I've been investigating (slowly, with a lot of help from nprofile1qy2hwumn8ghj7un9d3shjtnddaehgu3wwp6kyqpqvtdedddfh69kqpu5rskguwtdx5np364kh72hrdlxf9ptkx9sfkuqhlg2mf (nprofile…g2mf) and nprofile1qy2hwumn8ghj7un9d3shjtnddaehgu3wwp6kyqpqgxjct94ayjwhj03eukvxkpfz5vlvs9vmpfy2y5avg48sw237kscs2sx2x0 (nprofile…x2x0) ) a #DIY #CNC build. In the process, I have learned a lot of things, and felt like sharing some of what I've learned.
One example is from this video: https://www.youtube.com/watch?v=clgpZJFoqIQ
The tl;dws are:
1. Stepper motors (closed or open loop) never hit their holding torque at _any_ rotation.
2. Servos have less peak torque, but hold it at _any_ rotation speed they're rated for.
Conclusion for me: servos and gearing are best here.
