[Marlin M218 Extruder Offset.Documented as only X / Y but the code says also Z?]

Anyone get anywhere on this? I wish slic3r had this option, but for now I'm trying firmware implementation. When I comment out the ifs it seems to work (compiles/uploads fine) and when I send M218 T0 Xxxx Yyyy Zzzz (works fine), but when I send M218 T1 Xxxx Yyyy Zzzz (or even just M218 T0 Xxxx Yyyy) it freezes. I'm thinking there are other areas that have if statements that expect dual_x_carriage to be defined, and are therefor not working...

NEVERMIND I GOT IT! You just have to comment out another if here:

// Extruder offsets

#if EXTRUDERS > 1

#ifndef EXTRUDER_OFFSET_X

#define EXTRUDER_OFFSET_X { 0 }

#endif

#ifndef EXTRUDER_OFFSET_Y

#define EXTRUDER_OFFSET_Y { 0 }

#endif

float extruder_offset[][EXTRUDERS] = {

EXTRUDER_OFFSET_X,

EXTRUDER_OFFSET_Y

//#if ENABLED(DUAL_X_CARRIAGE)

, { 0 } // supports offsets in XYZ plane

//#endif

};

#endif

and the original, both in marlin_main:

#if EXTRUDERS > 1

/**

* M218 - set hotend offset (in mm), T X Y

*/

inline void gcode_M218() {

if (setTargetedHotend(218)) return;

if (code_seen('X')) extruder_offset[X_AXIS][target_extruder] = code_value();

if (code_seen('Y')) extruder_offset[Y_AXIS][target_extruder] = code_value();

//#if ENABLED(DUAL_X_CARRIAGE)

if (code_seen('Z')) extruder_offset[Z_AXIS][target_extruder] = code_value();

//#endif

SERIAL_ECHO_START;

SERIAL_ECHOPGM(MSG_HOTEND_OFFSET);

for (int e = 0; e < EXTRUDERS; e++) {

SERIAL_CHAR(' ');

SERIAL_ECHO(extruder_offset[X_AXIS][e]);

SERIAL_CHAR(',');

SERIAL_ECHO(extruder_offset[Y_AXIS][e]);

//#if ENABLED(DUAL_X_CARRIAGE)

SERIAL_CHAR(',');

SERIAL_ECHO(extruder_offset[Z_AXIS][e]);

//#endif

}

SERIAL_EOL;

}

#endif // EXTRUDERS > 1
