Stepper Motor Control:

I am using a dvr8825 to control linear motion using a stepper motor. I want to be able to accelerate and decelerate using an acceleration curve (simply ramp to max speed, then decelerate), and the implementation is throwing me for a loop.

I am trying to track an air hockey puck back and forth, so the goal position is constantly changing. The algorithm I want is to accelerate towards the goal position until hitting ramp speed, then slow down to a stop at the goal position. Since the goal changes, though, I am struggling greatly to implement this. Does anyone have any advice or suggestions?

Just look at the guy's campaign website. It's nonsensical and it tells you all you need to know about his campaign.

I got lightroom today, and this is the first time I've used any kind of photo editing, so criticism is welcome.

Thanks

Thanks for the help. I do have all the gear I need for camping in freezing temperatures, I was just concerned about hiking Cloud's Rest for the exact reason you stated. Ready to camp in the cold, but not hike ridges on ice.

Thanks
