First of all: Legal is the bare minimum.

If you run a contest or sweepstakes and set out rules you are bound to them. Ignoring them like Prusa did exposes you up to liability claims.

You’re mad that the contest was moderated?

More the opposite. The sloppy way they moderate it to the point where they don't even bother to remove comment spam below the contest description page.

Voters voted on the submissions they liked the most. Get over it. Voters voted on the submissions they liked the most. Get over it.

That's not how it works. There is no public vote.

Honestly I stopped reading. Something about a paid part integration that you got mad about because it’s heavily discounted and you can submit photos even if you don’t have one or something?

Just read the comments here: https://blog.prusa3d.com/contest-experiential-robotics-challenge_97306/

Dozens feel like this isn't a good choice.

Btw. I don't take part in them but it is still very ugly what they do. Similiar you don't need to buy Nestle to understand that Nestle might be problematic in some aspect.

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): https://www.wahl-o-mat.de/europawahl2024/app/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.

I don’t lube the rails, it attracts too much dust. I still oil them to prevent rust.

The 50km figure is out of the HiWin application note at 30% load capacity. Even with 0% load it won't go above 150km.

Looking at the Thompson-Link: It is for the self-lubrication block (long-term lubrication unit) which indeed has a much higher endurance. Raising maintenance intervals to roughly once per year. As far as I know, they are only available for MGN15 and larger.

has a maximum flow rate of 22 mm^3/s which limits it to about 250mm/s for 0.2mm layer height.

Divide the number by 5 which would be roughly every 100 print hour or two weeks of printing.

Marlin has this feature (time based) but most manefacturer didn't enabled it.

Duet doesn't have it

Klipper doesn't (has a time counter so you could implement it easily).

Printers are pushing significantly faster acceleration these days with upto 50k mm^2/s and 1m/s is already real.

Works for me.

It allows me to post a make.

Some aspects of Printables are "wrong". Contests are a total mess at the moment. I might make a serape post about it.

This? Looks like a glitch/bug. As far as I can tell this is only active on paid items which makes sense.

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.

Thanks. See the other comment for details how now performs.
