For Germean voters there is the WahloMat to help with the voting choice (a dozen of questions and in the end shows how much overlap there is with all the parties): www.wahl-o-mat.de/europawahl2024/…/main_app.html
The major issue is that if you care about CopyRight: Party A. Easier to comply with regulation: Party B. Migration: Party C. Environment: Party D.
And all of the choices (A-D) have some very removed, prominent positions that you strongly oppose and in the end, have no clue what to elect and choose the least worst option and hope for the best.
If cold pulls won’t work get a new nozzle. Filament of choice for this procedure is Nylon.
One of the alternatives could be THF to dissolve the plastic and go from there. Don’t know what Prusa charges for nozzles but it can’t be that bad to make this procedure worth it. After all it is a Prusa and not some industrial machine.
Prusa is very slow compared to Cura as PrusaSlicer needs every option checked including Geometry handling accurate to sometimes get 7 pcs. matching Cura performance. If the result is 7 or 6 pcs. depends on where the part originally was placed on the print bed (or luck? run to run variance?). Not a reliable software for nesting.
With fast and balanced setting it only does 6 pcs.
With mainsail and klipper, you can cancel one failed part mid-print and keep going on the rest of the parts.
There is an addon for Duet (RRF) but I can’t get it working. Anyway, once it is time for a batch print the first testprint has been completed successfully and build plate adhesion is a non-issue on this printer.
You have to tell it the dimensions of your extruded head, so it doesn’t crash the part Ask me how I destroyed two z-endstops this year (very asymmetrical toolhead and Prusa can’t be configured to reflect this and with a “radius” large enough it would block half of the printbed (60mm radius or so) meaning eyeballing is the best option).
I only use this option if I need the part before the entire batch is finished and don’t want to start multiple prints. Which isn’t frequent.
Cars are a very high-vibration environment with km of wiring and some carrying high currents, flammable liquids and hot parts. With e-autos there is even more including a 50’000 Wh energy storage waiting to catch fire.
While cars do catch fire it is unlikely to the point where they don’t need fire suppression systems.
Some cars have fire suppression systems but those are race cars. Built differently to maximize performance. (or military vehicles)
Similiar there are 3D-printer that might benefit from a fire suppression system but the run of the mil 3D-printer won’t need it.
Not convinced? Look at CNC-mills or swiss lathes. Those are designed to run nonstop for years in a production environment at the highest speeds to maximize production. Most of them don’t have a fire suppression system (they do have a mist extraction/collector to prevent them from exploding).
I like BambuLab. They handled the issue seriously. Resolved it and now it is fixed.
What I meant with low end China is like QIDI-tech having exposed 230V (not fixing it), Tronxy choosing high and low voltage wires with the same color and no PE connection to the chassis, Ankermake having issues with the heatbed insulation (not fixing that either) and crushed wires. That’s just three examples and don’t expect that other companies are better. BambuLab is a rare exception.
Once you teardown “industrial”/professional machines the point of view changes: PE connections, strain relief, drag chain rated cables with appropriate bend radius, crimped ferrules instead of solder on wire ends, … they are built to last and run 24/7 without catching fire…
The best protection is a machine that is well build:
We have ovens in our kitchens that are designed to reach upto 400°C (for cleaning) and nobody is afraid of them catching fire. Why? They are engineered to be safe.
Similiar a 3D printer that has good engineering is safe and doesn’t require an automatic fire extinguisher.
If we talk about low-end China printers then the answer is they might not be as safe but the solution is to fix them instead of adding the fire suppression system.
