FYSETC 1pcs Voron 3D Printer original design Hall Effect Sensor limited switch high quality Voron 2.4 endstop For X/Y Axis Hall effect endstop board for X and Y axes The Hall Effect board allows for contactless homing on the X and Y axis on a Voron 2.When hall sensor reaches close to magnet it produces a voltage. The circuit then compares that with a reference voltage. The comparator flips based on threshold set using the trim pots. Please follow following procedure to setup Hall Effect Board. Make sure both the pots are centered. Then take a magnet for x axis.Try both the poles. Find the pole of magnet that triggers sensor within 1 inch of magnet. Install the X magnet into afterburner carriage. Please repeat the same process for Y axis and then install it in zblock.
