Hi Mark,
I have a old SBL Magnaturn that uses KMotionCNChttps://www.cnczone.com/forums/dynom...-retrofit.html. There is some others that have CSS working, but i gave up on it, the machine was to tied up to keep trying to get CSS working. Currently the Fanuc cycles are not supported, unless Tom has recently released a test version. The way KMCNC is programmed is more like a mill. As it does not support certain things like tool offsets calls, like most lathes. Most lathes will apply offsets like this T101. Which is Tool1 offset 1. KMCNC lathe is like the mill M6 T1 with a G43 G0 H1 Z1. Right now i use Fusion360 to program lathe. Also have latest BobCad with lathe that works nice also.And just recently purchased Ecam https://v4.e-cam.it/, have not used it much but so far is really nice for programming lathe.You can also use it for free on the weekends.
