Endstop Y-axis for Prusa i3

thingiverse

For Prusa i3 enthusiasts, calibrating the Y-axis endstop is a crucial step to ensure seamless printing performance. Begin by locating the Y-endstop switch, usually situated at the bottom of the printer's frame near the X-carriage. This switch is responsible for signaling the printer when it reaches the minimum point on the Y-axis. To set up the Y-axis endstop, start by loosening the screws holding the endstop switch in place. Next, adjust the switch to sit snugly against a fixed point on the Y-rail, usually a metal bar or a printed component specifically designed for this purpose. Once adjusted, tighten the screws firmly to secure the switch. Now, it's time to calibrate the endstop itself. With the printer powered off and the X-carriage in its home position, carefully insert the endstop probe into the Y-endstop hole on the carriage. Make sure it clicks securely into place. Next, turn on the printer and navigate to the "Axis" or "Endstops" menu. Look for the "Y-endstop" option and adjust its setting until the probe triggers smoothly when extended. To confirm proper calibration, print a test object with features that require Y-axis movement, such as a cube or a tower. If everything is calibrated correctly, the printer should move smoothly along the Y-axis without any hesitation or skipping steps.
