Stephen,
I have the same issue and haven't been able to find a solution when I
upgraded from 2.6.8 (?) to 2.7.0. First I updated the firmware on my 5i25
& 7i77. When I would run 2.7.0 I would get the following communication
error.

Ok, updated the 7i77 per your instructions. That seemed to work. It got
rid of the messages when 2.7.3 starts up. So far so good,

While the index will be in the same place, any tooth form error will
affect hobbing.

This might not be as critical as it seems, as the index will occur at
the same point with the same gear teeth in contact every time.

I *THINK* if you incline your resolver gear you can use a straight cut
gear. IIRC, the sum of helix angles must add up to the shaft angles. In
your picture the shaft angles are 90deg so one helix is something like
80deg (the large gear) and the other is 10deg (the small gear). You can do

An alternative to this if the disparate sizes of the machine and the

Haas cnc mills use a kitchen stove top heating element
for their spindle braking resistor. The smaller diameter
elements are about 45 ohms, and the bigger ones 27 ohms.
Wattage is over a kw, as they run at 240vac. The resistance
is a bit low for a capacitor discharge resistor, but at the

Clever.
Doesn't really need to be 1:1. If the spindle makes 2, or 3, or 4 revs per
each rev of the encoder it would still work just fine even for threading.
A non-integer would be a problem though.

I have a lathe with a moderately large spindle. I want to drive an
encoder (well, actually, a resolver) at a 1:1 ratio from this.
The obvious way is with a 1:1 gear set, or a belt, but that does
involve really quite a large gear on the weeny resolver shaft.
I have been thinking about a 200:1 worm

"Thermistor" is the generic name for a device that changes resistance with
temperature. I believe that they are available as both NTC and PTC
(negative/positive temperature coefficient) devices. As noted in my earlier

Having said that, the sequence required for a lathe is rather simpler
than for a milling machine.
The "carousel" HAL component can do a lot of the work:

The easy answer is 'yes'.
The harder and correct answer is 'not until you make it do it'.
Take your right forefinger and thumb and pinch your right earlobe. Hold
