Arduino programming + motor control (Stepper robots, for robotics - toy, not industrial) cobbled with 3D printing. I've always been fascinated with robotics, and the barrier to entry is getting lower by the second. But I want to know all the details, so I'm going slow and steady at it (Like, instead of using libraries - at least when learning - I'm coding 100% of the stepper motor control routines). I plan on making…
Make sure you have proper ventilation and air filtering for that 3d printer. https://3dinsider.com/3d-printer-fumes/
Luckily I'm using PLA for printing, but I do plan to take the printer out to the balcony once I start printing "big" pieces.
