  1. This is the gcode I've pieced together from various sources & got working. I have to set up each extruder as a separate printer. So I can use the left or the right but no dual extrusion. With the X3GWriter plugin by Ghostkeeper cura will output x3g. Right Extruder Start Gcode ; begin M136 ; tell the firmware we're starting a build M73 P0 ; reset build progress G130 X118 Y118 A118 B118 ; set vref's to default M190 S{print_bed_temperature} ; set bed temp, don't wait M104 S{print_temperature} T0 ; set right nozzle temp, don't waitdisable right nozzle, don't wait M104 S0 T1 ; disable left nozzle, don't wait T0 ; home on the right extruder G90 ; set positioning to absolute G28 X Y Z ; home XYZ at default home feedrates G92 X0 Y0 Z0 A0 B0 ; define this as Z=0, the other coords are technically unnecessary but x3g requires them so gpx will make some up G1 Z5 ; move the platform 5mm down G28 Z F500 ; so we can home z again slowly M132 X Y Z ; Recall stored home offsets G1 X-95 Y-73 Z30 F7000; move to waiting position (front left corner of print bed) M116 ; wait for target temperatures to be reached. GPX only, RepG doesn't understand G92 E0 ; set current extruder position as 0 so that E15 below makes sense G1 Z{first_layer_height} F6000.000; move to first layer height G1 X100 Y-73 F7000.000; move to front right corner of bed G1 X-90 Y-73 E24 F2000.000; extrude a line of filament across the front edge of the bed G4 P2000; wait for ooze to slow G1 Z0 F6000.000; lower nozzle height to 0 G1 X-95; wipe nozzle G1 Z{first_layer_height} F6000.000; set nozzle to first layer height G1 F7000; ensure fast travel to first print move G92 E0 ; set E to 0 again because the slicer's next extrusion is relative to this 0 ;end Left Extruder Start Gcode ; begin M136 ; tell the firmware we're starting a build M73 P0 ; reset build progress G130 X118 Y118 A118 B118 ; set vref's to default M190 S{print_bed_temperature} ; set bed temp, don't wait M104 S0 T0 ; disable right nozzle, don't wait M104 S{print_temperature} T1 ; set left nozzle temp, don't wait T1 ; home on the left extruder G90 ; set positioning to absolute G28 X Y Z ; home XYZ at default home feedrates G92 X0 Y0 Z0 A0 B0 ; define this as Z=0, the other coords are technically unnecessary but x3g requires them so gpx will make some up G1 Z5 ; move the platform 5mm down G28 Z F500 ; so we can home z again slowly M132 X Y Z ; Recall stored home offsets G1 X-95 Y-73 Z30 F7000; move to waiting position (front left corner of print bed) T1 ; select left extruder M116 ; wait for target temperatures to be reached.
