Ender 3 wrong size bed
I used firmware builder and when I autohome my x axis is too far left and my y axis is too close to me. In addition to this, my z axis moves up a little bit but the bltouch doesn't deploy and my z axis doesn't start to move downwards. What is causing this problem. Is it my bed size in the firmware builder? I'm using an ender 3 and I've tried 220x220 and 235x235 and both had this probelm.
It seems like there's multiple problems here.... First get your BLTouch deploying. Normally this is a cabling problem...
As for centering things, you may need to look at the M851 option in Marlin to fix your probe offset:
