FLSUN V400 - 400mm/s at 10k acceleration, PLA 0.15mm

This is a print speed test with the FLSUN V400 after I did some tuning.
Print Speed in Prusa Slicer - 400mm/s for internal and external walls, including the infill.
Acceleration set to 10.000mm/s
Corner speed set to 7
Bambu Lab PLA with 245C
It's still not a real 400mm/s, as the model is too small for the printer to reach those speeds, but the results are quite good.
I didn't have enough filament to complete the print, but I guess the video shows the printer's capabilities pretty well.

Can i have your flsun v400 curra Profile please? Even the new Cura doesnt have It

[@Erbsensuppe22]

wow - what a tremendous presentation of speed

[@matthewwain9958]

Thanks for pushing the prints on this one. Seems like fine tuning will be needed to get the best out of these V400's.

[@tombeardy4833]

well even the bambu x1 needs finetuning :)

[@jasonwu2758]

It it were on the original screen stand, it woulda crab walked off screen due to the table wobble! 😂

[@ssullivan]

Use an infill that doesn't cross to prevent the nozzle scrape

[@Erbsensuppe22]

hi - wich infill mode doesen´t cross?

[@ssullivan]

@@Erbsensuppe22 Gyroid and Rectilinear are the most common

[@TheMoody876]

My ender 3v2 when I first got it triangle infill didn't scrape but now it does

[@ssullivan]

@@TheMoody876 triangle has crossing paths. You could just be extruding more filament than in the past with flow or esteps

[@qozia1370]

But this is not a solution right? Why does it even scrape is the thing we should be focusing on.

[@GraylightSynes]

I'm glad I preordered one! They look extremely capable. What kind of tuning did you have to do to get it to print this well? Anything that you think most owners will have to tweak?

[@googleaccount8578]

Hi, and how is that, good decision ?

Hi. Which camera are you using? Can we use an ip cam

[@Erbsensuppe22]

could somone post the link of that calibration cube - pls

[@Knuckleup-v6b]

sounded like the nozzle was dragging is that normal

[@jeffhack6839]

I noticed that as well. Others have mentioned the same thing. Maybe the speed is causing the extruder to 'tilt' during accel and decel. Extruder is not as solid as with other styles of printer. Just a thought. Cheers.

[@BOOTLEGTOYCO]

What’s the flaws of delta printers? I’m curious because I’m thinking about buying the fl sun super racer for my first printer.

[@C650101]

@@BOOTLEGTOYCO I think there is some loss in resolution due to kinematics

[@Xanthira222]

So what do you think of v400 at the early bird $699 price compared to the Bambu X1?

[@3DPrintBeginner]

You should read my review for a complete understanding. For 700$ it's a good deal. But I wouldn't pay 899$ retail price for it.

[@daliasprints9798]

Delta is a better kinematic system than corexy, but part of what makes it better is the BOM being significantly smaller, belts shorter, etc. which should translate into a much lower price tag. This would be an awesome printer at $450 or so. DIYers could build something at least as good for half that price.

[@Timtam99]

@@daliasprints9798 yeah I agree. Last year I picked up a Flsun SR for $600 AUD brand new , (the older model with a very similar chassis thats just as sturdy and a slightly better motion system coz of linear rails). About $200 of mods and many months of tuning later, it does 300-500mm/s all day at 15k accel. The whole build cost me around 500 USD. Which in my opinion is amazing value for money since it can go crazy fast on pla and abs while also printing cf nylon and a pc since one of the first upgrades I made was a custom enclosure!

Delta printers are more fun to watch:)

[@Nitram_3d]

There's really problems with excessive smoothing in this print.

[@3DPrintBeginner]

Stock input shaper values. Haven't calibrated that yet.

[@Nitram_3d]

@@3DPrintBeginner what scale is this cube.. and speed is decreased on all straight less than 35mm.. if you haven't increased the acell_to_decell

[@3DPrintBeginner]

200%. Both acceleration values are set to 10k. More info in the description

[@foam27]

Hard to tune the machine when it doesn't come with the input shaper sensor you have to order one separately. Once tuned with higher acceleration values using input shaper as well I'm sure it'll be good

[@daliasprints9798]

You should be reaching 400 at that accel - it only takes v²/(2×a) distance to reach v at acceleration a, so 400²/20000=8 mm.

[@foam27]

yeah, why isn't it?

[@riotaken]

maybe cus 50% accel to decel?

[@daliasprints9798]

@@riotaken Good thought - turn that off. (Set it to something higher than any accel you'll ever actually use, like 10000000, so it takes no effect.)
