Calibrating the Extruder

In the motherboard firmware, configuration.h file (if there is .dist extension on it copy and paste into the same folder named configuration.h) you have a value that you will need to change in order to have your RepRap/RepStrap working correctly.

E_STEPS_PER_MM

This is set to 0.706 which is the 5mm splined shaft with no gearbox, if this is what your using, change nothing. However if this is not the case you will need to make some measurements and jot them down.

Filament Diameter Nozzle Diameter Pinch Wheel Diameter Steps of stepper

Adrian B. used the formula


<math>\frac{1}{\frac{\pi\varnothing_{pw}}{Steps_{360}}.Ratio_{Nozzle to Filament}}</math>
