in everybody configuration.h stays this code :

#define DEFAULT_AXIS_STEPS_PER_UNIT   {78.7402,78.7402,200*8/3,760*1.1}  // default steps per unit for ultimaker

This last Number  760*1.1 gives 836 steps per E


I think that beside this code it should be comment that is missing everybody:


760*1.1 is for new bolt - think it is v3 version


......but many of us that have v2 bolt and made hot bed this is not working good- it shold be 865


I think that this must be commented in code, because many that must compile new FW for HOTBED will run in problem of extruding to small amount of filament.....

It doesn't matter if you use cura as this is ignored.  In all gcode files generated with cura it says (second line of file):


M92 E836.000000

This M92 E___ command sets the steps/mm.  This line is in EVERY gcode file cura creates.  To set this value, in cura, go to "file" "preferences".
