This is the result for the 7i92t unplugged from the 7i77.

~$ mesaflash --addr 10.10.10.10 --device=ETHER --rpo 0x1000
0001FFFF

I tried something different here with the following result.

~$ mesaflash --addr 10.10.10.10 --device=ETHER --rpo 0x1000
000192FF

Hello,

I have an Amazon 4th axis that features a 6:1 reduction drive.

I found the thread here where you adjust the SCALE so that a G0 A360 will turn the axis a proper 360°. 

However, the drive spins too slowly. 

I can double the SCALE, which gives me the speed I want, but then I have to do something like G0 A180 for a full turn.

Is there a way I can speed the drive up, while maintaining proper scale? 

In that case

mesaflash --addr 10.10.10.10 --device=ETHER --rpo 0x1000

should work

(with 7I77 disconnected)

I also bought lm331 to convert current from a dc spindle... I made a small circuit, but I haven't tried it for almost a year because my brother had serious health problems. I'll try in a few days, maybe we can help each other.
regards
Mauro

OK that's curious. How did you get the pinout information if not via mesaflash?

Yes I can ping.
Also linuxcnc works fine except for the missing axis's.

Can you ping the card 7I92T?

After six weeks of doing everything wrong a few times and being graciously corrected by everyone in the community my franken-build Pi 5 debian is working very well.

I'm about to start clean and do everything as has been documented in this thread without my own improvisations which I think got me little except the motivation to learn everything necessary to fix all the things I broke.

I wanted to make sure I'm starting with the latest of Rod's builds and I think it is this from the Google-Driver:

   rpi-5-debian-bookworm-6.6.54-rt39-arm64-ext4-2024-11-06-2037_qtpyvcp_stable_networkmanager.img.xz

The one on the Downloads page is still:

   rpi-5-debian-bookworm-6.1.61-rt15-arm64-ext4-2023-11-17-1520.img.xz

I'm pretty sure I want the one from Nov 2024 instead of Nov 2023.

Is there an even newer one?


 

Maybe you have a old copy of mesaflash
try this

mesaflash --device ethernet --addr [ip_addr] --rpo 0x1000


What IP address is the 7I92t card set for and what does:

ip a

report?

It just says board not found.
