Hi all

I'm upgrading my prusa mendel i3 from a single direct feed extruder to dual bowden extruders.

But two of the stepper motors i have has different gear ratios.

In marlin, what can I do to calibrate the steps/unit for the two motors?

thanks all

The last time I looked into this it was not possible. Repetier firmware does allow you to use different steps/mm. Also you could use M and G codes in your nozzle change field of the slicing software to change the steps per mm of Marlin at each tool change.
