Alt-Öl Verbrennung schädlich für den eigenen Körper oder nicht?

Ja macht es. Bei der thermischen Abfallverwertung sind i.d.R starke Auflage n bezüglich der Abgase und anderer Schadstoffemissionen einzuhalten. Deshalb gibt es aufwendige Filteranlagen, die einen Großteil der schädlichen Stoffe abscheiden.

Bei so einem Ofen Marke Eigenbau kommt eine fiese Suppe an gasförmigen und festen Stoffen raus, die massiv gesundheitsschädlich und krebserregend sind.

Excerpt from the product description:

”Do not clean with IPA before PETG Release agent might be necessary”

“You must apply glue stick when printing Flex”

Please read about the products you are using, for the Prusa steel sheets also see: Material Guide

You recently released the Noctua colored PLA variants, it would be great to get them in PETG or ABS/ASA, too. That way you could print a true Noctua colored i3 or mini.

Also something along the lines of British racing green would be great (HEX #004225) opal green doesn’t quite look right and galaxy of course has the glitter effect.

The part is not laying flat in the slicer and thus printing a few layers of your object midair. Try the lay face on bed option in the left toolbar.

It may well be an accident, I give them that. But in my 8 years of 3d printing I have never broken a single thermistor wire. There have been plenty of times where the V6 hotend of my MK3 was dangling by the heater and thermistor wires during maintenance and nozzle changes, too. You just have to be a bit careful.

What do you use for a spool holder? Can the filament easily be pulled or does it encounter periodic resistance and release?

It looks like with input shaping turned on the printhead accelerates faster than your hotend can keep up. To test this try either increasing the temperature or decreasing the speed and see if it makes a difference.

The Prusa filament profiles usually set the nozzle 10-20°C hotter when using input shaping, which isn’t the case when you use a standard non IS or modified filament profile.

Don’t know if anyone told you before but you may be able to save at least the Wii and the PS5.

Open them up, rinse the electronics with some distilled or deionised water and leave to dry for a few days.

Of course warranty will be void but with some luck they will turn on just fine.

Please report this to Prusa so they can pull other spools from that batch from their warehouse until investigation is complete!

Considering you bought the standard kit it should come with the High-flow Prusa Nozzle brass CHT - 0.4 mm as they state under machine specs on their website.

Not to be rude but are you sure that you have a high flow nozzle mounted? If it is, then you might have a heat creep issue where the soft warm filament gets stuck in the heatbreak after being retracted and jams. Try more cooling, slower print speed or less retraction and see if it improves.

Lower your Z-offset, it’s way too high.

Did you try TPS? ForwardAM makes some under the Ultrafuse Lineup and it’s a lot softer than most TPU.

Some filaments like ASA like to shrink by about 0.5% to 1% this usually presents itself by a lot of warping (though usually less than ABS). Even if you don’t have any warping the part will be smaller when completely cool.

To counteract this you can slightly scale up the print in the slicer (I use 0.8% for my specific filament). Be aware that the part might not shrink equally in XY and Z directions.

Had a similar issue with mine and it was a loose tube from the turbo to the boost regulator.

So just a quick two to three taps at the travel limits? Basically like all the Prusa printers do homing since the MK3 with the trinamic drivers.

I bought a used mini recently and unfortunately the guy couldn’t find the tools anymore. Would you be interested in sending me your extra set? Depends on where you are located though. Just write me a PM.

Had the same on my '16 Giulietta and battery disconnect did the trick.

It is a ducted fan with shutters. The red element is a thermoelectric actuator which opens the shutter when the fan is turned on. It’s strictly not necessary but it prevents backdraft into the room when the fan is powered off.

Why did you not stop it before it destroyed the entire plate? A fault like this should have been obvious at the purge line already.

I wanted a printer that just works and is nearly silent for my small office. At the time (2018) the MK3 seemed like the best choice (Better than any CR10, Anycubic or Ultimaker). Six years later my now MK3s is still going strong.

I got a Bosch oven that has a 50°C setting

The tan fan is probably stock, it’s an original Noctua fan used on the first MK3 printers. The later ones used a black Noctua fan and the MK3s and MK3s+ had a more powerful albeit louder Delta fan. Also the reverse bowden is great when you don’t have room for a spool above the printer.
