Шось позаписую. Зібрано прототип на базі
Шо я бачу. Шо 1:23 явно для 3Д друку - це перебір. Зміщення +-1.0 замало, бажано раза в півтора підняти.
- зовнішнього підшипника 52х40х7
- внутрішнього підшипника спочатку на 8х22х7, потім замінено на 10х19х5
Шо я бачу. Внутрішній треба спробувати всунути 15х24х5, для зміцнення валу
База
Базу пропоную проєктувати на базі автомобільної ступіци. Мені здається шо це може бути найпростіший, та мабуть найдешевний варіант. Треба шоб конструкція витримувала навантаження на ізлом, мала б надійне кріплення до кузова.

Questions
How big is the Dcesc ga25 PCB?
It measures 100 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Dcesc ga25 use?
219 parts, built around the ATA6561-GAQW-N, EG3112, ST1S14PHR and DRV8870DDA. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Dcesc ga25 KiCad files?
From the baden/roboarm repository on GitHub, at the commit this page was made from: the board is controllers/dcesc-controllers-copy/dcesc-ga25-copy.15.43/dcesc-ga25.kicad_pcb and its schematic controllers/dcesc-controllers-copy/dcesc-ga25-copy.15.43/dcesc-ga25.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dcesc ga25 design in my own project?
Its repository states no licence, so its author keeps all rights: ask baden before reusing the design.
