OK. I found that but it did not correct the problem.

// set to false/true for normal / inverse direction
#if DAVINCI==0
#define EXT0_INVERSE false
#endif
#if DAVINCI==1 || DAVINCI==4
#define EXT0_INVERSE false
#endif
#if DAVINCI==2 || DAVINCI==3
#define EXT0_INVERSE true

I have a davinci 1.0 (j37) so I changed

#if DAVINCI==1 || DAVINCI==4
#define EXT0_INVERSE true

It can't move the filament forward.

It's like it moves forward and then immediately backwards.

Thanks for the reply. I guess I thought if that was the case then when I select unload it would try to load. On the davinci can I change the default direction?

You have to edit the E motor direction in the configuration.h tab of the firmware when it is open in Arduino. Then save it and upload it to the printer.

Check the direction the extruder motor is running. The default direction might be reversed for your motor.

I've taken a Davinci 1.0 (J37) to repetier host 0.92.10 and have an issue I can't get by. My extruder worked fine before the flash. Now, if I try to load filament The extruder moves forward , backward, F,B,F,B. The same happens with Unload. I can tell this because when I try to lightly give filament to load, it pushes pulls. Everything else seems to work fine. I can cal the bed. move it around in slic3r and heat the bed/extruder. It reacts the same in slic3r or at the davinvci panel. I don't believe the extruder is clogged or has a miswire.
