@@OldCurmudgeon3DP PLA requires significantly more cooling, it retains tons of heat and the glass transition temperature is much lower than other materials, so take more effort to cool properly compared to something like ABS. PETG is also easier to cool, but the difference is smaller and the flow rate is worse.
In addition to the Speed Benchy videos, I would love to see a video showing the best quality you can achieve with reasonable print speeds. I mean Speed Benchy is fun and all, but at the end of the day you're not producing anything that can actually be used at those speeds.
It does sound like it is trying to take off! but if you only have to deal with it for 5 minutes, maybe it is not that big a deal.... Now here is a question for this 'speed boat' race, what determines what is an acceptable (fair) benchy? I have do a couple of quick (not really) printers that can blow filament all over the place, but what/who determines what a 'good' benchy is?
Watch the video from Annex Engineering explaining the rules. The goal is not a "good" benchy, but a "fast" benchy. It provides huge insights into the bottle necks of your printer and design.
I'm getting 6:48 on my V0 with 400mm/s speed, 45k acc and 60 SQV. Other settings for benchy itself are the same as yours. Strange. I'm using OrcaSlicer, but could you maybe share your 3mf so I could discover what's wrong?
@@miklschmidt if this is beta then I may have to retire my Ender 3 when mine arrives. Best so far has been 25min and that one didn't complete due to layer shifting.
@@OldCurmudgeon3DP A proper rail implementation and stepper upgrade on the Ender 3 will properly help a lot there. But yeah, smaller will always be faster, and the minion is made of much beefier components :)
@@miklschmidt Klipper and TMC steppers were the best upgrades so far I think. Direct drive helped also. I have the board for resonance tuning just haven't gotten to that yet. Ringing is an issue above 3k accel too. I added a 2nd 5015 to the part cooling since I ran my last test.
Indeed. This was solely for speed of course. The Dragon HF can barely keep up, infill is severely under extruded, and the infill type doesn't lend itself great as support for the top layers. But.. It finished! :D
"I'm really fast at math." "Oh? What's 48*7?" "22" "That's nowhere close to correct." "Yeah, but it was fast." Impressive speed means nothing if the end result is unusable. Impressive for such a small machine, not impressive from a usability standpoint.
@Aidan Cunningham I don't get it then? Is the point to race who can make garbage the fastest? Like, should there not be a quality requirement in there? Am I insane for thinking that racing to make unusable parts is not useful (or fun) in the least? O.o
@@Tuskengod Teaching Tech described it nicely here: th-cam.com/video/6kRjdprTjFc/w-d-xo.html. It's more about pushing yourself and the printer to 269% to set the new baseline - you are right thinking that no one will print in this "quality" but now his printer is tuned to print in 140% of the speed he had before the challenge. (numbers I'm giving here are made up to make an example)
@@8-bitairhead62 i don’t agree. If you saw this print you’d immediately recognize a benchy. People are completely missing the point of speed benchies. The goal isn’t to produce perfect prints at super high speeds. The goal is to push the printers to their current limit and optimize it so we can continue to improve them. If you can print this kind of benchy in this time, you can print nearly perfect benchies if you increase the time. THAT’S the point.
Well guys I guess that’s official coz he says it doesn’t count. You better stop all this crazy R&D, trying to find and remove the bottle necks, trying to build n support the community, having fun (pfffft!). Who’d have thought a few metres of plastic could invoke such feelings 🤣
Awe-freaking-some!! Even more since its pla. Good work there.
Thank you so much, Simon!
Is PLA that much harder than the other types? It and PETG are all I work with.
@@OldCurmudgeon3DP for highspeed benchy..yes. it needs tons of cooling. Its glass transition point is way lower than abs.
@@Vez3D I should try PETG then. Less cooling than PLA. ABS doesn't have a seat at my table.

Count it! Great print with the PLA. That is one fast bedslinger for sure!

That's crazy on a cantilever bed Slinger well done
Cannot wait to get mine so excited
Forget the benchy. Who makes your filament? I love that cardboard spool.
I get it from 3DEksperten in Denmark, not sure where they source it though :)
Your mobile looks like it needs some love!
I liked that warning at the beginning :D
Yeeeeaah, i'm to stingy to pay for a replacement screen 😂 Will prolly swap for the next iPhone, lol. I'm a shill! 😂
i need to see the slicer settings for this! i have no idea how you achieved this! i am attempting the same with 9min results using your settings lol!

That's some proper speed. 💪👍
Production version of minion with LGX lite will be faster?
What fans are you using? Never heard a 5015 that loud at 5v, 12v or 24v
This is the Delta BCB0812UHN-TP09, a 27W, 3.675 in. H2O, 30CFM 75x80x30 blower :) Takes a lot of air to cool PLA :D
Brill I love watching these
Could it do a decent quality benchy in say 18 minutes ??????????????
whats the point of super high speed if the quality is so bad?
That's an awesome model of a shipwreck. Where did you get it? 😝 Anyways, this is awesome, for a slinger. Kudos...
There’s a lot of bounce in the arm. Judging by the results that must be the whole printer bouncing. Is my BBC assumption correct?
Pretty much!
holy crap I can visibly see the end of that cantilever x axis shaking up and down that poor thing!
Possibly, but more than that probably the whole thing shakes. Holds up beautifly.
@@pkucmus tbh it looks like it's moving different to the bed but at the same time cameras aren't great.
Neat, how big is that bed?
180x180 :)
Do people print anything other than benchys?
when is this printer going to be available???
No official release date yet, still in BETA, but we're getting closer everyday 😂

@@OldCurmudgeon3DP Ringing will be mitigated significantly with Input Shaper, and it'll probably help a lot with rails too.
How much do the optional bedrock supports cost?
I was waiting for it to fly away when I heard the fans speed up lol
will it float.....
Does a regular benchy float? 😅
@@miklschmidt yes... But upsidedown....
@@Nitram_3d Hahaha, maybe we need to start printing the bathtub boats instead! :D
i see, the electronics are external, thats smart
For their lifespan I presume you mean :D
Still you cant expect quality when you doing a test like that....that is out there for sure. Cant believe how fast it can go

ridiculous LOL
lol beast
It looks disgusting but impressive nonetheless :-)
sexy
..sooo it looooks like.. a turd.
ok, is it an acceptable benchy? NO, so it doesn't count
That's not in the #speedboat rules. Looks are "extra points". Also keep in mind this is PLA.
You do a better looking benchy on a bedslinger then, in the same time. Then comment.
Well, the rules allows it so it does count, but yeah it barely resembles a benchy....
