If you have to re-calibrate your X-Axis, you can just use this guide here. But be careful not to crash the hotend into the bed, this might cause the printer to break.
1) M92 to show current steps; write the current steps down as a fallback option!
2) M502 to delete EEPROM
3) M92 Z285.60 to set the Z-Value zo 285.6
4) M500 to save the values
5) M501 to activate the values
6) M503 to check the values again
7) G28 Y to home the Y-axis
8) Manually move the X-axis down, near the belt
9) Now manually move the nozzle down on the belt and test it with a piece of paper. It should scratch a little bit on the nozzle.
10) Check it on both edges of the bed and use the screws to set it to the proper height.
11) M114 to get the new Y-value
12) M206 Yxxx to set the Y-value to the Value from Step 11
13) M500 to save the Values
14) M501 to activate the Values
7) G28 Y to Home the Y-axis
16) G0 Y0 to check the offset. The hotend should stop right before the bed. Watch out that the hotend won't crash!
