Stepper Motor Starts But Doesn't Turn was created by Joliet
I'm using LinuxCNC 2.9.1 on a Raspberry Pi 400 with Debian 12 "Bookworm" (just for benchmarking, will upgrade to desktop when I get everything installed on a real machine) and connected to a Mesa 7i96s.
The 7i96 is connected to a DM542t, which is then connected to a Nema 23 stepper motor ( www.oyostepper.com/goods-1198-Nema-23-St...Wires-8mm-Shaft.html ) that is set up for the X axis. I installed everything and ran the Mesa config tool and it shows a connection to the 7i96s.
When I turned everything on I was driving the stepper motor and knew this because it was frozen and I couldn't turn it.
The connection between the 7i96s and the driver is as follows:
Step 0--->Drag-
Step 0+ -> Pool+
Directory-->Directory-
Catalog+ -> Catalog+
I don't know where to start troubleshooting, any information would be helpful.
Thanks.

Probably something wrong with translation as the naming is way off, there are no drag, pool, directory (there is dir or direction), catalog!
The first thing to check is if the card is communicating with the PC:
ip a
ping 10.10.10.10 or 192.168.1.121
Depending on what the Mesa board is set to, see manual.
If all that is OK, then set the timings in the ini file or use the wizard, to 5000 for both step time and step space, and 20000 for both dir values.
