Very cool Richard. Looks like you are having some design and print success.
Wow, it looks great. What motors do they use? And what torque do they have to move their legs? I have been designing mine for 4 months and hopefully soon move them. regards
Got it to work with Nema 17 Stepper Motor 59Ncm(84oz.in) 2A 17HS19-2004S, also using from Sparkyman1 a Planetary Gear Box which give me about 50:1 reduction.
