Maybe a 5hp motor?
Slowly git'n worse, and soon to be beyond useability I'm guessin'.
It just aint smooth. It is very rough.
I liken it to the time that I had the rubber star/bushing in a small Lovejoy type fitting come out (disintegrate?) on a 40hp DC motor, and it was erratic to the point of making the RPC on the other end of the shop dance the jigg!
The spindle does have a belt driven Heidenhain encoder on it - but I think that it is likely only used for C axis.
That encoder does need replaced as the HOME pulse is bad, but if I run it in INCR, it is fine, so ...
But I am guessing that there is a tach up inside the spindle motor.
It seems to warm up and then work better, but ....
From anyone's experience here, what is more likely the problem?
The tach being bad?
Or the amp getting bad?
