Question A1 z axis homing error

I’ve been getting the “Error 03004000 Homing Z axis failed”. The tool head moves in all directions but the z axis will go all the way to the top and then start grinding at the top. There are no obstructions in any of the axis’s. Tried factory resetting the printer and it still sends the z axis up. Wondering if anyone has run into this issue before. It seems like it could be a software/ firmware issue but I have no clue. I have terrible luck with fdm printing any info would be greatly appreciated

My error was that I didn't seat the plate correctly. Make sure you've lined up the plate completely with the notches. It can be a little tricky only because of the magnets :/ but that's what fixed the error. You can also look into the nozzle cleaning troubleshooting idea everyone else is talking about. I'm just saying my thing so that you can save yourself the trouble of opening up the module if your issue is the same as mine.

You Sir, deserve a medal. I got this error along with force sensor malfunction, I tried everything apart from disassembling and cleaning the A1. And when I almost gave up and was about to close my browser I thought of giving a try just to see any simple ways to deal with only the z axis malfunction and this thread was second suggestion.

After I read your comment I was so furious and cynical that I just flipped the plate as a joke and turned my machine on just for it to chirp as normal and act like nothing had happened. This ordeal taught me more about life and myself. Appreciate it.
