LOL i still have 1.56v on the vfd line. it has 13v input on the bob.
somehow the vfd run that at full power and .75 ish at half power.
is there no sense to this?
whatever! it works good enough to make parts................................

well, it looks like that method worked now that i deleted the linear thingy.
i got it working at about 2% of the s speed.
what was the linearity.doc???????????
thanks fellas!

so if i set the pulley to 1000 and say s1000 on the mdi, i should get 10v at the bob vfd output right?
is there any parameter that could affect this ?

with the pulley on 1000
motor tuned to 60 step / full velocity full accel / 1 in both pulse boxs
the vfd comes down about 180rpm
