RAMPS 1.3 E1 pinouts?

It appears that my Z motor controller connector has failed (z motor works when connected to a different axis - z pololu works when moved to a different axis), so I'm trying to move Z over to the E1 connector.

My problem is, I can't figure out what the pins for E1 are.

I'm looking for pin definitions for sprinter/tonokip, rather than for teacup, assuming there's a difference.


#define E1_STEP_PIN ?
#define E1_DIR_PIN ?
#define E1_ENABLE_PIN ?

They are over on the Daal Row connector, the row closest to the inside of the board. Look for the Step and Dir pins on E1, and trace them on the back of the RAMPS to the edge connector. They are 10 and 11 counting up from the bottom. Don't know the actual numbers for these. Sorry.

Well, for the next person who needs to know this:

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

This is now in the Sprinter pins.h

i have same issue on Y and need to move it to E1 - but what is the same pin for Y_MIN if using E1?
Does that pin even really matter?

Y_MIN is probably the endstop, which isn't on the driver connector, so doesn't need to be changed.
