I think that the servos + resolvers will work a fair bit better than
steppers. I was rather upset when I found that my ebay bargain servos
had resolvers, but now I am something of a fan of the devices.
I have to agree, if they are used correctly with good electronics to
drive them,

It might simply be because resolvers are analog which considered to be old
technology. It is useful to have some extra resolution above the accuracy for
the control loop and I think resolvers usually have higher resolution.
I read many times digital control loops are faster but quite a lot of

True, I ended up writing the Mesa resolver and 3-phase PWM drivers and

Hi,
200V @ 10A with resolvers looks like a good candidate for my brushless Driver.
We are making very good progress at the moment.

Will the parport be fast enough for this driver or does one need special
