Jeff, Thanks for the response. I guess its not as simple as I had hoped. As you have probably already guessed, I was in the process of trying to do a little lathe work on my mill by writing some programs to utilize the rotary axis as the lathe spindle. I guess this is just one of many reasons why everybody isn't doing it. (I haven't completely given up yet)
The only real problem with the "windup" and "unwind" situation is the amount of time it takes to unwind. It is exactly analogous to using a late to thread with a threading dial (cut, retract tool, drop halfnuts, move carriage, repeat) compared to cutting threads without threading dial when you must leave the nuts engaged while you reverse the spindle and turn it the same number of turns you used while cutting the thread. It is just time... and someone, maybe my granny, once said "Life is just time and money, either one can be traded for the other" I always put a "cleanup" section at the end of my programs where I set the axes back to where I want them to be when I open EMC the next time and there I also set all the variables that I used back to zero. If I put the G92.1 command in the "Cleanup" section of the program that used the G92 command will that accomplish the same as putting the G92.1 in the "setup" or preamble of all the other programs?
