Why are you defending him?I am holding up a mirror. I am disappointed you fail to understand that.
Is that the environment you want here?"Rude" is a significant improvement over "personal attack".
Hello,Your pictures, video didn't attach. You should at least provide links, because not many outside London know what a bus blind is.
I am doing a project where I am trying to make a functioning bus blind, the ones you see on the front of TFL buses.
This has two shafts which spin connected with pulleys to a motor which has 17metre length of material which is to be transferred back and forth (kind of like a cassette tape). Originally they all ran on one belt, but because of the diameter of one shaft having an extra 5cm radius of material, it didn't keep tension due to it having different rotation speeds. I, therefore, hooked up separate 12volt stepper motors with individual belts to each shaft with one running at a time. This allows the off motor to keep a bit of tension on the material but not completely. I am also having problems where the motor is struggling to pull the weight.
Does anyone know how to troubleshoot this, we have considered a tension bar but it won't fit in the box so it seems like it should be done through the code. The code in my mind should be written as an exponential wave over time and speed with both the motors.
I've attached images / video of it.
Any help or suggestions would be amazing!
