6i25 (5i25) + 7i85s + 7i85s PNCconf problems and questions

Hi,

I made a schematic of my connection. I am kind of scared to blow up the 7i85s or the 6i25.

Would this be a correct setup to start for one axis if in pncconf. as I/O connection 2 selected stepgen X axis on the 3rd dropdownbox?

Hope someone can review and let me know. Thx.

Do you have the 6i25 jumpers W7 & W8 set, as mention in the manual, for use with 5i25 bit files, if you are using 5i25 bit files ? (that's if this information is applicable)

Is the 6i25 jumpers set to supply power to the 7i85s ?

Hi ozzyrob,

I have left all at default... (As they were on delivery) as I think those are the correct settings. The 5i25 is loaded with firmware 5i25_7i85sx2 the frequency is 33 . And mesaflash worked to flash as 5i25.

So I haven't touched the jumpers yet.

I'd be inclined to read the manual to make sure how the board is setup matches the way you want to use it. Always pays to check.

Also that seems like a confusing axis connection

Why would you not assign stepgens in the natural order:

X = Stepgen 0 = TX0,TX1
Y = Stepgen 1 = TX2,TX3
Z = Stepgen 2 = TX4,TX5

That's a good question. Because the first drop-down menu I choose X than Y than Z and that leads to Tx6 and 7. But I will change that. Makes more sense indeed.

How about my schematic for connecting the driver is that looking ok?
