I don't know
One of the problems with the PMDX-126 BoB is that although it takes two
parallel port connections the second port only brings the inputs out to opto
isolated terminals on the edge of the BoB.
The outputs (or alternatively inputs) are not brought out. Instead they go to
a proprietary

I keep forgetting the circle can be drawn by a helical xy path, dropping
z at the right pitch. Great idea Stuart, just haven't tried it yet.

The 7i96 would work well, but it does not have a significant amount of IO
pins, or analog outputs for spindle control.
If you intend to control the spindle via LinuxCNC and plan on adding more
peripheral devices, the 7i76e might be a better choice. Expansion boards to
add more IO and spindle
You don't need a boring head. An end mill adapter/holder will work just
fine.

I am thinking about changing my Gatton CNC over from a parallel port
and BOB to a usb or ethernet setup. The current setup works but from
what I have read I will have smoother control with one of the Mesa
boards.
I think that the board that would do this is a Mesa 7I96. It is

I know many people who would be able to use it like Jeremie does, with a
separate program tied to each WCS.
On a related note, Tormach's videos for their newly released 1100MX say
that they will be expanding the number of WCS to 500 with a new version of
PathPilot.
I am curious as to how much

Gene,
I frequently use a boring bar with a threading insert to thread mill
threads. It is a one flute thread mill but it does a wonderful job and is
not expensive. You can cut OD and ID threads.
Works a treat.
If your mill doesn't have a spiral code then maybe your CAM package can
output the

Hi,
Silent lurker stepping in on this one
On the Sinumerik 840d I work on, I have G54..G59, plus G500..G599 !
As I'm planning a modular clamping table plate with many indexed subplates,
those many WCS will be very helpful for each plate to have its own.

I think that the output of a 7i76 is actually a digital potentiometer, with
no PWM stage involved. It's part of the smart-serial subsystem.

I haven't checked. I never need zero rpm out of my VFD except when it is
off, and that's a separate set of on/off terminals.

I mainly selected it for the output driver, which actively discharges the
cap through the resistor when off and charges when on.
