Any suggestions for a better function?

btw haha very funny https://gyazo.com/2a1e89aa719d909984b4c78533518531

Iā€™m not rebelling against anything. Iā€™m refusing to help you because you have a shitty attitude and are unwilling to listen because im not providing the answer you want. I already told you to have a look at the repetier firmware. All you are doing is antagonizing now so im muting the thread. Good luck with your project.

OP, if youā€™re here to get assistance, I suggest you leave your smarty pants at the door and act like someone whoā€™s adequately professional.

Man this forum is wack. I already figured it out. 1v1 me.

Everyones braincells here are too busy being triggered af. Take that somewhere else.

Past rudeness aside, what youā€™re looking for is PID, or PIDf if you feel like getting fancy.

Hereā€™s a good writeup on PID control, and how it works for actuators: http://blog.opticontrols.com/archives/344

Now, all of this assumes your arm has a decently noise-free sensing setup. Is this arm youā€™ve made controlled by any encoders, potentiometers, or other sensors? Or are you working blind off the stepper? Blind control can also be done, but youā€™ll end up doing some motion profiling, which is an entirely different discussion.

If that first link isnā€™t enough detail to get you where you need to be, hereā€™s a much longer (and steeper) explanation of the control theory youā€™ll be needing: https://www.cds.caltech.edu/~murray/courses/cds101/fa02/caltech/astrom-ch6.pdf

No itā€™s only motion profiling Iā€™m talking about. Hence a speed curve. I donā€™t want to implement PID yet.

Therefore only a function is needed. Idk why everyone here over complicates itā€¦

Iā€™ll bite: Why skip PID, and go straight for motion profiling?

Because I have no feedback loop yet.

Also miss me with that gay shit because Iā€™d still need a motion profile if I were to have it PID controlled.

OPā€™s behaviour just went down hill, so into the (freight) container this goes.
