I like the Polish "Not My Circus, Not My Monkey".
I'm trying to get up to speed on what a mill fourth axis presentation
should be in the LinuxCNC backplot (Gremlin).
Currently, any rotation of the A axis either rotates the tool centered
on the control point, or rotates the tool around the control point and
then around the machine X origin. I h

I just remembered that Granite Drives have a (very cheap) adaptor to
allow use of Resolvers with the Argon drives too.
You would almost certainly end up using step/dir co
Hi,
200V @ 10A with resolvers looks like a good candidate for my brushless Driver.
We are making very good progress at the moment.

That's interesting and opens up the possibility of using a number of
alternative drives.
However
I have a feeling that these have resolver and hall sensors as there is
huge number of wires on the plug. More that what a resolver will need.

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

I will have to look at Jon's stuff as well before I decide. Thanks for

That sounds a lot like what I have on my mill.
Pico-systems have a 160V / 20A servo drive that can probably be made
to work along wit

I initially wrote the component to support the 7i39, and then extended
it for the 8i20, so its main use is for Me
If the parport is not the best option, what would you suggest? One
obviously is Mesa but are there others that you know of?

It is possible to use the parport. Someone has managed to spin some
Fanuc motors with the Parport and AMC drives.

Will the parport be fast enough for this driver or does one need special
hardware? If so, what is recommended?
