Hey!
I am a beginner of this.
I have uploaded Marlin 1.1.6 to Geeetech 2560 rev. A Geeetech Prusa i3. In Configuration h. I have 7 as motherboard.
Has set DEFAULT_AXIS_STEPS_PER_UNIT {78.74,78.74,2399,102.5} Everything works except that the Y axis moves 4 times too far. The X-axis is perfect. As I see it, X have the same physical conditions as Y.
What do I miss?

Y axis moves 4 times too far then X axis!!??
Re: Y axis moves 4 times too far then X axis!!??
Which model is your printer? The x and Y steps/mm is same. And it is impossible that the Y moves 4 times.
