Capacitive sensor FAILS <br /> <br />Zero on the left of the bed is set perfect but moving to the right the nozzle is about 1mm above the bed when zero is selected. <br /> <br /> It appears that this sensor is triggering at different distances depending the position on the build plate. <br /> <br /> If it sensors the distance then it should be the same distance from the bed when set to zero. Even if the build plate is not physically level. <br /> <br />LJC18A3-B-Z/AY PNP NC 3-Wires 10mm <br /> <br />Capacitive Proximity Sensor Switch DC 6-36V <br /> <br />Product Name: Proximity Switch <br /> <br />Specifications Model: LJC18A3-B-Z / AY <br /> <br />Outside diameter: Φ18 <br /> <br />Dimensions: 78 x 30mm/3.07 x 1.18"(L x Dia) <br /> <br />Total Length:127cm/50" <br /> <br />The detection method: Capacitive <br /> <br />Detection range: ± 10mm (mm) <br /> <br />Operating voltage: DC6-36V <br /> <br />Output Type: PNP NC(normally closed) 3 Wire <br /> <br />Color:Grey and Silver <br /> <br />Weight:86g <br /> <br />eBay seller : gobuyteam <br /> <br />Proximity sensors, however, is the trouble they have compensating for changes in the environment over time. Changes in <br />humidity, for example, dirt collecting on the sensor area, or a change in the moving object can impact sensitivity and reduce performance. <br /> <br />http://www.nxp.com/documents/white_paper/NXP_DigiKey_CapacitiveSensors.pdf <br /> <br />Protomaker Black Sprint Original 3D Printer <br /> <br />Protomaker 3D Printer was advertised for spares or repairs. <br /> <br />It may take some time to get this 3D printer working to a level where it is usable due to lack of budget. <br /> <br />Powder Coated Mild Steel Structure With Acrylic Build Platform <br />Product Type : All In One Printers <br />Cartridge Type : Original <br />Utility : 3d Printing <br />Printing Output : Colored <br />Print Technology : Fused deposition modelling (FDM) <br />Size : Large <br />Other Features : Powder Coated Mild Steel Structure With Acrylic Build Platform <br /> <br />SUPC: SDL051787633 <br /> <br />My Wordpress Blog will tell you more about:- <br /> <br />Protomaker Black Sprint Original 3D Printer <br /> <br />https://protomaker3dprinter.wordpress.com/ <br /> <br />Tweets about 3D Printers: tips, hardware software, filament ,etc... <br /> <br />https://twitter.com/myvideostowatch <br />.
