Considering a Full Rewire on a Working Schaublin 125 CNC

Do you have field power connected to both 7i84's?
I would forget PNCConf for now. If you have the 7i92 communicating with LinuxCNC, then open the HAL show, and see if you have all the pins available on the various cards.

One of the 7i84 cards is detected and shows all pins, with both field power (power over the RJ45) and power over the VIN pin present (not at the same time, obviously), but it gives a low-voltage error and does not seem to actually work. The second one I cannot get to be detected at all.

I really need multiple Smart Serial cards to be detected for the system to work, and on the 7i92/7i85 I can only get Smart Serial channel 4 to detect anything.

I will not be in the shop today, i will provide pictures of the wiering tomorrow.

Our set up with 5 Mesa cards is a pretty unusual one, so it might be beyond the scope of PNCConf to configure it. I only used PNCconf to get the basic frame work set up, and then did all the rest by manual editing the HAL, or in my case a bunch of hal files, as I found it easier to break the HAL into single topic files, and work through them one at a time.

Try the HAL's I sent you? Since we have the same cards, LinuxCNC may start with them (although it is more likely it faults out due to cards connected in a different order than mine. For some reason my second 7i84 mounts as 7i84.0.3, rather than 0.1 for example.

I did not see any files from you. But at this point, I am relatively certain that something is wrong with the 7i85 I am using. I had planned to just get the basic config running and then do the rest manually, but since I cannot get to a point where all cards are shown in HAL Show, I am a bit at a dead end.

I am seriously considering getting a 7i97T, as I have spent a week on this now and don’t really see where to go from here.

One way to maybe get this running would be to connect a 7i74 to the P1 connector of the 7i92, but there is no firmware available for that combination (7i92T + 7i74 on P1 + 7i85 on P2), and I am not nearly knowledgeable enough to create it myself.

I thought I emailed them to you last week. I'll check tonight.

Don’t worry, I don’t know how often I intended to attach something and then just didn’t. I asked when I was still having problems with the PnCconf setup, so it is not relevant anymore. But thanks.

Try a HAL with just this header in it... this works on my set of Mesa cards. You will probably need to change the IP address.
