Our friend the post person has been again with a weighty box of joy!
These stepper motors are type SY42STH47-1684A so there’s plenty of power to spare.
They also come with a flat part on the drive shaft and a REALLY long cable. There are plenty of cheaper motors that have a round shaft and / or short cables.
Time to bolt these on to the frame and double its weight.
Note: No, you don’t need 10 motors. We’re actually building 2 MendelMax machines 😉
