It scrapes the PEI sheet, the printer throws a height or \"Key 2401\" error, and your first layer is either crushed into the plate or floating in mid-air.

When the pressure sensor fails, that convenience disappears and the nozzle can damage the build plate. Replacing the sensor restores hands-off calibration, so you can go back to printing a set of PLA desk organisers without babysitting the first layer.\u003c\/p\u003e\n\n\u003ch3\u003eSchools running several SE or KE printers\u003c\/h3\u003e\n\u003cp\u003eClassroom printers get bumped, moved and run by many users, and a printer with unreliable levelling wastes lessons. A replacement sensor brings a machine back to automatic calibration, so learners press print and get a usable first layer. A class can print its batch of PLA keyrings without a teacher adjusting Z offset machine by machine.\u003c\/p\u003e\n\n\u003ch3\u003eSmall print farm operators\u003c\/h3\u003e\n\u003cp\u003eOn a farm of \u003ca href=\"https:\/\/3dprintingstore.co.za\/products\/creality-ender-3-v3-ke-3d-printer\"\u003eCreality Ender-3 V3 KE 3D Printer\u003c\/a\u003e machines, every printer needs to calibrate itself identically. One faulty sensor means one printer producing crushed or loose first layers and failed plates. Swapping the sensor brings it back into line, so a run of 30 PETG cable clips adheres consistently across every machine.\u003c\/p\u003e\n\n\u003ch2\u003eWhat sets the Ender-3 V3 SE and KE bed-levelling sensor apart\u003c\/h2\u003e\n\n\u003ch3\u003eA first layer you never have to set by hand\u003c\/h3\u003e\n\u003cp\u003eThe Ender-3 V3 SE and KE use two sensors to calibrate. The CR Touch probe maps the shape of the bed, and this pressure sensor sets the Z offset, the exact gap between nozzle and bed at the start of a print. During calibration the nozzle gently presses on the bed, and the sensor detects the moment of contact. The printer then stores that height as its offset. With a working sensor, you never need the paper test or live Z adjustments, and the first layer comes out right after a nozzle change, a plate swap or a move.\u003c\/p\u003e\n\n\u003ch3\u003eStrain gauge sensing for precise contact detection\u003c\/h3\u003e\n\u003cp\u003eThe sensor uses a \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Strain_gauge\"\u003estrain gauge\u003c\/a\u003e, a thin resistive element whose resistance changes as it bends under load. The same principle used in a \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Load_cell\"\u003eload cell\u003c\/a\u003e lets the printer detect the small force of the nozzle touching the bed. Because it measures the actual contact between nozzle and surface, it accounts for nozzle length and plate thickness automatically. A damaged or drifting gauge reports contact too late or not at all, which is why a failing sensor causes the nozzle to drive into the bed instead of stopping.\u003c\/p\u003e\n\n\u003ch3\u003eProtects your build plate and nozzle\u003c\/h3\u003e\n\u003cp\u003eWhen the sensor misreads, the nozzle keeps descending until something gives. That usually means a gouged PEI surface, a bent spring steel sheet or a damaged nozzle tip. Forum reports from SE owners describe heated beds badly scored during failed auto Z offset runs. A correctly working sensor stops the nozzle at first contact, so calibration is gentle on your plate. Replacing a suspect sensor early is far cheaper than replacing the build surface and nozzle it damages.\u003c\/p\u003e\n\n\u003ch3\u003eGenuine part, matched to the factory firmware\u003c\/h3\u003e\n\u003cp\u003eThe SE and KE firmware expects a specific signal from this sensor to trigger contact. This genuine Creality part, number 2101030196, is the factory component for both printers, so calibration thresholds work as designed and you do not need to modify firmware settings. It fits under the print bed in the factory position and connects to the existing wiring, keeping your printer identical to the original build in \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Fused_filament_fabrication\"\u003efused filament fabrication\u003c\/a\u003e performance.\u003c\/p\u003e\n\n\u003ch2\u003eFull specifications: Ender-3 V3 SE and KE bed-levelling sensor\u003c\/h2\u003e\n\u003ctable style=\"border-collapse: collapse; width: 100%;\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"padding: 6px; text-align: left;\"\u003eSpec\u003c\/th\u003e\n\u003cth style=\"padding: 6px; text-align: left;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003cstrong\u003eGeneral\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eBrand\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eCreality\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eProduct\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eBed-levelling sensor (strain gauge) for Ender-3 V3 SE and KE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eStore SKU\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eCRE787\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eManufacturer part number\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e2101030196\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003cstrong\u003eHardware\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eSensor type\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eStrain gauge pressure sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eFunction\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eDetects nozzle contact for automatic Z offset calibration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eLocation\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eUnder the print bed, factory mounting position\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eWorks with\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eBuilt-in CR Touch probe (bed mesh)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003cstrong\u003eSoftware\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eFirmware\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eFactory SE and KE firmware, no changes required\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003cstrong\u003eCompatibility\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003ePrinters\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eCreality Ender-3 V3 SE, Ender-3 V3 KE\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003eNot compatible with\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003eEnder-3 V3 (CoreXZ), V3 Plus, K1 series\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003cstrong\u003eIn the box\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 6px;\"\u003ePackage contents\u003c\/td\u003e\n\u003ctd style=\"padding: 6px;\"\u003e1 × bed-levelling strain gauge sensor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eOrdering, shipping and support for Ender-3 V3 SE and KE sensors\u003c\/h2\u003e\n\u003cp\u003eWe courier the Ender-3 V3 SE and KE bed-levelling sensor to any address in South Africa, or you can collect it from our Centurion or Boksburg store.

The CR Touch probe measures the shape of the bed to build a mesh, while this strain gauge sensor detects nozzle contact to set the Z offset. If bed mesh probing fails, suspect the CR Touch. If the nozzle crashes during Z offset calibration, suspect this sensor.\u003c\/p\u003e\n\n\u003ch3\u003eMy printer shows \"Key 2401\". Do I need a new sensor?\u003c\/h3\u003e\n\u003cp\u003eNot necessarily, so try the free fixes first. Australian distributor DREMC reports that some users cleared this error with a firmware update or factory reset. It can also come from the CR Touch failing to trigger. If the error persists after both, or the nozzle presses into the bed, replace the sensor.\u003c\/p\u003e\n\n\u003ch3\u003eCan I fit this to an Ender-3 V3 or V3 Plus?\u003c\/h3\u003e\n\u003cp\u003eNo, this sensor is made for the Ender-3 V3 SE and Ender-3 V3 KE only. The CoreXZ Ender-3 V3 and V3 Plus use a different levelling system. Check your printer's model label before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eHow difficult is the replacement?\u003c\/h3\u003e\n\u003cp\u003eIt is a moderate screwdriver job that involves working under the bed. Power off and unplug the printer, remove the build plate and bed fixings to reach the sensor, then disconnect and swap it in the same orientation. Reassemble, then run the full auto-levelling routine and print a first-layer test.\u003c\/p\u003e\n\n\u003ch3\u003eIs local warranty and support available?\u003c\/h3\u003e\n\u003cp\u003eYes, genuine Creality parts carry the manufacturer's warranty, handled locally by our South African support team.
