Hi, everyone ... hoping someone can help:

My Orca V.03 is all built, cabled up, powered up. X, Y, and Z all seem to move in the right directions (after quite a lot of fiddling about).

I am using "ErikZalm-Marlin-0-9-3_Orca_030_new_opto-4G-acc firmware"
Arduino 0018, Sanguino 0018 (Sanguino-0018r2_1_4)

I am on Windows XP (quaint old fashioned thing that I am ... it's a very old laptop!)
Using Pronterface.

I have compiled the firmware, with these settings:

//// 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

-------------------
These settings are changed from those shipped with Marlin, which were:

#define X_HOME_DIR -1
#define Y_HOME_DIR -1
#define Z_HOME_DIR -1

(until I changed those, the optos only worked if the carriage was moving away from them)

-------------------------------------------------

X+ moves right (away from opto)
X- moves left (towards opto, and stops at the opto)

Y+ moves backwards (towards opto, and stops at opto)
Y- moves to the front

Z+ moves down
Z- moves up, towards opto, and stops when it gets there.

The extruder motor runs in the right directions

The hot end heats up and reaches target temperature.

BUT. "HOME" doesn't seem to do anything, nor does HOME X, HOME Y or HOME Z.

And ... if I manually home the machine (move all axes to the optos) and start a print, the first thing it does is very slowly move away from that position before starting to print (this is a dry print: no filament).

What am I doing wrong? I am being driven nuts, and Camiel isn't reply (again! Even to ME!)

So if anyone can help, I'd be really grateful.

Once you have manually homed the axes try pressing reset on the Gen6. Then try the print. The GEN6 uses the position the axes are in at power on as its default home.
