That's the weird thing... I haven't touched netfabb yet. I've just been testing w/ skeinforge 35 and 40 right from within RepG.
The default Configuration.h in the Marlin 1.0B1 has the following defined for the steps per unit:
#define DEFAULT_AXIS_STEPS_PER_UNIT {78.7402,78.7402,200*8/3,760*1.1}
Does that 760*1.1 look correct? (That is the one for the extruder stepper, right?)
BTW: Even though I just recently got a chance to build my Ultimaker it originally shipped out on 18.08.2011 - Is it possible that I have some older components in my build that may need accounting for in the newer firmware?
Thanks!
