I have had my machine for a few months now and have got my machine calibration as best as I can using custom slicer profiles but I have questions about other techniques. I have seen online where people are editing the steps per mm and other values for movement of the extruder gantry and the actual distance extruded. I was wondering if this can/should be done on the Replicator 2X or if it is not necessary. Also where other calibration methods can/should I try?
