What kind of Servo or actuator to use for diy filament cutter?

I'm currently looking into upgrading one of my old printers with a filament cutter since filament ramming gives me headaches. It's supposed to be controlled by the printer but I don't find a clear answer what kind of servo or actuator to best use (which is both lightweight but also strong enough). I still have some servo pins available on my board, no stepper though.

Can someone give me a hint what to look for?

How to properly get rid of holes between perimeters?

I'm somewhat puzzled which settings I need to look at in PrusaSlicer to solve those thin slits between perimeters. I've dialed in the flowrate optimally for dimensional correctness and 245°C (PETG) works really well for both flow and overhangs.

At first I thought of extrusion width, but that also increases the distance between each line. Raising the flowrate closes them, but also makes the printed parts grow in each dimension outside if the intended size.

Where am I missing something? Which settings do I need to adjust to not screw up everything else?

EDIT: It's not just corners!

Can mere dirt cause heatcreep?

I'm trying to find the reason why my bigger printer suddenly decided to constantly create blockages as high as the PTFE tube in the cooling block (so a little bit above the heatbreak).

It's an older V6 head. The discolouring on the heating block comes from the single time the nozzle came lose and PETG was pressed through the threads upwards, that was a year ago though. I didn't change anything, from one day to another it just decided that (for both PLA and PETG) it'll now stop working properly.

Waiting on a stronger cooling fan (strongest Sunon I could find, the one with 9000rpm). Other than that I'm just confused why this suddenly happens.

Does the filament path of ruby nozzles degrade + is DUROZZLE any good?

I'm thinkin about getting one of those ruby nozzles for my printers to basically be able to print anything without ever having to worry about a degrading nozzle. I've seen quite a few videos about it, but I still don't know two things:

  • Given the surrounding material is brass and only the tip being out of ruby, doesn't the filament path where the molten filament gets pushed through still wear out over time (heavily so with CF or GF filament)?

And also

  • How good are the cheaper ones, specifically the "DUROZZLE" one (since that's the one I could find that's 0.6mm and cheap)?

"Together we'll make X great again!"

Context: X11Libre is a fork of X11 aiming at preserving the X Server (fair enough, right?). One of the creators got permanently banned from freedesktop.org for apparently violating the Code of Conduct (no info on that, they just blame Red Hat), see themselves as hunted by both Big Tech and "toxic elements" who "took over the X11 project" They want to "make X great again".

The issue about their highly political README (which they wrote due to the original project "becoming too political", lol) also contains the usual red flags like transphobia. https://github.com/X11Libre/xserver/issues/40
