CRC programing with an old Fanuc 11M controller

[Moparmatty]

I've been away from CNC machine for about 4 years and the show I work at just got a CNC mill. The problem I am having is that I can't get the cutter radius compensation to initiate. The machine has a Fanuc 11M controller. I'm not sure if I am inputting the radius offset in the correct location. Do I just input it in the same offset pages that I use for tool length compensation?

EG. using tool 27 I'm using TLO H27 and CRC D77. H27 being -10.000" and D77 being 1.000" for a 2" dia. tool. Our machine has offsets 1 through 99 but Im not sure if there is a separate offset page for diameter offsets. Can anyone help me out?

I am not a machine operator but I believe the D offset is picked up by the G41 or G42. or are you already using this?
What was wrong with the servo's, by the way?

I got the CRC figured out. Thanks for replying Al. One of the boards in the back was faulty. We're running the y axis off the A axis board until we can get a new board or this one repaired.

You should only have to enter the radius value into the offset page (after the R or T). It could be possible that the parameter for tool comp is not turn on. I think it is Parameter 907.6.
