Guys, I’m struggling with homing laser. X and Y both have min endstops installed (no max). Click home is laserweb, Repetier, Ponterface, etc, and X moves to the endstop while Y moves away from it. I can’t seem to figure out what seems like it would be so simple…
Here is a snippet of my config for the beta:
beta_min_endstop 1.26^ # Pin to read min endstop, add a ! to invert if endstop is NO connected to ground
#beta_max_endstop 1.27^ # Pin to read max endstop, uncomment this and comment the above if using max endstops
beta_homing_direction home_to_min # Or set to home_to_max and set alpha_max and uncomment the alpha_max_endstop
beta_min 0 # This gets loaded as the current position after homing when home_to_min is set
beta_max 200 # This gets loaded as the current position after homing when home_to_max is set

Maybe I’m not looking in the right location? Any help is appreciated!!

Consider whether you need to invert the beta_dir_pin output, this is actually what controls the direction of the Y axis motor.

Yep, you probably need to invert the direction of your Y axis. Or if the direction is correct, it means your endstop is actually at max, not min.

I will try both of those suggestions. Thanks guys.

You need to find which it is, and do only one of the two. You mustn’t do both.

Well at the moment I’m guessing (hate to say that) but I’ve been digging a pretty deep hole with this laser project. Sad part is, this and a pwm to fire my laser is what’s holding me back right now and I can’t believe I’ve gotten as far as I have lol.

also if you are using the firmware-cnc then homing is NOT G28 it is $H. so clicking home in a 3d based host like pronterface will park heads not home them.
