My VMC (Makino FNC-60, Fanuc OMC) has some strange control quirks, and I was wondering if anyone has run across these, or might know how to fix them.
For starters, if I stop the spindle mid-cycle, I am unable to re-start it. Is there a special button I need to press in combination with "Spindle Forward" in order to re-start it mid-cycle?
Secondly, pre-loading tools does not work on this machine. The machine has a side-mount toolchanger, but it freezes up when you call a tool which is already in the ready position. It does not throw an alarm or error or do anything at all. It just indefinitely stops executing the program. I have been working around this since I got the machine, but it's getting old, to say the least. The following code is an example of what freezes it:
N05 T1M6
N10 T2
N15 (T1 program)
N20 T2M6
N25 (T2 Program)
N30 M30
On the first execution, this program would freeze at line 20, before executing the toolchange. On subsequent program runs, the program would freeze at line 5, because T1 would already be in the ready pot from the toolchange at line 20. This makes running 2-tool programs annoying, since I have to add an extra tool-call at the end of every program.
Thanks in advance for any help. These problems are minor and stupid, but they are getting old.
