When the Z-axis fails to home, triggers a servo alarm, or loses height-following capability, cutting quality and machine operation are affected. This guide explains the main causes and proven solutions to restore stable Z-axis performance quickly.<\/p>\n<h3 data-start=\"758\" data-end=\"799\">Common Causes of Z-Axis Servo Alarm<\/h3>\n<h4 data-start=\"801\" data-end=\"844\"><strong data-start=\"806\" data-end=\"844\">1. Limit Switch Trigger or Failure<\/strong><\/h4>\n<p data-start=\"845\" data-end=\"1050\">If the positive or negative limit switch is triggered, the system will lock movement and show an alarm. In many cases, dust, oil, or metal debris may block the optical limit switch, causing a false signal.<\/p>\n<p data-start=\"1052\" data-end=\"1060\"><strong data-start=\"1052\" data-end=\"1060\">Fix:<\/strong><\/p>\n<ul data-start=\"1061\" data-end=\"1161\">\n<li data-start=\"1061\" data-end=\"1090\">\n<p data-start=\"1063\" data-end=\"1090\">Clean the limit sensor area<\/p>\n<\/li>\n<li data-start=\"1091\" data-end=\"1129\">\n<p data-start=\"1093\" data-end=\"1129\">Unplug and reconnect the switch wire<\/p>\n<\/li>\n<li data-start=\"1130\" data-end=\"1161\">\n<p data-start=\"1132\" data-end=\"1161\">Replace the switch if damaged<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"1163\" data-end=\"1239\">Typical symptom: machine cannot return to home or shows \u201cover-travel\u201d error.<\/p>\n<h4 data-start=\"1241\" data-end=\"1275\"><strong data-start=\"1246\" data-end=\"1275\">2. Mechanical Home Offset<\/strong><\/h4>\n<p data-start=\"1276\" data-end=\"1396\">After sudden power loss, the Z-axis zero position may shift. Incorrect zeroing can cause alarms or movement restriction.<\/p>\n<p data-start=\"1398\" data-end=\"1406\"><strong data-start=\"1398\" data-end=\"1406\">Fix:<\/strong><\/p>\n<ul data-start=\"1407\" data-end=\"1585\">\n<li data-start=\"1407\" data-end=\"1464\">\n<p data-start=\"1409\" data-end=\"1464\">Power off the machine, wait a few minutes, then restart<\/p>\n<\/li>\n<li data-start=\"1465\" data-end=\"1498\">\n<p data-start=\"1467\" data-end=\"1498\">Perform mechanical homing again<\/p>\n<\/li>\n<li data-start=\"1499\" data-end=\"1585\">\n<p data-start=\"1501\" data-end=\"1585\">Check Z-axis stroke settings (e.g., BCS100 controller F2 parameter typically \u2264 75mm)<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"1587\" data-end=\"1663\">This prevents false travel-limit alarms and ensures accurate height control.<\/p>\n<h4 data-start=\"1665\" data-end=\"1707\"><strong data-start=\"1670\" data-end=\"1707\">3. Servo Driver or Encoder Issues<\/strong><\/h4>\n<p data-start=\"1708\" data-end=\"1796\">The servo driver will display error codes if the motor or feedback signals are abnormal.<\/p>\n<p data-start=\"1798\" data-end=\"1806\"><strong data-start=\"1798\" data-end=\"1806\">Fix:<\/strong><\/p>\n<ul data-start=\"1807\" data-end=\"2028\">\n<li data-start=\"1807\" data-end=\"1859\">\n<p data-start=\"1809\" data-end=\"1859\">Note the alarm code and refer to the driver manual<\/p>\n<\/li>\n<li data-start=\"1860\" data-end=\"1911\">\n<p data-start=\"1862\" data-end=\"1911\">Shut down the machine for 5\u201310 minutes and reboot<\/p>\n<\/li>\n<li data-start=\"1912\" data-end=\"1977\">\n<p data-start=\"1914\" data-end=\"1977\">Inspect encoder cables and plugs for looseness or contamination<\/p>\n<\/li>\n<li data-start=\"1978\" data-end=\"2028\">\n<p data-start=\"1980\" data-end=\"2028\">Replace damaged motor\/encoder cables if required<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"2030\" data-end=\"2120\">A faulty encoder or loose connector may lead to \u201cNo Response\u201d or unstable Z-axis movement.<\/p>\n<h4 data-start=\"2122\" data-end=\"2183\"><strong data-start=\"2127\" data-end=\"2183\">4. Height Controller (Capacitive Sensor) Abnormality<\/strong><\/h4>\n<p data-start=\"2184\" data-end=\"2308\">A sudden sensor capacitance value drop to zero or irregular fluctuations indicates a failure in the height-following system.<\/p>\n<p data-start=\"2310\" data-end=\"2318\"><strong data-start=\"2310\" data-end=\"2318\">Fix:<\/strong><\/p>\n<ul data-start=\"2319\" data-end=\"2439\">\n<li data-start=\"2319\" data-end=\"2379\">\n<p data-start=\"2321\" data-end=\"2379\">Check nozzle and ceramic ring installation and cleanliness<\/p>\n<\/li>\n<li data-start=\"2380\" data-end=\"2415\">\n<p data-start=\"2382\" data-end=\"2415\">Inspect sensing head and RF cable<\/p>\n<\/li>\n<li data-start=\"2416\" data-end=\"2439\">\n<p data-start=\"2418\" data-end=\"2439\">Replace damaged parts<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"2441\" data-end=\"2513\">Incorrect nozzle mounting and contaminated ceramics are common triggers.<\/p>\n<h4 data-start=\"2515\" data-end=\"2565\"><strong data-start=\"2520\" data-end=\"2565\">5. Mechanical Interference or Obstruction<\/strong><\/h4>\n<p data-start=\"2566\" data-end=\"2638\">Even if no alarm code appears, mechanical resistance can stop the servo.<\/p>\n<p data-start=\"2640\" data-end=\"2648\"><strong data-start=\"2640\" data-end=\"2648\">Fix:<\/strong><\/p>\n<ul data-start=\"2649\" data-end=\"2792\">\n<li data-start=\"2649\" data-end=\"2702\">\n<p data-start=\"2651\" data-end=\"2702\">Check Z-axis guide rails, ball screws, and bearings<\/p>\n<\/li>\n<li data-start=\"2703\" data-end=\"2750\">\n<p data-start=\"2705\" data-end=\"2750\">Remove chips or debris from the motion system<\/p>\n<\/li>\n<li data-start=\"2751\" data-end=\"2792\">\n<p data-start=\"2753\" data-end=\"2792\">Ensure no bending or mechanical jamming<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"2794\" data-end=\"2874\">Noise from the motor or jerky movement usually means mechanical friction exists.<\/p>\n<h3 data-start=\"2794\" data-end=\"2874\">Step-by-Step Troubleshooting Checklist<\/h3>\n<table style=\"width: 68%; height: 216px;\">\n<thead>\n<tr style=\"height: 24px;\">\n<th style=\"text-align: center; height: 24px;\">Step<\/th>\n<th style=\"text-align: center; height: 24px;\">Action<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"height: 24px;\">\n<td style=\"text-align: center; height: 24px;\">1<\/td>\n<td style=\"text-align: center; height: 24px;\">Power off 5\u201310 minutes and restart<\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"text-align: center; height: 24px;\">2<\/td>\n<td style=\"text-align: center; height: 24px;\">Re-home Z-axis and verify zero point<\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"text-align: center; height: 24px;\">3<\/td>\n<td style=\"text-align: center; height: 24px;\">Check and clean limit switches<\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"text-align: center; height: 24px;\">4<\/td>\n<td style=\"text-align: center; height: 24px;\">Verify Z-axis stroke parameters<\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"text-align: center; height: 24px;\">5<\/td>\n<td style=\"text-align: center; height: 24px;\">Inspect servo driver alarm code<\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"text-align: center; height: 24px;\">6<\/td>\n<td style=\"text-align: center; height: 24px;\">Examine encoder wiring &amp; connectors<\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"text-align: center; height: 24px;\">7<\/td>\n<td style=\"text-align: center; height: 24px;\">Check capacitance &amp; sensor components<\/td>\n<\/tr>\n<tr style=\"height: 24px;\">\n<td style=\"text-align: center; height: 24px;\">8<\/td>\n<td style=\"text-align: center; height: 24px;\">Inspect mechanical transmission parts<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>If the servo alarm remains after the above steps and no mechanical blockage is found, contact your machine manufacturer or technician.
