i have built a 3d printer . and the problem coming is that it is printing the mirror image of my .stl file. the right side of the printed part becomes left and left becomes right one . is there any solution to this problem.
Move endstop and change motor direction on one axis.
You can change the firmware INVERT_X_AXIS if your using Marlin or you can turn the plug around on the X axis motor.
