I mostly do my own work, but whenever I do take my car to the local Mazda dealer, they always provide a full inspection report as well as a video of the tech checking everything and explaining anything that they’ve found. Even when my wife takes her car in for only basic maintenance (it’s still under warranty so we take it in for oil changes), they do the same thing and don’t charge anything extra.
Same dealer network owns the local Ford dealer and I ended up taking my old Fiesta ST there for an oil change as I didn’t have the space to do it myself at the time. $45 for an oil change and tire rotation, and I got the same inspection report and video.
I had something like this happen to me recently on my Ender 3 Max Neo. My filament feeds from a separate dry box and the spool was slightly crooked. Once the angle from the box to the extruder got too severe, the spool bound up and wouldn’t feed anymore. Moving the spool so it properly rested on the rollers fixed it.
