Voron 2.4r2 350 printing PETG at over 300mm per second

[@Lyrik8805]

Only issue is that you're not actually getting 300mm/s because the accel is too low to allow the printer to reach that speed before it has to deceleratate and/or change direction.

[@richardbreiner894]

Came here to say this, thank you. He needs to up his acceleration to 20,000 and post another video 😂

[@B10KPlaysGames]

Did I miss the part where the printer was actually printing at 300mm/s?

[@wintertod74]

he never said he would

[@AlexanderGaines-bd9yl]

My printer looks twice as fast printing at 200

[@michits1118]

Its because he has a low accel

[@weberengraving3d]

We wanted to test out the bambu x1c and went to 664mm/s perimeter and 996mm/s infill for the xyz Cali cube

[@weberengraving3d]

With 10.000mm/s²

[@ALLYOURTECH3DP]

The X1C is a damn impressive machine! My Voron being a 350mm build has quite a bit more mass to move around which limits speeds slightly

[@aaronhambek6362]

@@ALLYOURTECH3DPthat’s true, but I built my mercury one.1 on a 377 x 377 bed and it prints faster than this, what acceleration are you using?

[@mizz1414]

​@@aaronhambek6362the 2.4 has a flying gantry, a mercury one is a fixed gantry
You can crank the accel to 10k or even more on a 350 2.4, but the ringing will be shit

[@Thomaspm15]

What’s your settings for PETG, I just recently started printing with something other than PLA and at and the 450m/s at 15,000m/s accel don’t seem to be working with any success

[@zzace00]

What are your acceleration values tho?

[@DarkNeutrino_R]

Your accels are way too low to reach 300mm/s That looks like maybe 100mm/s at best 150. To reach 300mm/s on curved object you need solid 20000 accels. Even then it wont do it fully. And yes 20000 accels are reachable on Voron 2.4 350 with a little bit of tuning.

[@mongini1]

plus higher SCV

[@Todestelzer]

700mm/s travel speed and 7000 acceleration is what I use on my Voron 2.4R2 350mm.
More than 7000 and the motors are skipping.

[@DarkNeutrino_R]

@@Todestelzer you have 0 need to do 700mm/s travels. Cause at 7000accels you are not reaching 700mm/s ever. You either need a lighter toolhead to reduce weight or 48V for stepper motors.

[@Todestelzer]

@@DarkNeutrino_R lol
Here is a example of a fast print. 700mm/s travel moves included.

[@Jagjagula]

Are you running the lgx lite?

[@danielgawedzki3425]

That doesn't really look like 1ft/s, is there some undocumented cap for it?

[@Unscientifically]

He probably needs to up the accel, you will never get to 300mm/s if the accel is slow

[@MorKimchi]

what accel?

[@MrZerocool80]

I have the same with 400. What hotend do you use?

[@64-bit63]

Brother our ender 3s can do that

[@MM-oh3zs]

No, it is not 300mm/s. You have awfully low acceleration. First increase it by at least 3x to see real 300mm/s. Nowhere close to even 170mm/s.

[@maxdolski904]

thats not 300 mm^2

[@Adam-cp1dl]

Hate to burst your bubble but that is not 300mm /s looks about 60 or 80

[@ry4nolson]

Hydroponic pods?

[@sugatooth]

Increase your acceleration. Increasing your speed won’t change a thing if your acceleration caps it, it will never reach top speed. It’s also easier to reach top speed with long linear movements instead of short complex movements (bc less accelerations), so try demo with a simple model. From this video you’re probably not going much higher than 100 mm/s, if that

[@BrinkersLab]

That looks like12omm/s on my ender 3 pro with 10k accel.

[@maxdolski904]

cool build though

[@francisnitsch-jones5908]

accel is too low for that to be worth it. I print at 300mm/s easily with 35k accel, that looks a lot quicker than this

[@Todestelzer]

Your travel moves looks slow. Try 700mm/s and 7000 acceleration.
I print PETG slow around 8-10mm^3mm. Didn’t have much success in printing it fast but for ABS I use 25mm^3 flow rate limit.

[@thenextlayer]

This isn't 300mm/s, you're limited by the volumetric flow of PETG... it melts very slowly. Try it with ABS, it'll go twice as fast.

[@BreakpointFun]

I'm doing that on my ender 3
Problem is, i wear out the wheels, you don't have wheels I guess,
Keep the rails lubed up every month, use PTFE precision oil

[@MrdangerJ]

I have a ender 3 that prints at 700mm/s

[@ErMigens]

Más bien no...

[@christhorney]

their is no way thats 300mm/s, my printer looks faster printing 80mm/s, you have something limiting you somewhere still

[@BreakingElegance]

Been trying to get my damn Voron to print fast but my Bambu and K1 max destroy it in speeds

[@aoyisu1653]

its not about the speed, try 60k accel and then well talk

[@parang889]

my ender 1 can print 100mp/h no problem

[@sentlon]

PETG will not let u print faster then 50mm/s to get good qualitt print, so it doesnt make sense to get a fast printer for printing PETG

[@kv9009]

LOL even my slightly modified ender 3 prints faster
