Fun fact. It will auto release if you put ur printer upside down. It can fall into a bucket / crate under the printer

Oh my God, I fucking love you. This is exactly what I've been racking my head trying to figure out for the last month, exactly with the brushless motor, simple foc, as5600, 3D printed design, deciding to not use roller pins any more, the fucking black colour scheme, etc. I love you man

I have the O3 and just keep getting this error: 1 [2024/11/05 21:04:18] Connect overtime, try baud rate: 9600 2 [2024/11/05 21:04:19] <ERROR> USB-CAN module configuration failed, please check physical device! I have tried swapping can high and low wires, unplugging usbc etc. I was able to get it connected once but now it wont connect at all, any ideas?

@gerokatseros Ай бұрын

wonderful walk through the steps my friend. The only thing i don't understand is why go through virtual machine just to send serial messages to a com port. I just ordered the same motor. It actually went 42 dollars up in price :) .... propably they realized that they made it famous up to a point with the cheap price and now slowly they will follow the ordinal prices. I am looking forward to see your next videos and more demos on running this motor.

@kindaovermyhead Ай бұрын

The program is really bad to be honest, i’m surprised it’s running at this speed. it can be improved- it’s xrealsdk->unity->flask server->python->serial library for the servos

@pixiepaws99 Ай бұрын

This is just a CAN bus geared servo. Nothing special here... The gain looks a bit low and its position holding looks really bad (by CNC machine servo standards anyway) so you need to adjust the PID parameters.

@kindaovermyhead Ай бұрын

yeah the pid tuning is my own and not great yet, i’ll find out soon if it’s special or too good to be true

so did you make any more checks? does the actuator actually handle 120Nm or near this value? What commands are supported throught the can bus?

the commands are available in the docs on their site, and i’ll find out soon if it’s capable but gotta improve my setup first cause..safety :)

what power supply did you use? also how did you make a joint to both sides of the motor? I am impressed with the video

Seems like a great motor, but $300 is awfully expensive, given you'd need like 4 of them for a humanoid, if not more. What do you plan to use this for?

@TheBozn Ай бұрын

idk at what voltage you ran it but of course you cant hold 120Nm or even 12Nm with that 2 cm leverage... you are trying to counter equivalent to over 1000 pounds with your fingers there.. Itd probably be impossible for you to do even with a normal sized wrench(30cm). Cool motor tho. I would love to see the gearing and more of the inside. I wonder if its just one set of planetaries or multiple and what kind of machining and material quality its for that price. Sometimes chinazon really delivers

May know this already: * Rated current on actuator is peak phase current (which is not related to supply current unless at peak rated speed of motor at 48V, which is kinda unachievable) * Therefore your supply should handle peak torque (even at 30V) at low velocity, so just dial down those gains. * Your supply may have cut out due to an over voltage event due to BEMF generation during backdriving of the actuator (not an issue so mych with battery powered) * To handle these BEMF event your need a "regen shunt" (check o-drive for that) * The BEMF exhiibits itself on the voltage bus by exceeding the voltage setpoint of the supply. * You'll note when the weight is being lowered, due to the potential energy of the lifted mass, the current in the supply should drop ~0amps at times. * the above is predominantly just a warning so not to blow the control board or other devices connected to the voltage bus if they're not able to handle the transients and over voltage events. * testing at 24v, and getting a baseline of behaviour is safer, you have a much higher chance of damaging the controller when running at max operating voltage and then having a large Regen event (backdrive)

@@ZedDead-n3s Sir, i face the same problem ... when my motor accelerates with some weight on it, and i want it to stop in a specifiv position , it shuts down when it is supposed to stop. I was thinking that there is reverse voltage that with the one added from the one that comes into the motor results in low voltage so the motor shuts down. In the odrive they give you a breaking resistor. But in my motor i don't see how i can implement it. Is there another way to avoid this problem? what is the regen shunt that you mentioned above?
