Thanks a lot for the help!!!
I'll look at the program and pages you scanned now.
@Hood, I went ahead and threaded at 200 RPM 16 TPI with 8 passes and it came out fine, thanks. The only thing is the last 2 or 3 passes vibrated the machine a ton. I guess it could be one of two things, either my bit is not exactly on center or that's when it's topping the thread. I persisted and reran the program and it did fine. Still a tiny bit of vibration at the end of the run, mind you I do 6 spring passes to clean it up so it's probably just rubbing.
Two important questions, will upgrading to the newer Mach mess up any settings, macros or VB buttons I run? Also what will exact stop do for regular lathe work when not threading, do I keep exact stop on all the time? Thanks again.
You may need to upp the passes a bit but personally I would cut down on the springs, I normally only do one but again its all dependant on your machinery so messing around with things is really the only way to find out what is best for you.
Shouldnt have any probs with upgrading, just make sure you have any custom things backed up first just in case the worst happens.
