How do I remove filament from the hotend of a direct-drive printer?

I have PrintrBot Simple Metal and over the course of today's use, I managed to get a piece of filament stuck in the hotend, just below the extruder gear. There's not really much to grab at, and my tweezers aren't that strong. How should I go about…

How to distinguish filament runout and filament jam using a microswitch-based filament sensor in Marlin?

I found two great designs for a DIY sensor that achieve both filament runout and filament jam detection in one unit. A clever design that only uses one microswitch as follows: Source: Thingiverse.com Another design using two microswitches, as…

Which detection mechanisms can a filament sensor use?

Using the official Creality runout sensor, I encountered a few times that the filament entangled around something and got stuck, the printer continuing for several hours (as it didn't run out), printing mid-air aithout filament. Then I got…

Ender 3 Pro extruder keeps clogging

I'm fairly new to 3D printing and looking for help. I have an Ender 3 Pro and it's been working great up until about a week ago. When I preheat the extruder, the nozzle gets hot as it should, but it keeps jamming mid-print. About an hour in, the…

Prusa i3MK3S+ layer skip with polycarbonate (overheating?)

On the last couple of polycarbonate prints with my Prusa, one or more layers have been completely skipped (i.e. no material extruded). The rest of the print is fine save some minor warping. I'm printing in an enclosure that gets up to ~60 °C with…

How can printer firmware use encoder wheel data?

I am trying to understand the concept of the encoder wheel used as a filament sensor, as shown below. It can detect if filament is moving, making it suitable for filament runout and filament jam detection, although it wouldn't be able to distinguish…
