50-pin + smart-serial can work well if you have a PCI PCI-e slot. The 5i24 / 6i24 are a lot of pins for the money, and are what run my lathe.
(My lathe is 6i24 7i49 7i44 7i84 7i73 2x8i20 and has a whole 50-pin connector free.)

The 7i98 or 7i94 would be cool, but I don't see a DB25 daughter card which supports servos. The 7i33 needs a 50pin FPGA Card right?

How about the 7i83?

Unfortunately we don't have any low channel count analog 25 pin daughtercards
Probably the best would be a 7I94+ 7I77 combination
How about the 7i83?

Mark Are you considering future servo driven Live Tooling on the extra turret , that all us viewers are going to want ?

Wonder how I missed the 7i83?

You still need the encoder inputs
One possibility is a 7I92+ 7I85 +7I83

Why the 7i92, if only using SS daughter cards, the 7i94 would be a better fit wouldn't it, or is there no LinuxCNC HM2 driver support for it?
7i94 - Brain
7i83 - Analog motors
7i84 - IO
7i85 - Encoders
7i73 - Control module.
That set pretty much duplicates while a liitle cheaper than 7i97/7i74/7i73/7i84 with a smaller footprint, if I can make up something to stack the 7i94, 7i83/7i84/i85 vertically if the space gets too tight.

Bob, did you watch his follow on video with the motor cooling fins? Excellent.

The 7I85 already has 5 sserial channels so a 7I92 is a bit cheaper

Thanks, save €65 verse butcher 4 Cat 6 cables, pretty good deal, thanks.
Just wondering, by why not just put RJ45 sockets on all the boards which have RS-422 ports? They'd be cheaper than the plug in screw connections, easier to to fab, and easier for the user to integrate.

Yes , I watched many of his casting videos some of which show details about his electric melting furnace construction . ( electric heating coil type furnaces tend to burn out quickly at cast iron temperatures )
Anyway, his video included a section of his vacuum pump which I thought might be interesting to you . As I was watching his Lost Foam technique wondered if 3D printing a female mould an then fill it with foam in a can insulation stuff could work for making lost foam patterns .
Break time is over - back to the Schaublin 125-CNC retrofit.
