the puma lathes are perhaps the easiest lathes on the market to realign. I have not done one in propably a year so i hope i tell you this correct. if i am off on anything it would only be a keep relay as i believe you will use K5.4. any how turn on your pramater write enable then if you have a lot of heavy tools to one side you will need to hold the turret in place by hand while you change keep relay 5.4. this keep relay is installed in the ladder as a way to manually clamp and unclamp the turret. while it is unclamped indicate the turret into place. i believe the books allows .003 tolerance however i prefer less as it makes programmers life simpler. once you get it into place by manual turning it by hand into place then clamp the turret. it should clamp claen and not move in ccw or cw direction if you have the gears lined up properly. the only thing i would check is your keep relay list as i am quite sure that it is k5.4 and often people change k5.5 which tells the machine if it has a turret or not. these are the only machines i have that you do not even have to break a bolt loose to align turret. if you get it clamping good and can not find a spot on the clamp ring that allows proper alignment then you may have to go farther and let me know if it comes to that and i can address that to. i wrote the ladder for one of doosans new automated inverted lathes for the former automation group in detroit so i have become quite familar with these machines.
