Hi!!

Maybe some smart head is able to help me - I work at nakamura tw-10 - first operation face off then I have to engage c-axis (left turret) so I use M91. Next operation milling c0, c90,c180, c270, part is quite simple.
the proplem is after turning chuck is in "nobody knows" position, I write M91 and g0 c0 to rehome chuck but it takes time, sometimes after turning I see c axis in 450deg. I cannot wait 3-4 sec. until chuck will be back in 0. Maybe someone knows how M91 works, I need details or some way to fix the problem and make it shorter.
Thank You Guys
