So I got the SKR mini E3 for my Ender 5 after hearing all the positive reviews.

When it arrives I plug everything in, make sure it's secure and test the axis... they all worked correctly.

I then tested auto home... everything worked.

I then tested the heating... everything worked again.

Finally, I go to do a test print-- it heats up and then homes. When it is finished heating, the hot end assembly starts moving slowly until it goes into the corner and contacts the side of the printer. Obviously, I turned it off right away.

Currently, I am uncertain whether it is a firmware issue, a board issue, or something else? If anyone could please help me solve this, that would be greatly appreciated!

So I found an answer on Reddit when I asked the same question: It actually had to do with the homing -- basically, it was starting at 220, 220 instead of 0,0, which resulted in when the print started for it to head straight into the corner. In order to counter this, I had to change some of the firmware. Everything works now. Thank you for your help!
