This code should be at the beginning of every Gcode file:
M757 S[nozzle_diameter] ;set layer/path width M729 S3 ;set 16 step mode M758 S0.095 ;set steps/nL M734 F60 ;set error reporting interval for redundant errors to every 60 seconds ;--------------------

Layer Changes
Please also note, that if you want to take advantage of several new features regarding layer change options, ( I.E. pause at end of layer, take picture, etc) you will want to add the M790 to the layer change G-Code as well:
M790 ;announce new layer
Everything
Here is code that should be in EVERY recipe:
;now we set up for any build offsets that we may want G21 ; use millimeters G90 ; absolute coordinates G0 Z5 ; lift head to avoid collisions G28 X0 Y0 ;always home before starting a build home X and Y G0 X0 Y0 ; move to desired origin, necessary if you want a negative offset G92 X0 Y0 ; reset origin:to new X and Y, it is legal to add values to x an y, I.e. X30 Y40 will ;set the current location to X30 an Y40 M83 ; relative extruder coordinates ;set up Head Flow characteristics M6 T10 ; select all heads on yoke 1 ;M227 ; enable unprime/prime on non printing moves M221 S1.0 ; set fudge factor for extruder to 1.0 M756 S[first_layer_height] ; set first layer thickness M757 S[nozzle_diameter] ; set layer/path width M729 S3 ; set 16 step mode ;set the pulses per unit volume, this is different depending on extruder type ;and material size, I.e if the 1.75mm filament is really 1.65, you can adjust this number ;Or the Fudge factor M221 to get the correct amount of material. M758 S0.095 ; set steps/nL
Typical S values for M758:
MK-1 ABS 1.75mm .09-.12 EMO-25 Plasticine .06
