Filament Sensor Replacement Kit(2Pcs) Compatible with Snapmker U1: PCB Board Module with Cable for Detecting Supply Status of Consumables in Hotend Extruder 3D Printer Accessories

["Only include filament sensor, no whole filament run-out detection assembly. Specially designed for snapmake-U1 3D printing project, can directly replace broken original, plug and play","The function of the filament sensor is to detect the presence of consumables in the extruder. It is located on the tool-head, which prevents printing faults and improves printing efficiency and material breakage detection","It is to pause the printing process immediately when the filament runs out, this prevents the printer from continuing to move with no material, which would result in a failed print and wasted time","When printing with multi-color filaments, the PCB circuit board recognises when consumables are being fed in and out and transmits the information to printer for switching between consumables, as well as detecting if there is a blockage and responding with information to the printer","Easy to install, firstly press fitting to remove ptfe tube, then separate the print head from the converter, disconnect the wires from the components on the control board, remove the print head control board, and pull out all the cables from the extruder unit' s cable clamp, remove the extruder unit and bearings, and finally remove filament run-out detection component, replace the filament sensor"]
