Hello Dima! Thanks for replying - I really admire your work with mrcal, and have used it for a while in my work. And lensboy is heavily inspired by mrcal. > Is your splined representation compatible with the mrcal splined stereographic m

Hello! I'm the creator of SlamDunk, and I use it daily in my day-to-day work for 3D visualizations. I really like it, so I thought I'd share it.

Did you try using the previous configuration as an initial guess to the numerical optimizer? If the next position is close to the previous one, the solver should be very quick. Also, you can probably get much faster results if you obtain th

Thanks! Exactly - I feel much more comfortable talking about the hardware at work now after having made this and feel more confident about making something more advanced. This is my first printer so I don't have anything to compare it

Right? I'm thoroughly enjoying that rush :D

Really cool 4dof robot - thanks for the reccomendation

Thank you, great to hear!

That's true - using numerical optimization was just the simplest/fastest way to get it working :P

Nice - did you just chuck it into wolfram alpha or sympy? How'd you get it?

Thank you! I made it like that purely for fun, this project was not intended to be useful, or have the best mechanical design :P Using Gcode is a good idea, though it does seem a bit overkill for this simple application

Oh wow that is refined indeed - I'll check it out, thanks!

That's very inspiring for me to hear, thank you! Glad it's useful.

"Mastered" is a strong word, but thanks!

Hahaha wow that is scrappy as hell - it does look difficult to get right :P

Well in what context does it matter? If it's useful for you to learn, then it matters, right? There are also endless applications for hardware, but I guess to make a viable product you probably need a sizeable team of people.

Yeah - I'm using mediapipe for hand tracking, which is straight out of the box. Then I can just make the robot draw the exact sequence of dots my index finger drew :)
