Thanks. I ran QTvcp-Screen-qtlathe sim, accepts T0101 and no error message. industrial_lathe_wear.ini has same remap T and M6 functions as lathe.ini. The stdglue.py file seems to correspond to the industrial_lathe_wear.ini and maybe some other files. QTvcp-Screen-qtlathe a little oversize and requires to pan to see buttons. Offset button nice but didn't appear to have a column for tool nose radius. A step button doesn't look visible. Programming D_ to enable tool nose compensation and running program looks as if not compensating. Dynamic tool nose compensation might not enable either. Also, nose radius of tool not adjusting to D_ size.
