Hey!
I am a beginner of this. I have uploaded Marlin 1.1.6 to Geeetech 2560 rev. A in my Prusa i3 clone.
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?
