Hello and thanks for having a forum to ask questions. I am new here. I am working second shift and its hard to get day shift to get things worked out. i am working on a new retro fit with a fanuc oi-md controller. The main problem i am having trouble with is the tool offset. when day shift set the programs up they call up the the tool by using G43 H1 Z1.0 . it calls up the the offset and runs fin except that in Absolute Z shows up as the Actual Z plus the offset. so if i have an offset as -2.5 and i have it zeroed on the face of the part when z goes to the face it shows as Z-2.5 not Zero like it should. when i change the command line to G43 T1 Z1.0 it looks like every thing is going to work great. it calls up tool 1, changes the offset properly and moves to Z1.0, then will not progress to the next line for anything. no error. just hangs up. the machine has a tool changer. but is not operational and is cut off. not sure if it had anything to do with it. but what ever line the T is in that is the where the program stops. any help would be greatful. i just want my Z to show up a Zero.
