Need some help setting the Z-endstop

Post by daveb » Tue Aug 15, 2017 9:30 pm

Can anyone help me out with my Z-Stop? I have a M2D that was upgraded with Dual extruders, 4 point leveling and endstop to the bottom. It' has the silver and black motor.Now I'm finally trying to reset everything so I can start printing again. The Z direction moves correctly when using Jog controls. When I try to home the Z axis it sounds like it's trying to drive the plate through the bottom. I'm using a firmware from Makergear. Want to correct this without bugging those guys again. I have tried swapping the direction of the endstop connection to every possible direction with no change.

Does this line in my firmware make a difference?:

// ENDSTOP SETTINGS:
// Sets direction of endstops when homing; 1=MAX, -1=MIN
#define X_HOME_DIR -1
#define Y_HOME_DIR -1
#define Z_HOME_DIR 1

If you upgraded an older machine, the spider doesn't hit the endstop before the nuts on the leadscrew nut hit the motor body.

Bend the lever upwards on the endstop.

Like on FB, you pointed me in the right direction. When I upgraded I made a change in the wiring harness adding RC connectors to some items. Yea the Zstop was one, and I had disconnected the Zstop one inside my wire loom. Thanks a bunch for he reply.
