick.

    2021 crashes on fillet

    Ken I agree with your comments..clearly as far as I am finding with the fillet issue there was a problem with the initial release.. I'm not asking for extra features ect with an update just to fix a basic issue which is used dozens of times a day.. Life without this fix to me renders the software useless.. Especially sucks if you don't backup your files when it does crash.. How do I make a case for software fix for this given my maintenance has just expired?

    Machine undercut with lolly-pop cutter

    didn't there used to be a check box that told it not to gouge check.... and if you checked it the toolpath would machine undercuts... the gouge checking was up to the programmer?? I remember doing 1.5" deep angled undercuts with a Ø6" wheel cutter with this toolpath in V9, easy as pie ????

    I had the exact same feeling Tom. Something that I've done successfully, many, many times, and all of a sudden it just won't work no matter what options you throw at the toolpath. Between this, the "trimming" debacle, and the Planes SNAFU, I'm getting a little gun-shy of Mastercam. I hate saying that; as it has been such a great tool in my toolbox for so many years. I really hope CNC Software can work some magic in their 2021 updates, because some of these issues are becoming deal-breakers for me...

    Okay now we are on to the real issue you are running into. I couldn't get Surface Finish Contour to work. Here is the file with Morph Added. Morph Between 2 Curves 3 Axis

    Flowline is crashing my computer, for a simple operation this is being very frustrating

    Or Blend Toolpath. Many options on this toolpath.

    Use Flowline. Turn off all gouge checks. Surface Finish Contour seems to be broken for Undercutting. I have used it successfully dozens of times in versions before 2017. I haven't had to do Undercutting since about X9. I tried it just the other day in Mastercam 2020, and Surface Finish Contour was broken for doing this...

    its still not following the surfaces when i backplot. it cuts the top rad fine, then just cuts a straight wall after the top rad
