Mostest Minimalistic-est Z-Probe

thingiverse

This three-axis homing code is based on Gav's Z-Probe, with the z-probe mounted outside the build area and not requiring far axis movement. Instead of using glue and acrylic, a smaller board-mount microswitch is used with perf board and standoffs. Home all axes without X/Y endstops (recommended for proper functioning). The homing sequence involves raising the Z stage, moving the Y axis to the rear, then the X axis to the farthest right, lowering Z until hitting the limit switch, setting the current point as Z-origin, raising Z above screws, moving the build platform to the table's center, touching the table, and finally setting the current point as origin. Switch back to absolute positioning for accurate operations.
