I am very happy with Peter's comments on the handling of Index and polarity.
On frequency, my calcs. are like this:
Lathe: Spindle speed up to 3500 RPM. Threading and tapping will be slower
than this but very handy to have actual spindle speed display of whole
range. Encoder at 500

One comment I'll add is the gremlin back-plot display seems to interact
with the X-Server and add significant lag to keyboard jogging (at
least the way it's setup by default).

It is configured with a geometric speed law on the spring-loaded ring.
You can jog at full rapid speed slowing to a crawl allowing touch-off
to a tenth very quickly and safely compared
Jumping in - I have had this with the MachineKit. No noise but as I had the
'scope on the signals I spotted the fidgeting Dir. I had no pulses on Step
line, just Dir hunting. I was worried that it might stop the stepper drivers
going to reduced current mode but with the ones I was using this was

Not Geckos here but a Leadshine 3 phase stepper motor driver.
I think John K has covered more bases than I ever could.
In essence I see it as the accumulator counting up and down but not
overflowing so a step never gets emitted but the sign of the error is
changing so Dir follows this.

This is probably a question for PCW but others might know or have dome it.

The BLDC motors suit a 7i39 very well (interfaced by a 5i20). Are there any

Yes you can look at the 7i39 as 6 individual 1/2 bridges and drive 3 DC
motors from one 7i39. if a brushed motor was connected to half bridges A and
B, I _think_ what is needed is to drive A with the PID

The Manpage of Hostmot2/Encoder defines a pin:
(bit in/out) index-enable
When this pin is set to True, the count (and therefore also position) are
reset to zero on the next Index (Phase-Z) pulse. At the same time,
index-enable is reset to zero to indicate that the pulse has

John, thank you for your elaboration.

To extend the wire-signal analogy, I think of I/O pins as tri-stateable
signals.
I don't really get this analogy as there is also a memory hiding somewhere
for when everyone it tri-stated. It feels more like a wire with
