Help: Beginner question Homing Direction and end stops Hello! I'm finishing a Prusa MK2 clone. My end stops are (Normally open): X = Left side Y = Rear Z = Inductive sensor In Pronterface, if I hit X home, it correctly goes to the left and hits the end switch. But if I hit the Y axis HOME it goes forward. So: X+ goes to the right Y+ goes to the back Z+ goes up Any thought.

Y+ should move the bed forward

As mentioned above find "#define INVERT_Y_DIR" if its set to true make it false or if its is set to false set it to true.]]> Dust Prusa i3 and variants Tue, 31 Oct 2017 22:21:47 -0400 https://reprap.org/forum/read.php?406,794529,794558#msg-794558 Re: Help: Beginner question Homing Direction and end stops https://reprap.org/forum/read.php?406,794529,794558#msg-794558
So I you don't want to reverse the wire in the Cable only one choice.

// Invert the stepper direction. Change (or reverse the motor connector) if an axis goes the wrong way.
#define INVERT_X_DIR false
#define INVERT_Y_DIR true // reverse the direction here.
#define INVERT_Z_DIR false]]> Roberts_Clif Prusa i3 and variants Tue, 31 Oct 2017 20:21:39 -0400 https://reprap.org/forum/read.php?406,794529,794551#msg-794551 Re: Help: Beginner question Homing Direction and end stops https://reprap.org/forum/read.php?406,794529,794551#msg-794551
/ Direction of endstops when homing; 1=MAX, -1=MIN
// :[-1,1]
#define X_HOME_DIR -1
#define Y_HOME_DIR -1
#define Z_HOME_DIR -1

When you hit Y+ it should go back? Correct? I don't want to switch the motor cable if that is okay.]]> disneytoy Prusa i3 and variants Tue, 31 Oct 2017 18:42:25 -0400 https://reprap.org/forum/read.php?406,794529,794546#msg-794546 Re: Help: Beginner question Homing Direction and end stops https://reprap.org/forum/read.php?406,794529,794546#msg-794546 // Direction of endstops when homing; 1=MAX, -1=MIN

I'm finishing a Prusa MK2 clone.

My end stops are (Normally open):

X = Left side
Y = Rear
Z = Inductive sensor

In Pronterface, if I hit X home, it correctly goes to the left and hits the end switch. But if I hit the Y axis HOME it goes forward.

So: X+ goes to the right
Y+ goes to the back
Z+ goes up

Any thought.

Thanks
