Hey, sorry, I'm at a complete loss here, and can not seem to figure it out.
I have 90% of the machine built... (ITS AWESOME!!) Thanks Chris!
I just can not get my head wrapped around the firmware settings for homing the Z axis.
X and Y are working properly.
Z will operate correctly, only when homing in the down direction. When I define Z_HOME_DIR from -1 to 1, the switch becomes inoperable.
When sending a M119 I get: x_min:L x_max:H y_min:L y_max:H z_min:L z_max:H
which I believe to be correct?
When I home in Prontrface with HOME_DIR set to -1, the sequence in homing is X, Y, Z.
When I home with HOME DIR set to 1, the sequence is Z, X, Y. ??
What am I missing?! LOL
