Don't worry about the G50 input, things like that happen.
I don't know Bob CAD/CAM so when you post machine code from it send me a private email with the code & a copy of your drawing or sketch attached and I will be happy to look it over and check it for you. Sometimes it helps to have another set of eyes checking the work till you get error-less code to the machine.
We owned a couple of those old dinosaurs. One thing I remember is the X values are all negative. For example: turning an 8 inch diameter would be X-80000. Trailing zeroes, no decimal. I also remember the square, white buttons popping of at will. Heavy duty machines, we did a lot of hogging with them.
You just had to do it didn't ya, LOL, ya had to give Cliff a little more information.
Cliff didn't know the controller ignores + or - signs when programming SFM. He thought if it had a program point of X-.030 when you approach X.0 and pass it to a X- value that the machine would stop and reverse spindle.
I don't want to clue in the clueless but maybe he should note that as the tool approach;s X0.0 that the spindle speed is already clamped by a G50 S value input or the machine's max RPM.
Think how surprised he will be when someone lets him know there is NO G40, 41 or 42. Oops, did I say that? Now there are more cats out of the bag.
LOL, Tom
Although I may have given him too much information already to the point he can BS his way through it, I Still am waiting for Cliff's;
