been having a problem with y axis disconnect on a fanuc o-m controller. It is a problem that has been happening for a while. I have been doing the p-cancel button on power up. But today it took about a dozen tries to get it to zero return.
Once i ran a program the first time it worked fine. The second time it seemes like it lost all idea where it is in the y axis. Nothing i try now seems to work. I shut the machine downand re-zeroed, but all that happens is a random tool path.
Any ideas? Thanks
