Johniimicro you win the comments

The prints will be too scared to fail

or just use green loctite, that stuff is even sturdier than a certed weld lol

@@SharkyMoto jb weld ?

... yes. And I'd like to know how often you have to buy new rails if you always use these print speed :-)

@@georg_sev genuine hiwin with regular maintainance will last virtually for ever!

People have tried before but not been able to tune them good. We will see how this goes. Odrive has also developed more over the years.

@@Jonas_Aa exactly. Can't wait for the results.

look over to hevort channel, he recently installed some clearpath servos and did a 5 minute benchy...

The cell phone is boosting db gains

Well, you also need a nozzle capable of heating and pushing filament with matching speed... that's the current limitation. Somehow I do not see the point of having super fast xy without non-existing nozzle 😉

@@mehow357 There is a point to it though, and a good one at that. Prints often need a significant amount of time spent with travel moves - other cnc machinery usually has fast rapids to deal with that, often more than twice as fast as this even though they're moving hundreds of pounds and with high acceleration - because it saves a very relevant amount of time per cycle. It's a no brainer to make travel moves as fast as possible, can really save some print time. Besides that, it's future proof and very often comes as a free added bonus with motors that allow high acceleration to print small, highly detailed or infilled parts.

@@heinzhaupthaar5590 I hear you, though consumer 3d printers are a compromise between quality and the cost. It's a no-brainer to just put servos and/or beefier steppers with encoders, more powerful drivers (beefier motors = more power) and call it a day. But then you'll need more efficient heating block and more durable and efficient nozzle. Everything costs money and instead of spending 400-700€, we'll talk about 1500-3000€. As for pure performance and details quality, I'd encourage people to look at resin printers. Yup, you're loosing materials variety (nylon, wood filaments, ect.), but let's be honest - 95% of prints are pla or abs prints, so resin will be super fine. Even though I own Prusa mk3, I'm considering buying resin printer for detailed prints (and keep filament-based for large models or exotic filaments). Even though I would love to have faster printer, I know why it will never be for that money. On the other hand I'm wondering what was the cost of the build/upgrade to achieve that speed.

@@mehow357 That's right, a "race horse printer" can be expensive and just isn't very beneficial for most. I meant it more along the lines of using what you got, ie using your printers max speed for travel moves is a no brainer, yet many seem to neglect this way to save print time although it can shave quite some time, obviously depending on the print. You usually have high speed capability anyway if you try to get really good acceleration values. Especially in that case one should utilize it. Looks amazing as a bonus.

@@heinzhaupthaar5590 you're right and that's how I try to tweak my slicer (among other settings, you have travel speeds & acceleration) 😉 there is one thing though to consider - 3d printers are using bare stepper motors, without encoders, so there is no feedback (3d printer requests to do X steps and just hopes it happened). With aggressive settings sometimes I'm getting failed prints, due to missed steps (that's why in prev post I was mentioning servos or encoders as potential upgrade). But in order to upgrade it that way, I should consider changing the board and software. Also, everything costs and would double the price of the printer. For that money (the cost of the upgrade) you can buy resin printer 🤣 And that's what I'm considering right now for myself 😉

servos are future of 3D printing yes. This Odrive system turns any BLDC into closed loop servo mode with an encoder :) Making it a cheap alternative for servos

@@Vez3D Have you thought about counter balance using the opposite side belt so the force cancel out or at least a bit? For the moving gantry. 🤔🤓

Haha no it will be fine

I dont think they will cooling. They dont even get hot. There is no weight to carry for them

@@Vez3D they'll need a little bit if cooling if it's a heated chamber, but fantastic work on this

Given the implementation time I would say he is almost certainly using step/dir mode with the Odrive board. To use any other mode would require reconfigured software and that takes some time. However, he might be an absolute beast and got it done really quickly.

Who knows, perhaps they can take twice as much or more.

My experience with PID on Odrive is that they can be tuned to behave almost exactly like a stepper motor with effectively no overshoot. (Under a thousandth of rotation is very easy to achieve)

It was temporary for this video. Its been fixed. Its just that i had belt failure 10min before that video and I tried to mount the belts in a way it wouldnt fail for the accell test :)

@@Vez3D ah ok^^ btw, I am a huge fan of your build, constantly checking if you did something on it

I have another HotEnd coming this week that should allow crazy print speed!! ;)

its not going to run at that speed all the time. that was just a demo of their capacities. Also.. do you have a suggestion for idler pulleys ? I was running bearing beforfe (well im still runing them on the smooth side of the belt).. but I have switch to toothed idler

@@Vez3D I planned to use common toothed pulleys (like connected to motors) but with bigger count of teeth (30+) to have the ability to cut holes inside and integrate 12mm O.D. bearings into. Otherwise, when possible pulley may be seated on the shaft which fixed on bearings (but this simpler to implement on h-bot kinematics)

Abs can print quite fast.

Klipper + step/dir

I just received my 100watt yes

Where do you buy it?

they capable of microstepping exact the same way as stepper motors, only difference, to microstep with BLDC you need accurate encoder

i dont know yet

The learning curve. But i will try to document and help people who might want to go the same way. Closed loop is next gen 3d printing

@@Vez3D Nice setup, could you share your setup ? motors ? configuration ? I really would like to use this on my JUBILEE :-) thanks

@@juliendubessy6416 im doing a video about it

Step-dir

@@Vez3D that’s unexpectedly good looking now, I’ve researched kinda month or two ago and only find out huge amount of concerns about step/dir since odrive does not know “whole” motion and cannot plan accordingly, good to know that it can be used this way with not that bad results

They have for 3d printer motion. I cant move it with my hand

We shall see soon

Odrive is a really great system and very affordable so I imagine that is why he chose that over other servos. Besides it makes sense to go ahead and get the extra torque.

I would have gone in that direction too. The hobby brushless motors are designed to be used on planes and drones with a torrent of air cooling them. I can't wait to see how fast it ends up running, though.

X and Y don't need much holding torque

Its way more than I thought. You cant move them by hand.

It's going to vibrate regardless, it's belt driven.

@@timmturner Yeah I know but he's already got it anchored to fight vibrations, just making the case here that perhaps more anchoring is in order.

@@KyleJohnsonVA what I mean is no matter how much anchoring you do there will still be resonance

@@KyleJohnsonVA Can you flip the whole printer upside down so the moving parts are at the bottom? I saw Maker's Muse do this.

Lol 😂 don’t you know as soon as you buy something it’s outdated. I feel that though. As soon as I bought my thx 980 the ti launched a month later. I was so mad lol

servos (good servos) are expensive.. .thats why.

@@Vez3D 1k bucks for 3 axis - not so expensive.

@@101picofarad well we dont have the same meaning for expensive haha

@@Vez3D simple i calk my time to reach result :)

I mean there is always the supervolcano

i was just thinking, if you preheated high enough, then that wouldnt matter much for the benchy race, if the heater cant sustain a certain temp, might be an advantage to drop temp for the funnel actually?

Yes.. again I went to bed late haha. But printer is back. And it will be stronger now. I use the odrive board v3.6 56V

Yes. I had a snap that day.. and I hooked the belts like that temporarily to make the video only. Good catch

man im having so much fun with all the plots graph and data I can find. And in the video, it was only pulling like 2-3 amps from the PSU ... they are not even sweating

@@Vez3D Omg I want a ringing/ghosting test please

odrive controller

Check some of the other videos What you see at the start of this video is going to be print speed

who said they were not closed loop ;) Indeed they are.. with a 8192 CPR encoder.

@@Vez3D Ah, ha! That’s awesome. The only one problem remains: the motion is so fast it’s blurred. You need a faster shutter speed (more light)! LOL

Its overkill and thats why I love it :p

odriverobotics.com

Do you buy only the motors or also all the controller etc?

@@th3ar216 you need motors, controllers, encoders

@@Vez3D what encoder and controller do you use ? 🤔

@@th3ar216 the one they sell on their site

I cant say. I have not tested clearpath. But my buddy Oliver from Hevort is testing them now. Beast mode!! But for 1k$.... odrive is much cheaper

@@Vez3D I like that you can try diff motors to which ones did you go with ? And I am thinking that we can use canbus to control it with the canbus hat that we use for the klipper toolboards

@@advanced3dprinting i used the 270kv ones. The lower the kv the better for our printers i think. Also i used the step/dir mode using the 3d printer mcu driver pins to connect to odrive. The canbus was also an idea I had but Im affraid it might be limited with bandwidth

@@Vez3D i already tested that at the beginning of odrive history, but I have some cogging torque at low speed, do you have the same issue ?

@@Schointss at very very low spee yes
