Regarding the #LDOMotors resonance results, there actually is a difference which is easy to overlook as the graphs are dynamically scaled (check the numbers on the left side). At 6:52 the graph shows the peak at 3.0 for the 0.9° motor and 3.3 for the 1.8° motor, or an increase in 10%. At 7:45 the graph shows the peak at 0.975 for the 0.9° stepper and 1.075 for the 1.8° stepper, also showing a 10% increase. Edit: I subscribed and upvoted after posting, hope that isn't filtered out by whatever algorithm is being used for selection. :)

[@jimmieclark8436]

I totally agree, been watching for a while. Keep up the good work!

[@strictnonconformist7369]

I have to agree, the .9 didn’t have any meaningful advantage that could be readily seen. I think that since you’ve got such a well-tuned printer, there wasn’t anything to gain, and I expect that motor is not the limiting factor for quality. For speed, that also as I expected: less frequent steps means more power and thus speed and acceleration.

[@miklschmidt]

Thank you for this! I could've used this video back in early 2021, would've been so much easier to link it rather than arguing with hundreds of people on facebook 😂

[@Justkyrios]

I was really expecting a noticeable different in the Print Quality/VFA test. What's crazy is how close they came in all of the tests expect the Speed/Acceleration tests where the performance gap was massive between the two. #LDOMotors

[@pooyahesabi]

appreciate that bro you did a lot of work for this channel

[@Aesavyx]

I didn't expect such a difference between the #LDOMotors , I don't know why so many people have wanted 0.9 degree motors when the dimensions accuracy improvement is more affected by the filament than the motors

[@admcstabby]

0.9 can solve some problems that 1.8 motors can create depending on the 3D printer and application. Not so much with CoreXY printers but Cartesian, which many people still have and buy. If you're going for speed on a CoreXY then 1.8 hands down. 1.8 motors can handle speeds and still be pretty damn accurate that 0.9 can't (unless you want to drop money your wallet would slap you for). If you're trying to reduce certain problems on a Cartesian 0.9 can help. I have a couple Cartesian printers that have 1.8 motors and I've been happy with, but my AnyCubic Chiron (don't laugh, it was my first printer and I put a lot of blood, sweat and tears into it before moving to CoreXY and I'll never let it go for sentimental purposes) suffered problems no accelerometer, firmware or upgrades could solve. After putting 0.9 motors on both the X and Y (yes, even the Y axis that I've done a lot of weight reduction on) and tweaking I can confidently say 0.9 motors have their purpose, though it may be fading out as more people move to CoreXY and even better designed Cartesian. TL;DR Cartesian printers can benefit from 0.9 motors to solve some issues since speed/acceleration are less of a concern. Speaking of, #LDOMotors I want to thank you for providing quality and affordable NEMA motors!

[@jamespray]

#LDOMotors ! Appreciate the head-to-head testing. I've been getting great results from my 42BYGHM810 0.9's, partly because they have a very low phase inductance of 1.8mH, so my jaw definitely hit the floor to see both of these only have 1.5mH! I think that might be the lowest I've ever seen. The rotor inertia is a little high at 85ish, but I'm not sure how much impact that has. Not surprised by the performance results since they have the same phase inductance, meaning the 0.9 will generate twice the back EMF. You'd have to have a pretty bangin' extrusion solution before either choice became your performance bottleneck at 48V, though! The quality comparison was also interesting - both motors get artifacting in certain speed ranges, just different speed ranges. I expected CoreXY to show more difference, but it seems good motors make more difference for this motion system than the steps per mm. I definitely noticed a difference on my delta going from 1.8 to 0.9, but I also stepped up motor quality in the transition and changed boards from 8 to 32-bit at the same time, so I never got a chance to A/B just the stepper impact. Changing motors would be a pain, but if I win some 1.8 LDO's, I'll totally run a head-to-head!

[@DMonZ1988]

thanks Vez! really glad LDO has established a good reputation and we have more and more distributors of reliable, high performance motors. very useful to have a go to supplier and your tests are really valuable. quite surprising results. for a long time everyone was convinced you absolutely had to have 0.9ers for a corexy, but clearly not. happy that all my older motors aren't disgraceful trash in that regard, even if i can't get the same speeds with them. great work #LDOMOTORS !

[@MatrixRay19]

Gotta love that you chose NEFFEX for the printing compilation. #LDOMOTORS

[@androiduberalles]

I'd be interested to see if the drive pulley tooth count has a major factor on the performance. I'm glad I didn't let people talk me into .9° steppers. I still haven't turned up my super whoppers. Wonder if it could keep up with yours. Probably not 😄

[@NBFL]

[@JamieHarveyJr]

Changing the pulley tooth count will definitely change the performance. Search YT for EddieTheEngineer and his motor torque calculator. It has a value to change the pulley size and see how speed and torque performance changes.

[@henrikgilda4969]

Interesting comparison! I was really surprised that the 0.9deg motor didn't have at least slightly better print quality. But the vase mode and flat walls maybe evened things out too much? Maybe should have printed some other more complex figure that might have given the 0.9 a bit of an edge, like a mini-Simon character? :D #LDOMotors

nice video I really needed something like this myself I compared stepperonline nema 17 1.8 and 0.9 steppers for precision I hooked them up to a linear encoder with high precision run in a range of speeds and finally the 1.8 came as more precise by very little 0.03 if I remember right the excel chart but 0.03 can be a lot depends on the project requirements

#LDOMotors, the high quality 1.8° that have the same vibrations of 0.9° allow the 3d printing fast with high quality. This take the 3d printing to another level. Fantastic!

[@BruGSSantos]

Cool comparison, I was expecting a greater difference on the quality test, maybe the 0.9 would be better showing fine detail. But since both are high quality motors, the high quality prints were expected #LDOmotors

[@admcstabby]

On CoreXY printers 0.9 motors will most likely show little improvement over 1.8 motors. Cartesian printers IMHO can benefit more from 0.9 motors with solving certain issues since speed is less of a concern.

[@CNCTinker]

[@Titan3DAZ]

I absolutely love this. Thank you for doing the comparison of the 2 types of motors. I'd definitely get the 1.8degree motors because higher speed and acceleration is more important to me, especially since it can pretty much keep up on quality anyways. #LDOMotors

[@andrewurban9369]

If you want to improve the performance of the 0.9 deg motor set the micro steps to half of the 1.8 deg motor. This will give you the same resolution for each motor but substantially increase the available torque for the 0.9 deg motor. acceleration will be more than double say from 16 micro steps to 8 microsteps

[@mattschwartz2722]

Thanks for putting in the work Vez! #LDOMotors

Great to see a back-to-back comparison, since swapping to 0.9deg motors (at the same time as swapping board and drivers) I wondered where the change in noise was coming from. Thanks... Looks like some 1.8 #LDOMotors are on the shopping list.

#LDOMOTORS. QUITE EXPECT 0.9 will be noisy, but I expect better quality. Maybe in many detailed printings show his advantages. 1.8 is definitely faster and quieter than I except lower quality, but it depends on what we print and how detailed/quality print we make. Good job!!!

[@1kreature]

Why are you doing this comparison? They have same inductance, same coil resistance with same amps rating and max torque. This means they will build the torque identically and so with the double number of steps pr time unit required for the 0.9deg it will reach the slip point at half the velocity on speed test assuming equal load. For the acceleration it is a bit complex due to the changing direction but same principle applies. The only real question here is if you need the extra steps resolution or not. For belt drive it is often useful.

[@davidwang_3d]

I recently compared the speed and accelerations of the LDO-42STH48-2504AC NEMA 17 motor and the Stepperonline 23HS30-2804S NEMA 23 motor, both 1.8 degree, on a Rat Rig V-Core 3 500. I got the NEMA 23s thinking I can get more speed and accel, but those LDO NEMA 17s outperformed the Stepperonline NEMA 23s. They are truly impressive. #LDOMotors

[@greggobloke32]

Love what you do Vez. Keep up the great content. #LDOMotors

[@neur303]

#ldomotors Yes, If you just change the motors the resonance of the structure will not change. Not an expert but the only thing that could change is the way power is transfered over time. Since steps with the right settings are always completed successfully, only the frequency of the steps and the harmonic content could change, before it is coupled into the belt and the rest of the structure. It seems 1.8 is pretty much the sweet spot for steppers. The rest you could do with gearing if higher resolutions are needed.

[@FlexMoePower]

I know I'm late to the give away. This step off was a good comparison & explanation as well. Keep it up, If I can build a printer half as good and fast I'd be very happy. #LDOmotors

It seems that the last speeds that have been tested are those that do not give vfa, so the "bad" speed is at the bottom, for both motors. In sumary, print as fast as you can and avoid slow printing.

[@Alex-ws5pv]

#LDOMotors Hmm...I expected the 1.8. to be faster than the 0.9 motors, but I'm definitely surprised that the quality is quite similar. I expected less VFA with 0.9, but in your case 1.8 looks also very good. From my point of view is clear that the frame construction is much more important in the appearance of VFA that the stepper motor being 0.9 or 1.8 degree.
