Remember Mastercam filtering has been and is still tore up from the floor up. Simple test make a 100" diameter sphere and then flowline the sphere with a 1" ball endmill. Throw as many filters as you want at it. See which one gives you only 100% arc moves for the cuts. I have ran this test on every X version since X came out. Not a single version can give me 100% arc using filters. I have backplot the toolpaths make arcs and run a Contour toolpath with no comp and guess what the code never matches. This is the math test the filter fails every year. Just ran into using 2D Peel on a 40 year old machine. Wanted the smalest amount of code possible. What does anyoen think gave me the smallest code out Mastercam? . . . . No one willing to guess what filter settings gave me the correct code? . . . . . Come on no one is willing to guess? No filters gave me the best code. Now no filters on a 3D toolpath doesn't behave the same as with filters. Let me repeat that no filters on a Peel mill toolpath gave me the cleanest code with all the arcs and line movements. With a filter it was junk IMHO. Now 3D toolpaths don't behave the same way. Screams fundamental math problem somewhere and for over 15 years no one has dug into why. I am the crazy person on the forum so I guess there is that to consider I mean we all know math is about feeling and mood swings. No way I should expect a G2 and G3 to be just that they can be whatever Mastercam decides it wants them to be and just keep your head down and go along with the idea it is good and it is good.

This thread made me think of this very useful old Camistructor video. I always forget these toolpaths are available.

True dat.. If it doesn't work, they shouldn't be selling it,,,, and they sure as hell shouldn't be calling it "turnkey"

Didn't Bob W have issues with DMG and MillTurn dating back a few years or more?

Every day goes by, is a day too long. Both DMG and your reseller need holding to account....

Thanks Colin. I appreciate the tool recommendation.

I don't have a CTX handy, but I just did some MT programming for an NTX (to be honest, I'm not sure what the difference is ). When I posted out the code, it will generate a "-upper" and "-lower" version. For example, here's a file 0009 posted: Unfortunately, that's where my knowledge of 'em ends, as I never actually ran one. From what I can tell it was out being output correctly, though, the setup guy/operator I was working with seemed happy enough? If you could post a sample file (zip2go so we have the machine def), we might be able to help specifically. You may already know this, but it chooses the "stream" to output based on the individual toolpaths' "Axis Combination" selection, i.e.: So anything happening on the lower stream has to be programmed to Lower Left/Right. I've seen a lot of old school lathe guys getting into MT forget to check this, as they just set everything up to the Upper Left all their lives.

Why not? It sounds like they stole the money, got into the car turned the key and drove the getaway car..

Wait....you mean Mastercam ISN'T malware?????
