Forearm added. Wow had a huge heart attack thinking i messed the whole design up and wasted an hour on a nonexistent problem, because of a mistake in initial dimensioning that would have ended up with the upper arm being completely straight up and down! Well first time making a robot arm so learning experience ig. other than cad i also tuned vref on all DRV88 stepper motor drivers with a demo link here https://www.youtube.com/shorts/iS-jFYrCbGg.
