I must be missing some context here. I have been feeding back for
spindle speed control, an encoder generated ABX set of quadrature
signals generated by ats-667's which are watching the spindle backgear
teeth go by, for about a decade. What has the presence or absence of a
v-belt in the path got to do with it?.
Cool!
I have the same doubt about the kind of belt I should use. In theory,
several V belts well tensioned should work perfectly without slipping and
the encoder on the spindle (this one of course coupled with a timing
belt)
should be able to keep up with the position and nothing should go wrong.
The lathes we have all work this way and I have never experienced belt
slipping. But for some reason I feel more confident using timing belts
all
the way. I don't know if this is an overkill and I should go with the
simpler V belts. Remember that this machine is going to be grinding cams
and eccentrics.
I have done that, but the spindle speed is suprisingly slow if X is slow.

Is there a place to get that file? Because I couldn't find it yet.
