@Phaedrux said in Error: G0/G1: insufficient axes homed:

Keep in mind that your movement directions should be like this
-X to the left, +X to the right
-Y to the front, +Y to the back

The endstop position is arbitrary, so rear right is fine. But are your motor directions correct?

To have the endstops at the rear right and the low end of travel means that your axis movement would need to have

-X moving to the right, +X to the left
-Y to the back, +Y to the left

Your homing files would need to flip their directions from what you have now so that they move towards the endstop.

You may need to change the direction of rotation of the motor to achieve this.

And keep in mind this would have the effect of your prints being rotated 180 degrees from the slicer preview.
