Hi Zach, would there be any possibility of being able to speak with you directly? It's about your SushEngine project. Regards!

You have it in the Robot Arm assembly, it's from shaft 1 ", outside diameter 1- 9/16". The reference is 5909K36 of McMaster Carr, you can look on their website for more information. In Europe I have not found those dimensions exactly, the most similar is the AXK2542, which has a larger external diameter.

@Chris Annin Wow, the people who use gecko drivers speak very well of them, but they are very expensive. Can the optocoupler solution be good or not fast enough for the PWM outputs? The drv8825 for the larger motor would fall short, you could use a tmc2260. These drivers are used in 3d printers and work quite well.

I think I read that you made the printed version in ABS. I'm thinking of doing it in PETG or in POM, which according to the POM is more resistant than ABS and suffers less wear. Perhaps with this material you can reach a payload somewhat lower than with aluminum, but more than 700gr. what do you think about that?
