Leversofpower's Un2003a 28Byj48 Stepper Motor Project
This is a tutorial for implementing UN2003A 28BYJ48 stepper motor controller combo. This motor stepper controller combo...
Igor's Robot Guard
Bhouston's Rubik's Cube Solving Robot
I found this robot on Thingiverse; www.thingiverse.com/thing:2471044 and thought it would be a fun project. Check it out...
Please do so, I am currently working on a two stage cycloidal gearbox...and am hoping that the centered mass of the offset disks will be reducing the vibration!
A planetary gearbox is also something I am conidering...I had the feeling that it would produce too much backlash, but that should also be possible to get sorted out!!
Sorry for hijacking this thread, lets start a new one!!
OMG, I am such a noob...just blew up a power supply!!!
The magic blue smoke had not happened for a long time...these drone motors draw a crazy current!!
@Mickey666Maus Sorry to hear about your power Supply. Talking about gears My inmoov Brucee is using a planetory gear on his elbow joints. it is powered only by an ez-robot HD standard servo, lifting all that weight. and it is not that slow. I originally printed the gears using PETG but there was a bit of flex between the four center gears and the outer gear causing slippage because of the large amount of weight from the arm. PLA filament developed cracking. ABS to much flex. the best is carbon graphite filled nylon very tough and easier to print then standard nylon no warping or shrinking that regular nylon does, and it is self lubricating.
@mickey oh no! What happened??????
Hahahaha, I really don't know...but I guess you should not use 1.5Amp psup for a motor that can draw 14Amp easy!! :,D
Hahahaha yeah that might be your problem.
@nallycat that filament you are talking about sounds great...I would really like to check it to, I am always printing in ABS...I never noticed it had that much flex!! Good point!!
I actually always wondered, how you guys are managing to move all that weight of the Inmoovs with standard servos...would be fun to open a thread concerning all those issues! Like good printable gearboxes, different types of filament and motors!!
The Cycloid Gearbox does have issues with vibration...I will try to put a little demo together soon!!
Here is a picture of Bruce-e elbow this is showing PET-G as it is white and I it is now Black, I didn't take a new picture, you can see the EZ_Robot HD standard servo and the planetory gear is the top gear The nylon carbon fibre filament I get it from SPOOL3D but I understand nylonX is also very good, you have to use hard steel or a ruby nozzle on you printer as this stuff is very abrasive. I also use .6 instead of .4 nozzles.
