I want to purchase a VMC15 that has a problem with something.... it may even be just user error.
The person selling the machine does not know anything about a cnc mill, and I can say, I dont any thing about a Fadal to a certain point.
Here is the problem as I am told....
The machine powers on just fine. Does all jog functions fine. When you power up the spindle, and attempt to go past 1200 RPM, the spindle will shut down.
Now this being a VMC15, I was told today that the 1993 model needed a specific command to get past 1250. Something like S1=1200, but to get to above this 1250, you had to enter S2=2500.... Some machines use this if there is a slave cutter I think, but I do not know the commands for a fadal and maybe this is right.
OR>... my thought is the spindle drive is just bad when it gets to 1250 vs being able to run at 1200 with no problem..
OR> ... I was also told that there is a parameter that can be set to ensure the machine was not run past 1200 if that is the spindle speed needed for that job.
thanks........
