Y axis moves 4 times too far then X axis!!?? 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? Regard Ola A.

One of your micro stepping jumpers (under the Y stepper driver) is missing or just not working.. Check all 3 jumpers exist and that there is a bit of metal in the jumper.

Finally. Now everything works as it should. Some of the jumpers probably had a bad connection. Thank you for your attention and commitment.
