PMDX-424 vs PMDX-416

[Rubes]

Currently investigating going the Mach4 route with a new build (still working on a LinuxCNC with Mesa cards as well).
Is the 424 that much more popular than the 416 just because of the isolated USB and 4 additional inputs?

Also, when I see things like "in the future" or "coming soon" (in reference to threading with these two boards) in product descriptions I get a bit worried. there have been way too many products and software that have left many in the dust with open ended promises.
Since this is for a lathe application, that is an important detail.

Anyway, still in the early stages, and wanted to know what I give up, if anything, with the 416 vs the 424.

The isolated USB is the major factor in people choosing the PMDX-424. The
other major differences are the extra inputs and running from mains power
instead of being USB powered. More details here:

You have a valid point about the "coming soon" dilemma, but we have a
Christmas present for you. We expect to release the new plug-in that
supports lathe threading this week. We have had running code for a
while, but were waiting for reports back from beta users. We finally got
one from someone testing with an actual quadrature encoder and are
now preparing the release notes and installer for the new plug-in.

Thanx Steve.
Reading my post again and I sounded like quite a jerk on the "coming soon" thing...didn't mean it that way, sorry!!
I certainly appreciate someone who tests more before releasing, than sending it out and let the world debug for them.

Thanx again
Merry Christmas

We made it. As of today, 22 December 2106, the new SmartBOB plug-in
with lathe threading support has been released.
