X and Y Limit Switch Spacers - JGAurora A-3

thingiverse

These spacers are designed to place the nozzle precisely over the print bed, not floating in mid-air to the bed's front-left side. The x spacer snaps onto the rod and slides into a pocket in the existing bracket on the left. Meanwhile, the y spacer fits snugly onto the rear of the lower bed plate, right next to the limit switch. Ensure that this clip is free from other printer parts as the bed moves through its range. Now when you perform an "Auto Home", the x and y limit switches will contact these spacers and position the print nozzle exactly over the bed at the front-left corner. This eliminates the need to modify G-code for re-zeroing over the bed. Without accurate zeroing, the printer will skew its prints to the left and forward, resulting in several issues: Off-center prints are a common problem. The loss of usable space on the right and rear sections of the bed is significant. There's also a risk of printing in mid-air to the left and front of the bed.
