Editing the firmware to adjust settings for a new feeder wheel

[PrintingRevo 3]

Dear all,

I have recently discovered a guide which suggests all sorts of modifications to the Ultimaker for enhanced performance. You can find it here: https://github.com/StrawsonDesign/Ultimaker2_Mods/blob/master/Ultimaker%202%20Experiences%20and%20modifications.pdf

One of the best suggestions is to change the feeder wheel in the back of the feeder. The new part leaves a nice gap  for the filament to drop into, but naturally the diameter at that point is smaller. So they suggest to edit the firmware, namely to "change the feeder motor steps/mm" to a value of 327.

I have never done any modifications to the firmware, nor do I know how to manually upload the files to the printer. The explanations in the guide file are inconclusive.

Can anyone point me in the right direction on what I need to do?

In this screenshot you can see the necessary modification:

Best regards
