Regards,


Continuing the search for the solution to the problems of my lathe.

The posting for inspection, test, criticize or improve.


At the moment only for external profiles, unfortunately not modal, for now.
The constant cutting depth, the depth varies agree programmed cutting.

I have some concerns that I could not solve,


1) when an error in the programming and chasten the program does not take change well, I have to close and reopen LinuxCNC, so assume correctly.

2) how I can make modal coordinates??? they are not repeated in each block.

3) I hope some suggestions to get better work.

This looks interesting. Have you done some more work on it? Have you solved the bugs? How do you handle pockets?

Nice work! And maybe an even better idea to tell controller about profile shape!

I think every lathe user should take a look at this, it generates roughing and finishing paths directly from DWG file, really nice work there! Thank you for sharing this!
