Topic: Extruder will not load filament after repetier firmware install

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.

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

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.

Re: Extruder will not load filament after repetier firmware install

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.
