3D Printer Feed Issue Fix

My desktop 3D printer powers on and heats as expected, yet filament never makes it out of the nozzle. I can’t tell whether the stepper is clicking, the drive gear is slipping, or the hot-end is clogged, so I need an experienced technician to examine it in person. Your job is to track down the root cause and, if it’s something that can be resolved during the visit, fix the feeding problem right away. Bring the standard tools you rely on for extruder, Bowden tube, drive gear, and hot-end maintenance; I’ll provide filament and full access to the machine. Once the feed path is restored, run a quick calibration print so we can confirm smooth, reliable extrusion before you sign off.
