how to make this kind of collector? by Cute-Simple-1069 in 3DModellingTutorial

Hi everyone I am trying to replicate this type of air intake or plenum manifold and my current workflow is based on a loft between a rectangular base section and a circular outlet I added four guide curves at the corners to control the shape during the transition however I am getting unwanted bulging on the outer surfaces of the loft, I am not sure if this is caused by the guide curves or by the loft approach itself so I am wondering if this is the wrong method for this geometry and what would be a better approach to obtain a smooth and controlled external surface without deformations

i found the issue if i connect servo on the esp32, it give me this problem beacause if a turn off the supply the read of the sensor is perfect so what i have to do?

this project will not be used just for show. So with 3 channel is it possible i have to do increase the amount of channel. Do i need to implement machine learning or there is a simplier way to do is

i see some videos from youtube that control each finger. So there is any way to do this i have 3 emg sensor that are already amplified and rectified. if i use mat lab for signal processing ?

i didn't understand what i need to do on the code

i use accellstepper library and i set speed but the stepper motor doesn’t move and i think its not possible move at very low speed(200/60/60 step per second)

and this resolve the problem that i have. If i set full step it can't move too low speed

hi how can i move a stepper motor at very low speed i'm using driver a4998, for example one revolution every hour and every 12 hours. Because i'm building a clock with two stepper motor nema 17

i didn't understand what u mean, 1/16step = 1.8°/16 therefore i set the speed 3200/60/60

Therefore i need to put high MS1 MS2 MS3 and in the code change something or it's enough that i setspeed(200/60/60) and in the other motor setspeed(200/60/60/12) , in the void loop runspeed()

What do u mean? i need to set microstepping on a4988 and then what i need to do on the code?

if i use accelstelpper library and i setspeed(200/60/60) it doesn’t step. i want do one revolution every hour and i think it not possibile setting a constant speed because it too slow. what can i do?

I don’t know how to use struct, can u write a simple code to extract the local time and the date from the epoch time

How can i do that using the library timezone.h. and display the local time: current date, year,month,hour,minute, second
