- * Endstop Noise Filter
- *
- * Enable this option if endstops falsely trigger due to noise.
- * NOTE: Enabling this feature means adds an error of +/-0.2mm, so homing
- * will end up at a slightly different position on each G28. This will also
- * reduce accuracy of some bed probes.
- * For mechanical switches, the better approach to reduce noise is to install
- * a 100 nanofarads ceramic capacitor in parallel with the switch, making it
- * essentially noise-proof without sacrificing accuracy.
- * This option also increases MCU load when endstops or the probe are enabled.
- * So this is not recommended. USE AT YOUR OWN RISK.
- * (This feature is not required for common micro-switches mounted on PCBs
- * based on the Makerbot design, since they already include the 100nF capacitor.)
+ * Endstop Noise Threshold
+ *
+ * Enable if your probe or endstops falsely trigger due to noise.
+ *
+ * - Higher values may affect repeatability or accuracy of some bed probes.
+ * - To fix noise install a 100nF ceramic capacitor inline with the switch.
