Hello all,
I have recently acquired an older import vertical machining center equipped with a Fanuc 6mb control, tool changer and a 4th axis, I can successfully index the axis in mdi, home it out from what I can tell (the home light does not light up after it appears to have homed itself) and i can rotate the 4th wherever I like with the hand wheel, however i can not for the life of me figure out how to command it to feed in mdi or in a program, it just sits there whenever it reads the command and does nothing, since it was equipped with 4th axis card from new, (as far as i know) and has a hand wheel that i can manually rotate the axis without commanding it in mdi, I had assumed that it was like other machines i had encountered in the work place that if you could move the 4th axis with the hand wheel, they were considered to be a full 4th axis, but if you could only command them to index in mdi, then they were considered an indexing 4th axis, am i totally wrong with this theory? Am i missing something? Are my parameters set incorrectly? Also how can I disconnect the 4th axis in the future, from what i can tell the machine was not equipped with the famed "4th axis neglect" switch in the electrical cabinet.
Any help would be greatly appreciated!
