Hi Chris:
Actually, there is a difference, sorry I meant to get back to you. On the diags page are three new DRO's that show the abs mins and maxs computed. Tell me what they say whgen you get the error. Also , resend me the file you were using, I have lost the original. I need to know how the min and max numbers shown relate to your machien coordinates.. IT seems to only happen in G43 moves, but Im stiull unclear exactly which ones..
Thanks
Art
