Re: Newbie Help Needed - Change Stepper Driver

Just edit your pins.h

In more detail.

In configuration.h you set motherboard = 33
Find that in pins.h starts at [github.com]
The extruder pins are defined [github.com]

so take

#define E0_STEP_PIN 26
#define E0_DIR_PIN 28
#define E0_ENABLE_PIN 24

#define E1_STEP_PIN 36
#define E1_DIR_PIN 34
#define E1_ENABLE_PIN 30

and make it

#define E0_STEP_PIN 36
#define E0_DIR_PIN 34
#define E0_ENABLE_PIN 30

#define E1_STEP_PIN 26
#define E1_DIR_PIN 28
#define E1_ENABLE_PIN 24

Save, compile and upload.

Now E1 and E0 are swapped over.
