we don't have an MC page and the head stock doesn't move, the carriage is sent home. I'm assuming the machine length is set buy the g50 and how the program ends. Your asking the same questions I've been asking..my problem is the book doesn't show the answers. All of our errors are happening because we are setting each tools offests correctly and now the program wont work because of the corrections. The guy who used to run it just brought the tools down close with linear moves, then would add offsets to get the tool centered which worked but not correctly.
