I do use RTAI with my Sherline 2000 micro-milling machine and steppers. I understand that maintaining compatibility with old hardware could be too big a burden, but so far it's what works best for me. Since Sherline used to sell his CNC-ready machines optimized to use LinuxCNC, I guess i'm not the only one in that case, but I could be wrong.
Should RTAI be deprecated, I would really appreciate some documentation about getting good performance with that hardware.
