Love your videos! Super interested to see the Odrive. If you are able can you film parts of the next video in slow motion? The print head was already a blur in this video 😂
Great info! I have seen some torque charts for the 60mm LDOs and I think they can still perform if they are geared up a bit, say, with 25T pulleys. I’m testing out OMCs 48mm 2 amp 1.8 - I have been told it’s a cut above the rest as far as torque.
Yeesssss I thought about that last night haha! Some brushless Motors with that special controll board for super high speeds, accuracy and acceleration!!! I am stoked to see the results haha
I am developing my own printer right now. If I had more money I would completely redesign my printer lol. But I figured I can build another printer at the end of this year with the focus on super fast speed and maybe tool changing. One idea I had were those brushless motors!
Mark Rehorst did some good testing of closed loop servos motors on his 3D printer on his blog. Comparing his findings with your O-Drive experiments will be very interesting. Thanks!
SUBBED FOR THE O-DRIVE OMG OMG OMG!!!!!!!!!!!!! This has got to be one of the coolest 3-d printing projects around! Now all you need is automated head changing for blazingly fast multi-material prints

@@Vez3D this one is good. But actually yours is much better because you have a much simpler designed printer, which is much better. And you provide a ton of necessary Infos to build really fast printers.

The Hevort is a good recommendation but waaayy too overengineered at a lot of points where your printed just shines with a much simpler design. And a simple design is the real challenge for a good engineer. I really prefer yours over every printer I've seen since I'm in 3d printing.
Great job! I have the same experience with those steppers, I could run the LDO at higher % of current than the e3d but at the same % of current it got much hotter.
I like that you've pumped up the video: those intro/outro, b-rolls and music - really pushes your clips to the next level of quality! Can't wait until you open a Patreon page $)
Thank you for telling me the result in the first place, i bought the E3D steppers on your recommendation, but still enjoyed every second of this video. And please, dont break your machine in half with these steppers, theyre BEEFY as hell ! :D
Dont try it. The iHSVs have a peculiarity in their construction that make it difficult to make perfectly smooth walls when using belts as it is in 3D machines, I do not recommend them. Better good stepper and good driver than cheap servo.
Thx for sharing such a great video for product comparison!!! My coreXY machine with 70nm torque steppers as X+Y motors stills having layer shift issue sometimes whenever the speed up to 250mm/s or above. Do u think the shape of my machine in rectangular with 550mmx350mm printable area is the root cause? Or coreXY must be in “square” in order to keep all belt tension in even? I am using 6mm belts for X/Y btw. Thx!
Hey Vez, love your videos and content :-) just wondered: why have you opted to use LDO motors on your printers when you show here that the E3D ones were better? Did I miss something?
Link to the specs sheet/ part for the tested parts in the description please. I have the nema 17 48mm 0.9° stepperonline motors for my build. There are others all ready using these like the 4 stepper motor hevort that was made. They have some promising results but i think your next best bet is to find amazing nema 23 motors.
Did You try to test those steppers with other drivers? this may bring other results - also as the board You use has the option to replace drives - external higher voltage drivers may give even better results...
This video could not have better timing. I'm in the process of building my own CoreXY and sourcing LDO motors in the UK is very difficult. Question: how about noise? I understand you're running at 40k accel but at lower speeds, let's say 3000mm/s² and 100mm/s, is one motors significantly louder? And how about VFA reduction? Great video :)
How you compensate for higher inductance is by increasing the voltage. Field oriented control also helps significantly. As long as you have the proper power stages to handle higher voltages, go ahead and add a 96VDC power supply and see what kind of a difference that makes.
I appreciate those high speed/acceleration videos, but can you pls make a video about dimensional accuracy. Is this still a thing when it comes to these high speeds/accerlation?
My printer is being uograded at the momment but I can say that its been fine for dimensions so far...on simple to moderate complex part. For really complex and small details part.. you need to tune your slicer at lower speed on some places.
LDO has a high temperature version of same motor so would be interesting to know what was % difference from the e3d high torque. E3d doesn't offer high temperature version
odrive yay! I wonder how the precisions will be as this will surely need a bit of fine tuning on the PID controller depending on the aimed acceleration... Also at what point of the accuracy gcode will move to the next line? I think there should be a threshold accuracy value needa to be implemented, yeah? Cheers for the video and the comparison!!
it maybe the higher mass of the rotor is not able to be so responsive at these higher accelerations, it may be another story if your hotend and moving parts were heavier. I also noticed LDO didn't list the detent torque which has a larger effect at such high accelerations. loving the work on brushless motors, tuning them should be a learning curve , with respect to extrusion rates. best of luck!
Vez i have one question for you. I just got my high torque based on your recommendation. I just found out that they have a smooth shaft, not a v cut. Did you mount the pulleys in any special way? I'm worried about them slipping. Thank you
Hmm, I have to say that I didn't see that one coming. I would've bet on the 60 mm anytime. I guess there's more to speed and acceleration than inductance and stall torque. Can't wait to see what you can do with those brush less!
I'd be interested in seeing a noise comparison between stealthchop and the odrive, I've been thinking about making a small printer with a focus on quiet operation.
if you replace all the fans you can make a ender 3 v2 very quiet... the hard part is decent 5015 blower fans, i dont know if they exist :( . but all the others are easy go big pc fan for motherboard and psu, 4020mm fan for hot end... im sure you can do the same with many other 3d printers...
hey buddy did you try these results with 5m pulley and belts. On RepRap emf calculator page that will eventually increase the speed by lowering the steps when you use 5m pulley. Do you think that will help
Would the microstepping ratio have an effect on the maximum speed/acceleration? Microstepping brings the effective torque down drastically right? what microstepping ratio are you using?
Should these numbers of acceleration and decerebration keep equal? Since Deceleration is actually acceleration in an opposite direction. So 40K accel.+ 20K decel. is actually = 30K accel. 30K decel. limit? Or I'm I missing somethin ? Or should it be 40K accel = 20K deceleration to fight opposite momentum of the moving mass?
the deceleration setting isn't deceleration.. it's a speed limiter and don't alter the deceleration or acceleration in any way. here's how Kevin explain it: Specifically, the code calculates what the velocity of each move would be if it were limited to this virtual "acceleration to deceleration" rate (half the normal acceleration rate by default). In the above picture the dashed gray lines represent this virtual acceleration rate for the first move. If a move can not reach its full cruising speed using this virtual acceleration rate then its top speed is reduced to the maximum speed it could obtain at this virtual acceleration rate. For most moves the limit will be at or above the move's existing limits and no change in behavior is induced. For short zigzag moves, however, this limit reduces the top speed. Note that it does not change the actual acceleration within the move - the move continues to use the normal acceleration scheme up to its adjusted top-speed.
I'd be curious to see you redo the test with 25T pulleys instead of 20T. The higher torque would work better with 25T, which would also give it higher speed. 25T also works out to an even step, so it's a "clean" number.
Hey, did you test both motors with the same current? Presumably the LDO motor could handle more current with the larger size? I wonder if it would perform better with more current.
Epic! Couple of questions: - Do 0.9 steppers sound louder comparing to 1.8? For me the noise much more high pitched during normal speed operations at stealthchop, at least at 24V, comparing to 1.8 steppers. - Have you tried smallest Nema23 steppers instead of Nema17?
It depends on the motor i guess. They are not quiet but higher voltage helps. At low sleed they are quiet though and in stealthchop they are super quiet
Have compared random other Chinese motor with same spec and size. I always suspect that only branding difference in them. I don't own any fancy motor motor but it's seems to me when they say high temperature it's only PTFE wire they use or anything more.
Hi and again congratulations for your videos and your printer. I have a question for you: I made a replica of your printer and work really fine but, if I try with 400mm/s speed and more than 15k acceleration, this cause issue and bed movements. I ask you: do you think the limit is the stepper motor? I mean, do you think that changing motors i'll can go with faster acceleration? I use skr1.4 turbo board with tmc2209 (all at 24V) but standard stepper motors. Thank you in advance for your kind reply. Francesco from italy.
Hey, for your interest: E3D motors are manufactured by LDO. Edit: Jason from LDO did following statement: "Current only Hemera motor from LDO, and may some future E3D project. Their regular stock motor not from LDO."
@@Vez3D Yes, you can also ask Jason from LDO on Twitter. That means that you tested two motors with different specifications instead of two different brands. Nice printer btw!
The E3D motor shown here is branded "MOTECH" (as are all of my E3D motors, and the spec sheets on E3D's website). So is Motech a sub-brand of LDO, or a parent company of LDO? Or something else..? 🤔
Hey, small update, got the info from Jason from LDO: "Current only Hemera motor from LDO, and may some future E3D project. Their regular stock motor not from LDO."
@@Vez3D Ah was thinking where I had this from ( docs.vorondesign.com/community/howto/120decibell/calculating_driver_current.html ) the voron guys again. Don´t know where he got that 1,2 amps from but maybe wouldn´t hurt to try with 5160 trinamic . They can handle more amps (for sure)
The smaller motor does better on acceleration because of rotor inertia and BEMF constants. If you want to increase your acceleration capability on any motor, just increase your supply voltage so that the voltage ratio between your supply and the bemf generated by the motor is above 5:1. The test you've presented is good for showing the differences, but is not good to compare motor capability and saying which motor is better.
Agreed. But we can say that at same voltage the e3d is better for speed and accel in MY setup with that amount of weight to carry etc.. Overall better ? I cant tell :)
@@Vez3D The torque is only required at acc and decc so it doesn’t matter at constant or holding speed without movement. My experience with the same two steppers is the same on my 500x500 toolchanger. My speedrun est was with the LDO and I get much better with e3d now but I have to stiffen my frame before the next test.
What's the reason to compare 2 different tall motor? if you want to do a fair comparation, how about to compare same tall motor, LDO 48mm 0.9 will be LDO-42STH48-1684MAC.
Hello again I'm waiting for your kind answer... In the meantime I bought the stepper in your video (e3d) and gave them 1.2A in the firmware... but same problem. If I go over 13000mm/s acceleration, even at 300mm/s speed, i hear that bed sound and the stepper stop working... Can you help me? Thanks
@@Vez3Dhello and thank you very much. im using extrudort (great project) and same stepper as your for the extruder... maybe to much tension of the belt X & Y?
@@Vez3D I'm on 24V and the project is like your fusion360 project files. The 2020 square tube on X is aluminium not carbon... but super light aluminium (totally empty inside)
When you want speed you can try to get hands on an encoder for those stepper and than use the tmc5160 for them. The tmc5160 is allways trying to get the most speed and with the encoder is the best.

There is more than just torque curve :)
The smaller motor does better on acceleration because of rotor inertia and BEMF constants. If you want to increase your acceleration capability on any motor, just increase your supply voltage so that the voltage ratio between your supply and the bemf generated by the motor is above 5:1. The test you've presented is good for showing the differences, but is not good to compare motor capability and saying which motor is better.
Agreed. But we can say that at same voltage the e3d is better for speed and accel in MY setup with that amount of weight to carry etc.. Overall better ? I cant tell :)
The LDO would be better in another type of test...like moving more mass ... since it has more torque.etc.. :)
@@Vez3D The torque is only required at acc and decc so it doesn’t matter at constant or holding speed without movement. My experience with the same two steppers is the same on my 500x500 toolchanger. My speedrun est was with the LDO and I get much better with e3d now but I have to stiffen my frame before the next test.
With different gearing..maybe the ldo would give more ? So much things to test lol
All I wanna know is how to stop VFAs on my Ender 3 v2 D:
What's the reason to compare 2 different tall motor? if you want to do a fair comparation, how about to compare same tall motor, LDO 48mm 0.9 will be LDO-42STH48-1684MAC.
I would love to :) the reason is that it was just the 2 0.9 degree motors i was easily able to get
@@Vez3D Timing to send you more motors!
@@ldomotorsjason3488 would love to test your best accel/speed beast :)
I already run with LDO nema14 on the extruder and its a small pack of power. Really impressive
@@Vez3D if you email me your shipping address jason@ldomotors.com, I could mange to send you some motors for play and testing.
Are there advantages of 0.9 versus 1.8?
Precision. The number of steps are double.
1:14 OMG
Hello again
I'm waiting for your kind answer...
In the meantime I bought the stepper in your video (e3d) and gave them 1.2A in the firmware... but same problem.
If I go over 13000mm/s acceleration, even at 300mm/s speed, i hear that bed sound and the stepper stop working... Can you help me? Thanks
Your printer must be heavy. Thats all I can think of. Remove weight. Weight is enemy of accel
@@Vez3Dhello and thank you very much. im using extrudort (great project) and same stepper as your for the extruder... maybe to much tension of the belt X & Y?
@@frfioron with carbon tube? And all other vzbot carriage?
Oh.. are you on 12v? If so...there is your issue
@@Vez3D I'm on 24V and the project is like your fusion360 project files. The 2020 square tube on X is aluminium not carbon... but super light aluminium (totally empty inside)
When you want speed you can try to get hands on an encoder for those stepper and than use the tmc5160 for them. The tmc5160 is allways trying to get the most speed and with the encoder is the best.
interesting. I would think you would need some gear reduction for what is coming..
Try sigma7 yaskawas they might pull the printer out of the printer..
That doesnt look like a cheap option haha
@@Vez3D :) I wonder what would be the smallers motor you could use with such servo driver. But indeed.. thousand$.
Are you gonna use O-drives? Won't the crazy performance of the gantry far outperform the ability of any hot end or is this just flexing😂🤔
My hotend with a 0.3 nozzle can do crazy speed :) but the new magnum+ might be in the list soon
I heard that 0.9 degree motor is noisy than 1.8degree motor. Is that right?
what about a diverrent motor styl like servos
This is kinda like a servo..but less expensive
brushless LUL
