Some time has gone by now and I'm still calling subs to get the results I need. Things work well that way but I stumbled into something yesterday. The attached code runs on my laptop using R3.043.022. The computer running my mill is version R3.042.040 and will not run the code. Maybe the cutter comp with work offsets has been repaired....not sure. Can someone else give it a try and confirm this for me before I go running updates on the mill computer. Thanks, Riley.
