The Calc. E Line Editor

Using The Line Editor Use Calc. E to calculate the Extruder value for your 3D print.   To use the Default values you can just enter the line number you want to calculate.   The Default values are based on a standard personal 3D printer, but the values can be modified for you model or for changes during the printing process, like layer height.   If you leave the "Start E value:" to nil, the calculated Extruder value will be a line specific (relative) value that automatically fills the E field.   But if you want an absolute (continuous) value, enter a 0 or greater value into the "Start E value:" field.   After that, following E values will be added to the previously calculated value and automatically entered into the E field and "Start E value:" field.
