Z Axis MATH &"E" Axis ? (2 replies)

Hi, I'm using Repetier as my host application & am so close to finally calibrating my Prusa i3... but for some reason the Z-axis is not stepping far enough each turn .. So I think I need to increase the z-axis steps. yes ?

I've looked over the Prusa calculator... but I'm not sure exactly how to add this to Marlin''s Configuration.h file

Here's the area within the file that I believe the math should be changed yes ??


#define DEFAULT_AXIS_STEPS_PER_UNIT {78.7402,78.7402,200.0*8/3,760*1.1} // default steps per unit for ultimaker


So my question is.... do I change the DEFAULT AXIS STEPS PER UNIT ??? & if so whaich number corresponds to the z-axis ? I think it could be 200.0*8/3 ...... if so, is it safe enough to simply double the "200.00" ?

p.s - what is the E-axis..... I'm guessing its the filament feed rate yes ?
