How to correct XY mirroring? So I made a 3D printer from scratch. It is a RepStrap based on a Prusa i3 running Marlin 2.0.x.
It prints fine and accurate, but, The trouble is that the XY plane is mirrored and I don't know how to solve this.
I'm using Marlin 2.0.x on an SKR 1.4 controller board.
Any pointers would be greatly appreciated.
Thanks!
First of all, make sure that you have correctly identified the X and Y axes, and that the stepper motors (and end-stop switches) are connected to the correct ports. The hot end moves on the X-axis, and the bed moves on the Y-axis. If you connect the X and Y motors the wrong way round, you will get reversed text.
If the X and Y motors are connected to the correct ports, you may need to invert the motor directions in firmware. There are #define statements to allow you to do this.
