First post here, and first time working with LinuxCNC. Got a 3-axis gantry system with working stepper motors I'm looking to convert to LinuxCNC. For some reason, I can't get the steppers to move. Have a Mesa 7I92TF connected to a 7I76. Currently only have a single stepper driver (Gecko GR214V) connected to the 7I76. Self-test on the gecko drive moves the stepper as intended. When I'm in PNCConf trying to tune the axis, I can't get the stepper to move at all. I've tried adjusting the stepper info with no success. Any ideas what I'm missing? Is there a good way to verify that the 7I92 and 7I76 are communicating? I've attached pictures of the wiring if that's helpful.

This is normally related to the stepper drive enable signal. The PnCConf axis test might not know how to enable drives. (I remember that this used to be the case, but don't know if it has changed)
Most stepper drives default to enabled, so just disconnecting the wires to the enable inputs temporarily might fix this.

Do you have 7I76 firmware installed in the 7I92T?
(should be 7i92t_7i76x2d.bin)

My driver is enabled by default so I don't currently have any connections to the enable pin.

No, is there a software I need to compile that or was there a download I missed somewhere? Thanks for the help, I definitely underestimated the learning curve

Download the 7I92T support software:

www.mesanet.com/software/parallel/7i92t.zip

Unzip the archive

cd to configs/hostmot2/

and then run the command:

mesaflash --device 7i92t --addr 10.10.10.10 --write 7i92t_7i76x2d.bin --reload

( assuming your card IP address is set for  10.10.10.10 )

Downloaded and unzipped the files, but when I go to run the command, I get an error that says "Checking file ...Invalid bitfile header!" I only see .pin and .bin files in the folder. Should there be a .bit as well?

You need a recent mesaflash for the 7I92t[x]:

github.com/LinuxCNC/mesaflash

( build/install instructions on bottom of page )
