Hi selexin, have you finished assembling the robotic arm? I’m having some mechanical problems with the two motors of articulation 2 (the ones that have helical gears and make contact with the indentations). Let me know if you had any problems with it or which other issues you might be having. My email is carlosnj95@gmail.com and my discord username is Sukistrukis#7685 or sukistrukis.
