I am running a duet 2 wifi and hemera dd kit on my ender 3 pro everything works but when you tell the hemera to extrude it retracts and when told to retract it extruded I've tried to turn the plug the opposite way on the duet but I get short errors and it makes a lot of noise the other way so right now it dr runs fine no noises but its reversing the commands. Here a image of it plugged into the duet
Yep. You can. Here's an example extruder definition... M569 P3 S0 To flip the direction you would simply change this to: M569 P3 S1 Duet docs for M569
