I am retrofitting a lathe and need some information as I have been away from the forum for some time and have not been following along
thank you

Archie,
Retrofitting a machine means sometimes getting extremely intimate with a machine. Haha.   I know that only too well.   But it depends on the motors and drives amd their compatibility with the motion controller you choose, whether you replace them or not.

not wanting to muddy the waters ( this will be for another thread)   i have 6 ea  140 volt dc brushed servo  motors and 1 larkin 200 servo drive  for a mill and other projects

Chad.
         I did some measuring today and it looks like the 19 inch monitor  that I have will fit in the space  where the monitor goes on the lathe and possibly a small form factor PC behind it .    otherwise I want to rename this thread "poking around in the dark".  It looks like I am going to have to pull alot of  the guarding off of the machine to get to the motors and wiring. I guess I am  going to get way more intimate with this machine than I ever wanted to,  like with another brand new manual machine i purchased the the same time i got this Lathe.  A story for another time.

Happy Hunting

Chad Byrd, I have an electronically dead Nardini 17 x40 in my garage, 20T Fanuc on it.  id really be interested in hearing everything you might be willing to tell about your lathes, probably with the exception of the GSK unit.  im thinking steppers myself, or finding some DC servos very similar to the ones on my (also electronically dead) 3 axis cnc acra turret mill knee driven, so I can use them across both machines.  if anyone else has comments also interested.  perhaps send by pm so as not to muck up Archies thread.  engine lathe no tool changer.  I will be looking primarily at PMDX or the UC controllers.
  If I were looking to replace what I had on my lathe (which I am not)  I would only be looking at ac servos which are step and direction   like the cnc techniques or the dmm units   In my case the servos and drives are new which makes me very reluctant to tear it apart  archie :-)

Pretty nice looking lathe. 
Hopefully you will be able to use the existing motors and drives. 
The first PLC I used, we programmed a Tool Change Routine for a Hurco VMC; so it won't be too bad. 
Luckily, on your lathe, you have a nice control panel that already has the handwheels and buttons on it, we had to make ours.
Chad,
          what Plc's are you using with the integra and how did you figure out / learn how to program them

thank you

Well I had to make one of the "hand wheels" what holds the encoders  it had only one.   I will round  up a couple of photos and post them   Manual lathes and a drill press.

One lathe has Servos and Drives from Automation Direct, one lathe has GSK Servos and Drives, and another is just running steppers.  All with the HiCON Integra.
We have an SL3 that me and my brother want to get the closed loop feature added on to just to see what kind of difference it makes, but we have really had great success with all 3 lathes without the closed loop feature.

Most of our I/O is being controlled through a PLC.  Much more stable signal and if I have any random ideas for the machine, I can run them through the PLC and not have to worry about Mach taking care of trivial things, like the lube pump or chip conveyor.

chad,
      i am going to pull some covers today and verify the loop was closed at the control  all servo systems have feedback it just depends on where the following error is monitored  at the drive or closer to the computer I would think that the harder you drive a machine the more you might see a difference in behavior. I am going to attempt to use the drives and servos  that are on the machine they are new.  the machine has  or had a PLC in it somewhere. All of this is going to be a steep learning curve for me.   mach 4, servo systems,  PLC  ect. screen writing maybe

steve   $#(#$)()    No threading that is a deal breaker for me any idea when it might be implemented.      i think the drives have analog inputs 

Well...  I pretty much need a lathe that has a Galil on it to implement and test the threading.  I had started the conversion of my manual lathe years ago just for this purpose.  But it is not finished and probably won't be for a while because I really just don't have the time to get it done!  :(

Kenny Crouch, the other programmer on the Galil plugin, has moved to St. Thomas Island in the Caribbean and could not bring his lathe with him.  So...  we just really don't have any machine to test with at the moment.

Steve,    how much of a process is it to get the plug in to work do you just need a guinea pig  8)

We have 3 lathes running Mach4; 2 of which are flat bed lathes.  I chose the HiCON Integra from Vital Systems as my motion controller.  I'm using that on several machines in the shop with excellent results.

One of the lathes we have is an old LeBlond that was a manual lathe, we stripped the old drive stuff off of it and added ball screws to the X and Z axis.  I added handwheels on the carriage because it is over 60" long.  All works very well. 

I don't have a tool changer on this lathe, but I have one on another lathe that is working great with Mach4 and the HiCON Integra.
Long story but I have 2 lathes and a mill  the two lathes have the fagor controls on them. they have Fagor servo amplifiers loop is closed at the control not at the servo amplifiers. after looking at the Hicon documentatuon there are extra units and software options that have to be paid for anyway what are you driving with the hicon boards.
