The text appears to be a set of instructions for modifying an extruder on a 3D printer. The modifications include adjusting the filament tension, installing a run-out sensor, and adding a filament oiler. Here is a summary: **Adjusting Filament Tension** * Use a stronger spring if available * Create an "adjuster" by placing a bolt, nut, and washer in the extruder well to increase pressure on the bearing * Reassemble the extruder and check that more force is being applied **Run-out Sensor** * Connect a tact-switch to the control board using wire and solder * Snap or bend off unwanted pins from the switch * Press-fit the switch into its housing in the extruder body * Use a multi-meter to test the switch's actuation with filament present and absent * Glue the switch in place once it is reliable **Filament Oiler** * Clean and lubricate the filament using WD-40 and a cloth * Install the oiler below the extruder, inserting a piece of cloth or cotton wool into the well * Add a few drops of WD-40 to the oiler and replace the lid * Run the filament through the oiler to test its function Overall, these modifications aim to improve the reliability and performance of the extruder on the 3D printer.
