Patrick, I'm glad you liked the video! I will definitely try to remember to post a link to my thesis once it is 100% done. I just got the linear moves to work along with circular moves with an adjustable parameter for (moves/cm). Those are the only two types of moves I will be doing since it is the...

Is your thesis done yet Soronemus? Would love to read more about it. It is not completely done yet, but I have made a ton of progress. I have the wiring done, the motors attached, and the controls are done. The motion is very smooth. I am in the process of testing the resolution/repeatability of th...

Thanks for the advice Bob. Here is a video I made of the current method of control I am using if you are interested. https://www.youtube.com/watch?v=ukVbKR77Fvo It works great for 'joint' moves, but for linear moves where I have to do lots of small joint moves continuously flowing into each other it...

Are you saying that each stepper motor needs to execute something more complex than the usual trapezoidal velocity profile or is that sufficient? If it is, then any off-the-shelf microstepping controller board, eg Phidgets 1067, would suffice. Bob, part of my thesis is making the stepper motors fol...

Hello! I am a mechanical engineering graduate student, my masters' thesis is the design, construction, and control of a linear delta robot. My question to you guys is whether a phidget is capable of switching digital outputs on/off at a frequency high enough to drive a stepper motor at high speeds w...
