i was surprised when i saw that you have less than 100 subs while watching the video, this is some 1-mill+ production quality

Keep cracking bro, very well made content. Only a matter of time before you grow

Cycloidal drives are pretty cool

How do you have such little subscribers for the high quality content you produce? Its really good its educational and funny! ^^

thats crazy that someone with 83 subscribers has helped me so much more than any other channel or video ive seen. Thank you so much! keep up the good work!!

Great design!! Keep up the good work!! Great content!! 😊

This is great

44 abos, that cant be real, great video !

Would say this is a very good summerize for me as what tricks and pitfalls are in making it.

Nice one

I was designing a cheap cycloidal drive as well, very similar to yours just slightly smaller with very few bearings and no low friction materials, your efficiency numbers are very similar to mine (around 27%), I think that's about the limit of capability for a design that minimizes bearings and is mostly made out of 3d printed parts so I think the design is good, it's just reaching the limit of the materials and techniques used, I am yet to try lubricating the cycloid, but I don't expect it to be a huge improvement.

Nice design. Did you measure the torque of just the stepper motor? Your efficiency should be closer to 75%.

Really cool dude, nice video and fun project

the only issue its off-axis, not centered, try tesla turbine air friction gears instead. can be made in on axle, but also just like normal gears.

I wonder how small you can make it, and then I wonder how well that would work in a 3d printer extruder with that high gear ratio! Has a lot of new designs are using planetary and other designs to generate high gear ratios to allow the stepper motors to turn at their optimal speed

I feel your pain, ive deisgned many 3d printed cycloidal gearboxes and the efficiency is just terrible. Im currently working on making my own almost fully metal cycloidal drive and im expecting some huge imprivemnt, maybe gonna make some video about the difference, but first i got to learn how to use lathe properly... have fun on your future projects.

138 subs is criminally low

Love this video and your whole style. I think you might be able to get much closer to your 40Nm target if you use some kind of code to smooth out the stepper acceleration. Maybe because its trying to lurch too much the motor driver current tops out or some shit? Maybe you've already done that and its just the way she goes with too much friction in the gear box though.
