Marco, I find it bizarre that pretty much every one of your topics is something that I am also following...Great stuff and the humour is better than anything on TV 👍😂
I solve for movement speed, rather than position. If I want to move to a specific position, then I change the move speed based on the error and I can smooth the approach however I want. This is really nice for an application like this.
Actually the PID for speed control would have worked wonders with that enconder, only if you took the time to make proper controller calculations, instead of a mediocre sintonization without any mathematical model.
Never seen or heard the word 'sintonization' before and had to look it up. Agreed on the PID loop, it should work fine especially with the encoder resolution and rigidness of that system.
Actually, screw the math model, they are never close. BUT....I would have gotten rid of the integral altogether until steady state....and only then for critical position tolerance. The D term IS ABSOLUTELY USED in the real world if you want to control both position and velocity. I would've had that loop balanced in a heartbeat 😎

Such ancient days. The Testing Towers are so small and devoid of Keithly Klassik Brown.

Thanks for sharing! I've been wanting to try this approach, now I know it can work 🙂
You need a bit more coffee next episode.. oh wait, this was 4 years ago.. nevermind :)

Great video Marco as usual :)
This? Pure cringe material! I had hoped, nobody would ever find this again :)
0:35 Was used in very old 5.25 types floppy drives, no backlash what so ever.
You can use higher PWM frequency for reduce noise sound
+omsonic Sodium persulfate! It's almost the same
Marco Reps the only thing cringe about these old videos is this method of replying to someone
Not sure if I'll get an answer, but whats the RPM of the motor? at 4000ppr can the arduino still read the pulses reliably?
nice etch tank ! ammonium persulfate ?
👍👍
whats that on the piece of glass in front of you at 5:17?
cant you sust sync the stopping of the slider with the trigger of the camera
Woow after watching your recent videos, you sound so weird here 😆
Why not share the code on Github or elsewhere?
