Schaublin 125-CNC retrofit.

Andy started a discussion on the Mesa Card choise in the YT comment section, but I would like to record my thoughts on it here:

I will do a control panel up on the stalk like Schaublin did it. The PC will be housed there. So it will be Cat 6 down to the electrical cabinet to a 7i9x
I have two of Peter's (Talla83) RS422 - SS adapter cards made. These will take to place of a 7i74 next to the 7i9x.
I will need more than 6 Outputs, so I will need a 7i84. I'll also use a 7i73 back up in the user control panel.

I also have some of Peters PCB's to make up two TsHw boards, which I can use as Encoder interface boards with Cat 6 back to the SS adapter cards.

The bit I am stuck on is which 7i9x to get? I am pretty sure it will be an analog servo system, so a 7i97 would work, but that is the biggest and most expensive card, which seems like overkill for two Servos and 3 encoders.

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?

I guess I could do 7i93 / 7i33TA and then run all the SS stuff though the extr 50 expansion slot right?

Do you know if the Stmbl servo drive design has overcome that one IC being not available anymore ? Or if there is continuing effort in the Stmbl servo drive ? Hope there is as I thought it was a very useful - configurable servo drive .

I don't know details from this project, but there is actually work progress....

Thank You ----for the update about your Schaublin lathe , you have been busy .
Relays - pneumatic valves - contactors for motors

Wonder if ZincBoy ( Retrofit of a Hitachi-Seike VK45 mill ) would provide details of his solid-state relay Bd.?


Would a 7i77D or 7i83 be worth considering ? Trying to attach a YouTube thing about lost foam casting that shows a cheap vacuum accessory .

Unfortunately we don't have any low channel count analog 25 pin daughtercards

Probably the best would be a 7I94+ 7I77 combination

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.)

How about the 7i83?
