Hello,

It seems the current settings weren't being saved. I redid the config and it's working now.

Thank You

I have a duet wifi running a syringe pump setup using two geared extruders. Today when setting up for a print I found that while the extruder steppers would respond to a direct command to extrude they weren't doing so during a print. Simultaneously I found that the extruders had very little torque when turning compared to previously. I also have intermittent warnings about poles a and b being disconnected for the driver I'm attempting to use to extrude.
Several people work with the printer so I checked the config. Motors we're set to reasonable current values. I'm running the most recent firmware. I checked connections and wires and swapped motors to no effect. I swapped the extruders on to the y axis stepper and they worked normally with sufficient torque.
I'm not quite sure what's going on or what to check next.

Thanks
