Hi, I can´t get my mesa card to work right. (It did before.)

The Problem is that only one axis works at a time.

I,m using LinuxCNC 2.9.6 with QtPlasmaC.
Mesa is connected to DM542T drivers.

I swapped the plugs on the mesa to make sure the hardware works correctly.
Tried different stepgen configurations which made different outputs work, but only one at a time.
Looked at the hal pins, which seem good.

I´m out of ideas and hoping for yours.
Thanks

That sound's more like a wiring or hal file issue than hardware issue with the 7I96S

You might check than the DIR signals for all axis change when jogging each axis in different directions
