I’d call this the absolute beast! Very well done Mr. Vez - tech power and appealing 🤩🤩🤩
At those speeds the print head almost looks like it teleports from one side to the other! Blink and you'll miss it! Great work Vez!
Macros have been uploaded to Github. Be VERY carefull with them. github.com/VzBoT3D/VzBoT-Vz235/tree/main/Firmware/Macros
Are you still using Klipper? What is the web interface?
@@billclark5943 yes..its mainsail
Maaaan! THIS video is awesome!
This was something I really was waiting for sooo long!
You're just awesome!
Thanks for showing the possibilities so many of us are reaching for!
Also thanks for all the explanations!
Love your channel and the work your doing. You inspire me!
I was sitting with open mouth in front of my PC not believing what I was seeing. Just wow!
And more thrilling than every modern Hollywood movie!
Insane how smooth it sounds on the accel Test
Fantastic! It's great to see this working!
That’s insane man congratulation man I got to see what you can prints at those speed.
@Vex3D I’m looking forward to the under 3 minute benchy! 🤣🤣🤣
This is just nuts.
With such high G-forces, I do wonder if you’ll shake the extruder/hotend into pieces with them flying about. This will be a great test of long-term material fatigue at over 10g acceleration/deceleration possible,
WOW a really fabulous job. I have been following the whole build with great interest and I must admit that they are stratospheric numbers. I think now you need an extruder that keeps up with your hotend, which sure can handle these speeds.
that VzHextruder is perfect for that.. I reached 130mm3/s with it and the LSD60... so maybe close 90 with this LSD54 ? we will see
@@Vez3D I just noticed how big the extruder motor is... may I ask you what motor is it? my god, 130mm3/s is a lot
@@michelesoldi9177 LDO nema14 ..20mm version running at 0.6amp
@@Vez3D mmm, then that's what bondtech also delivers with their LGX lite extruders. At this point I think I have a problem with my volcano hotend 🤦♂
@@michelesoldi9177 the extrudor is very capable..its always the hotend that is the show stopper
Looks amazing. Subbed
Incredible!!!
Ah yes I do apologize. I missed this video. That's awesome!
The laugh is so evil haha I love it .. well done
Insane! 😳👏🏻
the best part of this video are the giggles and chuckles.
good job my friend👍👍👍
Wow! it's a fast Incredible monster!
That is awesome! Best printers ever (330, 235).
That's craaaazy!
Amazing.
pretty interesting, with closed loop nema 23s the weak point is the belts I get belt skip/rip before a motor will fail lol
Holy f*cking shit! And i thought I had a fast printer! Lol
This video is the equivalent of Goku going Super Saiyan 3.
>Vz235: *goes 30,000 accel* This is my normal Speed form.
>Vz235: *goes 50,000 accel* This is my super speed form, or Super Speeyan
>Vz235: *goes 70,000 accel* This is my brother 330's ultimate speed form, or Ascended Super Speeyan 2.
>Vz235: AND THIS *goes 100,000 accel* IS TO GO EVEN FURTHER BEYOND!
>Vz235: AAAAAAAAAAAH *attaining speeds beyond 120,000 accel* AAAAAAAAAAAAAAAAAAAAAAAaaah... and this... is Super Speeyan 235.
Now you only need a montage for ultra instinct Vzbot, and you are golden.
I wonder if it’s possible to get over 100K acceleration on a larger printer.
I wonder if you’d be able to do a speed Benchy in under 3 minutes.
Edit: also, do 0.4mm CHT nozzles have the same maximum low limitations normal nozzles have?
they have higher limitation, but its not super high either
I don't think it will be able to reach 2000mm/s speed while printing. It will get close possibly around 1800 but I'm definitely super excited to see the results either way. I am hoping for the 2000mm/s and some half decent quality finish would be even sicker
yeah i think its more important to get higher acceleration/deceleration
Nice work!... I wonder what speed you can do a quality print at?
Nice!!!
Any reason you don't use the WC hextrudort?
100K using the 80% rule for regular prints is closer everyday looks great excellent job does it come in a box yet? or even the LSD?
Will there be another #SpeedBoatRace / SpeedBenchy Attempt anytime soon? I’m curious how this can do record wise!
Its a monster ;)
Nicely done vez, extremely impressive.
It hurts to correct you, but when the printhead moves in y only 2 motors apply torque, not 4, although 4 turn. The two responsible for a straight x movement are not applying any force on the y gantry directly (if you undo the y belt and do a x move the gantry will slightly move due to inertia of the printhead), the only overcome friction and internal stresses in the belt. But you are right about the weakest point, a 45° movement, the y motors need to accelerate the gantry and printhead in y as well as the printhead in x. Tje weakest link speed wise is a 45° movement were the x motors need to turn twice the speed of a linear y movement (45° x motor doesnt turn, 90° x motor turns at V speed and at 135° it turms at 2V speed). I hope that doesnt confuse you, i was quite surprised that many youtubers claim that you have the force of 2 (4 in the vz235's case) motor for a y movement, but in reality 1 applies its force and the other one executes a correctional movement. On the other hand no paper claims that all motors apply their force for a y movement. But some said youtubers also say that the ender 5 is a core xy, which is BS.
I hope i brought some clarity into this topic and didnt cause some more confusing in the world of 3d printers
Im not sure here buddy. When you go in y or x.. both corexy motors will run together...and on a quadxy..its 4 of them. Unless im completely sniffing glue here
If you remove one belt .. it will move in diagonal
Both Motors Move Clockwise >> Carriage Moves Left
Both Motors Move Counter Clockwise>> Carriage Moves Right
Both Motors Move Opposite of Each Other>> Carriage Moves Toward & Away
One Motor Moves>> Carriage Moves Diagonal
@@Vez3D yes moving and applying torque are two separate things. As i said, on a y movement both x motors basically apply no torqueon the gantry, only the y motors move the gantry plus printhead while the x motors make sure the printhead stays where it is on a linear y movement. Since the is no velocity change in x, the x motors are just overcoming friction.
@@Vez3D ah, sorry bud, hadn't the core xy kinematics completely in my head, was thinking of a hybrid corexy or something like that where thy y belt is only attached to the gantry and not printhead
You can delete my comment if you want :)
Judging by the width of the X and Y axis, I think you can use larger belts. Maybe that would help ?
Very nice build...
If you would build your first Vzbot... which size would you prefer, 235 or 330?
Would like to test those macros but i cannot configure them. My present machine (sapphire pro) cannot exceed 2000mm/s without constant layer shift. So it would be helpful to test macros and adjust things to figure put what is it that limits my acceleration and deceleration
DAYUMN!!! 😃
At what point do you have to start using special pulley bearings so they don't explode from heat? 😅
Have you checked out the Leadshine 42CM06 stepper motors? They have lower resistance, inductance, and rotor inertia compared to the LDO 42STH48-2504AC while having more torque. They may be able to do 2000mm/s @ 50K acceleration.
Ill look them up :) ty
I'm kinda curious if having the quad motors will help cancel out some VFA from the motor resonances.
I tend to believe yes. Because less belt backlash too
129000 ACCELL??!?! BONKERS!!
Seriously, super impressive!
Ive got a question regarding your cooling... and im wondering if i just somehow (but seriously unlikely, as i stated in another comment recently, your one of the very few i follow religiously, lol!) missed the vid on it, BUT -> the CPAP cool er air pipe.
What exactly are you using to actually pump the air TO the part cooler??
a cpap fan
Isn't that tubing dragging a lot across the top panel? Will it interfere with input shaper?
nah I dont think so. It doesnt generate any vibration
In the last video (electrical) you were saying you would show how to install the software side of things. Is there another video where you have shown this before?
Not yet done it...been on vacation
👌👌👏👏💪💪
12.7G of accel wow… just crazy. Now just to make a hotend that Can keep up lol well done!
The cheap rail probably didnt have a true Gothic Arch for the bearings to ride in
Wow
How do you know the motors are running at 2 amps? Do you have an ammeter connected in series with the motor to check?
Its a setting in klipper.
youre using a separate stepper driver for each 4 motor right?
Yes
wow thats a nice build m8 where could i buy one ie kit same as yours any idea ie the whole thing upgrades every thing ? as right ow iv a tevo tarantula its been fun works well just slowwwww
After chinese new year we will have full kits available on aliexpress .. mellow store
Have you thought of changing the motors to bigger ones or more powerful? That could be a way of getting the super high acceleration with high speed.
Maybe 4Amp or higher?
Yeah I did try many motors. Bigger isnt always better...as more mass / inertia and more vibrations. I enven tried servos..bldc..odrive
Is this aluminium rod gantry better than carbon fibre rod gantry.
did you hear about the Bambu Lab X1 Carbon?
Of course :) very nice printer
Did you accidently do the xy acceleration test at 2500mm/s? In the video you say you are doing it at 1000mm/s, but the velocity shows 2500.
Nah.. 1000mms. The 2500 you see on the screenshot is the max speed set in the firmware
@@Vez3D thank you
Go BIG or go home, right boys?!?! hahahah!!

How fast can you print benchy?
the reason your mgn 7 rail is flexing so much is because your rail is on top , and all that weight on the bottom means the center of mass isn't right on the rail, so the rail needs to bear both thrust and moment, casing it to bend and twist, try placing the center of mass of the entire print head right on the rail block and give the mgn7 rail another try
Most of the weight is already on top..with the extruder.
also.. without any weight on it.. just the aluminum top plate.. .its definately flexing way more than a MNG9.. so .,.
What is the max RPM you use at 2000mm/s on the motor? if i may ask?
With 20t pulleys its 40mm per rotation.. so 50 turns pers sec.. which is 3000 rpm
fast microplastics
does anyone know the final price of this build ?
If you're okay with adding two more motors you can remove all the weight of the direct drive extruder motor and still have it be direct drive
?? I must admit im not understanding you here :) please to dumb Vez
How do you level your bed?
Do you have a part # / link for the Hiwin rails?
I bought it from Spool3d.ca . .however they only 450mm in stock..so I had to cut it to 300
@@Vez3D Are you in Canada?
@@fish3dp372 yes
@@Vez3D Same
How much has this machine cost you? I’m interested in building one
Hard to say because i took some parts from my old voron 1.5... then some other parts i had already..and some other parts were given to me from my partners like Mellow and F3D
Probably the most made comment but, for those looking to clone this, what is a total cost? (Prices aren't listed on the BOM?)
its very hard to say.. it depends on the hotend, extruder, electronics etc.. but rougly 1200$ and it go up depending on all components you chose..and the price of pannels in your region etc..
So your mgn 7 rail was bad
?
Rail was good for a mgn7. But being mgn7 was not stiff enough
mmmm Give us that Macro 😁
Ok i will
its been added in description and pinned comment
Speed means nothing when there is no filament that can be printed at these speeds!
very true ;)
Nice Video but you use too many engery for FDM Printer, because too many mechanical elements, that is not the future. The speed and quality will limited by the mechanical elements
Hi sir. Any suggestion? Please show me what you have in mind that is the future :)
@@Vez3D i think resin is the future, faster, better print quality but the prints not stability and the print material is not good at this moment.
It won't print at 2000 mm/s. Layers wouldn't adhere and lines will tear. I tried with my experimental ODrive-based printer and PETG filament.
But such travel speed might make retracion useless. :)
I was able to print at 1500mms.. so maybe :) I have better flow now with this hotend so we shall see
That text flash is too fast at 7:15-16
it was a render issue.. the message says the video is not available or something.. but it rendered anyway.. weird bug
@@Vez3D Only after watching the whole video did I see happen through that segment. Wasn't sure if you were pulling a Tyler Durden 😄
only thing (because im a pedant apparently), MGN not MGM, MGN is Miniature guiderail narrow, MGM is Metro-Goldwyn-Mayer (the film studio)
?? of course its MGN... did my pronounciation sound bad ? :P I know its MGN dont worry :) if I pronounced it bad sorry..
@@Vez3D it might have been my ears, but the N sounded like a second M, no need to worry. this machine is an absolute beast though. i loved the initial test of cranking it till the motors stalled to see your accell ceiling
yeah you are right.. listening to myself again, and I do think I sound like M instead of N :P sorry for that
