Hi:
>>The problem now each time a new pass starts, it starts just a few degrees later . On a 3-4 pass thread 40 tpi or so you can only see the problem under a microscope.
This is an odd problem to have. (Though Im pleased pitch and such isnt a problem on either lathe, but then it really shouldnt be.). This new thrust is really meant to help
in compensating for computers that vary their internal timing , it is thought ( primarily by me.
), that many of the issues with threading are a result of internal clocking
differences in some CPU types and motherbaords. The new plugin is goign to try to address those by getting more accurate data from the cpu and motherbaord and
allowing a better averageing of these random frequency changes. When you average a true random event, you average to zero displacement. So a multi slot
system ( say 90 slots in a rotation ) should be 64 times as stable ( I average over 64 slots in the driver ), and more responsive as its correction algorithm will use a rolling
avergae over the 64 slots so even one slot timing changing from a load will compensate. In theory all this will help.. a lot if Im right, not at all if Im wrong.
Your problem though.. cant see it. Either the license file is acting up ( make sure it doesnt read demo..) or the "Use Spindle Feedback for sync" isnt checked. The only
other possability is a floating time on the trigger (index) pulse or a computer that is internally floating more than most. Almost no reports have ever been made of start
trigger fluctuations though.. normally errors are in the pitch realm, but from variations during cut, not from the start, on 99% of systems the first several threads are
near perfect. There arent enough users to give you stats on how many have issues with threads, but I hear from fewer with problems that I do from people with
threads that are good. Within a short period though I will turn on the compensator algortithm with this current testing.. and we'll see if all is well , better, or worse
with this theory.
Thx
