Project Curves offset issue

[Metallic]

Doing another multiaxis engraving job...however with Mastercam 2020 I am having issues with negative drive surfaces offset values. Positive values or 0.00 values generate a toolpath fine.

I opened a 2018 program i had written using the same toolpath and it does the same thing when you modify the already existing negative value from that old program file.

 

Is this a bug? I think so.

No one?

I took a look.  Idk what's up.  I was getting that with Curve as well.  I've been using curve for 4 and 5 axis engraving lately - just seems to serve me better. 

 

Tbh I gave up because there were no machine files and I got frustrated clicking ok so much.

Here's a sample using Curve, no surfaces at all to worry about projecting to.  Idk what's up with that solid but I had to get excessive with the lines imo to get it how I'd run it.

yes this is a problem I have been facing lately. I am not sure how my config transition to 2020 got so effed up

seems that it doesnt like center drills 

if you change to a ball mill it works right away

Yea, that is weird. I can't be the only multiaxis user who engraves using solid carbide center drills so hopefully it gets resolved but we will see.

It works just fine with a ball, so I will do that in the interim. I may submit a bug report.

I prefer Project Curves over Curve if I have the choice.

 

Thanks for the help guys

Thanks for doing that, I took a look at it and it works perfectly.
